North Dakota Crude Oil Production Continues to Rise

North Dakota's oil production averaged 660 thousand barrels per day (bbl/d) in June 2012, up 3% from the previous month and 71% over June 2011 volumes. Driving production gains is output from the Bakken formation in the Williston Basin, which averaged 594 thousand bbl/d in June 2012, an increase of 85% over the June 2011 average. The Bakken now accounts for 90% of North Dakota's total oil production.

Production gains in the Bakken formation are the result of accelerated development activity, primarily horizontal drilling combined with hydraulic fracturing. According to the North Dakota Department of Mineral Resources, there were a total of 4,141 producing wells in the North Dakota Bakken in June 2012, up 4% from May 2012 and up 68% from the number of producing wells in June 2011.

Increasing oil rig counts underscore the quickening pace of drilling in the region. Data from Baker Hughes show that in the Williston Basin, the average weekly count of actively drilling horizontal rigs totaled 209 in June 2012, essentially unchanged from the May 2012 average but 26% above the June 2011 average (see below). Most of these rigs are positioned in the Bakken.

graph of Monthly rig count: Williston Basin, as described in the article text

The transportation system oil pipelines, truck deliveries, and rail to move crude oil out of the area is being affected by constraints due to growth in crude oil production from the Bakken formation. As a result of these bottlenecks, the difference between spot prices for Bakken crude oil and West Texas Intermediate (WTI) crude oil expanded through much of the first quarter of 2012. The spread has generally narrowed in recent weeks, however, reflecting the addition of rail transport facilities and increased refinery capacity in the Bakken area.

U.S. Proved Reserves Increased Sharply in 2010

Test drive our video analysis and trade idea service for only $1.00

On August 1, the U.S. Energy Information Administration (EIA) released its summary of the nation's proved reserves of oil and natural gas for 2010. Proved reserves of both oil and natural gas in 2010 rose by the highest amounts ever recorded in the 35 years EIA has been publishing proved reserves estimates.

Technological advances in drilling and higher prices contributed to gains in reserves. The expanding application of horizontal drilling and hydraulic fracturing in shale and other "tight" (very low permeability) formations, the same technologies that spurred substantial gains in natural gas proved reserves in recent years, played a key role. Further, rising oil and natural gas prices between 2009 and 2010 likely provided incentives to explore and develop more resources.

graphs of proved reserves and changes in proved reserves for oil and natural gas, as described in the article text

Oil proved reserves (which include crude oil and lease condensate) rose 12.8% to 25.2 billion barrels in 2010, marking the second consecutive annual increase and the highest volume since 1991. Natural gas proved reserves (estimated as "wet" natural gas, including natural gas plant liquids) increased by 11.9% in 2010 to 317.6 trillion cubic feet (Tcf), the twelfth consecutive annual increase, and the first year U.S. proved reserves for natural gas surpassed 300 Tcf.

Proved reserves reflect volumes of oil and natural gas that geologic and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. It should be noted that the 2010 summary was delayed due to budgetary restrictions that limited EIA's survey data collection efforts.

EIA: Rail Deliveries of Crude Oil and Petroleum Products up 38% in First Half of 2012

How To Position Yourself for a 10 Year Pattern Breakout

Railroads are playing a more important role in transporting U.S. crude oil to refineries, especially oil production from North Dakota's Bakken formation where there is limited pipeline infrastructure to move supplies. The amount of crude oil and petroleum products transported by U.S. railways during the first half of 2012 increased 38% from the same period in 2011, according to industry data.

The number of rail tanker cars hauling crude oil and petroleum products totaled close to 241,000 during January-June 2012 compared to 174,000 over the same period in 2011, according to the Association of American Railroads (AAR). Rail deliveries of crude oil and petroleum products in June alone jumped 51% to 42,000 tanker cars from a year earlier to an average weekly record high of 10,500 tanker cars for the month.

One rail tanker car holds about 700 barrels. This would be equivalent to about 927,000 barrels per day (bbl/d) of oil and petroleum products shipped, on average, during the first half of 2012 versus 673,000 bbl/d in the same period in 2011, and June 2012 shipments were almost 980,000 bbl/d.

graph of Average weekly U.S. rail carloads of crude oil and petroleum products, as described in the article text
Source: U.S. Energy Information Administration, based on Association of American Railroads.
Note: Crude oil and petroleum products rail shipments do not include ethanol. 



In 2009, crude oil accounted for 3% of the combined deliveries in the oil and petroleum products category tracked by AAR. The trade group estimates crude oil now accounts for almost 30% of the rail deliveries in this category, and says that crude oil is responsible for nearly all of the recent growth.

Much of the growth in shipping oil by rail is due to the rise in North Dakota's oil production, which has more than tripled in the last three years. North Dakota surpassed California in December 2011 to become the third biggest oil producing state and took over the number two spot from Alaska in March 2012.

Most crude oil is moved in the United States by pipeline. However, because of limited pipeline infrastructure in North Dakota's Bakken region, oil producing companies there rely on rail to move their barrels. Shipping oil by rail costs an average $10 per barrel to $15 per barrel nationwide, up to three times more expensive than the $5 per barrel it costs to move oil by pipeline, according to estimates from Wolfe Trahan, a New York City based research firm that focuses on freight transportation costs. Wolfe Trahan also notes that using rail tank cars allows oil producers to separate grades of crude more easily and ensure their purity than when different oils are mixed in a pipeline.

Argus Media reports that rail rates for unit trains moving Bakken oil to major refining centers on the Gulf Coast are about $12.75 per barrel to St. James, Louisiana and $12.25 per barrel to Port Arthur, Texas. The unit train delivery rate to New York Harbor is around $15 per barrel.
BNSF is the biggest railway mover of U.S. crude, transporting one-third of Bakken oil production alone with unit trains carrying up to 85,000 barrels of oil. The company's carloadings of crude oil and petroleum products increased 60% during the first six months of 2012.

Crude Oils Have Different Quality Characteristics

Many types of crude oil are produced around the world. The market value of an individual crude stream reflects its quality characteristics. Two of the most important quality characteristics are density and sulfur content. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. The crude oils represented in the chart are a selection of some of the crude oils marketed in various parts of the world. There are some crude oils both below and above the API gravity range shown in the chart.

graph of Density and sulfur content of selected crude oils, as described in the article text
Source: U.S. Energy Information Administration, based on Energy Intelligence Group—International Crude Oil Market Han

Crude oils that are light (higher degrees of API gravity, or lower density) and sweet (low sulfur content) are usually priced higher than heavy, sour crude oils. This is partly because gasoline and diesel fuel, which typically sell at a significant premium to residual fuel oil and other "bottom of the barrel" products, can usually be more easily and cheaply produced using light, sweet crude oil.

The light sweet grades are desirable because they can be processed with far less sophisticated and energy intensive processes/refineries. The figure shows select crude types from around the world with their corresponding sulfur content and density characteristics.

The selected crude oils in the figure are not intended to be comprehensive of global crude production. Rather, they were grades selected for the recurrent and recently updated EIA report, "The Availability and Price of Petroleum and Petroleum Products Produced in Countries Other Than Iran."

Rising Production in the Permian Basin

Get our Free Trading Videos, Lessons and eBook today!

The Permian Basin, a long time oil and natural gas producing region in west Texas and eastern New Mexico, is showing signs of new life. The active rig count has grown from 100 rigs in mid 2009 to over 500 rigs in May 2012. According to data from the Texas Railroad Commission and the New Mexico Energy, Minerals and Natural Resources Department, oil production from the Permian has increased fairly steadily over the past few years, reaching the 1 million barrels per day (bbl/d) threshold in late 2011, the first time since 1998.

Sources: U.S Energy Information Administration, based on Baker Hughes, Railroad Commission of Texas, and New Mexic

Growing oil production in the Permian Basin and other Texas plays, most notably the Eagle Ford shale, may be starting to strain existing takeaway capacity and is creating a need for Texas oil to serve more distant refineries. While new pipeline projects are scheduled to come online, current transportation constraints have caused Permian crude oil, which is priced in Midland, Texas, to sell at a significant discount to WTI beginning in January 2012.

Crude Oil Distillation and the Definition of Refinery Capacity

A crude oil refinery is a group of industrial facilities that turns crude oil and other inputs into finished petroleum products. A refinery's capacity refers to the maximum amount of crude oil designed to flow into the distillation unit of a refinery, also known as the crude unit.

The diagram below presents a stylized version of the distillation process. Crude oil is made up of a mixture of hydrocarbons, and the distillation process aims to separate this crude oil into broad categories of its component hydrocarbons, or "fractions." Crude oil is first heated and then put into a distillation column, also known as a still, where different products boil off and are recovered at different temperatures.

diagram of Crude oil distillation unit and products, as described in the article text
Source: U.S. Energy Information Administration.  

Lighter products, such as butane and other liquid petroleum gases (LPG), gasoline blending components, and naphtha, are recovered at the lowest temperatures. Mid-range products include jet fuel, kerosene, and distillates (such as home heating oil and diesel fuel). The heaviest products such as residual fuel oil are recovered at temperatures sometimes over 1,000 degrees Fahrenheit.

The simplest refineries stop at this point. Although not shown in the simplified diagram above, most refineries in the United States reprocess the heavier fractions into lighter products to maximize the output of the most desirable products using more sophisticated refining equipment such as catalytic crackers, reformers, and cokers.

Annual Energy Outlook 2012.....Three Cases for the Future of World Oil Prices

The Annual Energy Outlook 2012 (AEO2012) presents three alternative paths for world oil prices based on different production and economic assumptions. Among these cases, the real (constant 2010 dollars) oil price in 2035 ranges from $62 per barrel in the Low Oil Price case to $200 per barrel in the High Oil Price case, with the Reference case at $145 per barrel.

The oil price in AEO2012 is defined as the average price of light, low-sulfur crude oil delivered to Cushing, Oklahoma, which is similar to the price for light, sweet crude oil traded on the New York Mercantile Exchange (West Texas Intermediate, or WTI).

graph of Average annual world oil prices in three cases, as described in the article text

Factors considered in AEO2012 that affect supply, demand, and prices for petroleum in the long term are:

* World demand for petroleum and other liquids

* Organization of the Petroleum Exporting Countries (OPEC) investment and production decisions

* The economics of non OPEC petroleum supply

* The economics of other liquids supply

The Reference case of AEO2012 indicates a short term increase in oil price, returning to price parity with the Brent oil price by 2016, as current constraints on pipeline capacity between Cushing and the Gulf of Mexico are moderated.

The Low Oil Price case results in a projected oil price of $62 per barrel in 2035. The Low Oil Price case assumes that economic growth and demand for petroleum and other liquids in developing economies (which account for nearly all of the projected growth in world oil consumption in the Reference case) is reduced.

Specifically, the annual gross domestic product (GDP) growth for the world, excluding the mature market economies that are members of the Organization for Economic Cooperation and Development (OECD), is assumed to be 1.5 percentage points lower than that of the Reference case in 2035 (only a 3.5% annual increase from 2010 to 2035), which reduces their projected oil consumption in 2035 by 8 million barrels from the Reference case projection.

While non OECD oil consumption is more responsive to lower economic growth than to prices, oil use in the OECD region increases modestly in the Low Oil Price case. In this lower price case, the market power of OPEC producers is weakened, and they lose the ability to control prices and to limit production.

In contrast, the High Oil Price case assumes prices rise to $186 per barrel by 2017 (in 2010 dollars) and then increase to $200 per barrel by 2035. These higher prices result from higher demand for petroleum and other liquid fuels in non OECD regions than projected for the Reference case. In particular, the projected GDP growth rates for China and India are 1.0 percentage point higher in 2012 and 0.3 points higher in 2035 than the rates in the Reference Case.

Overall, in 2035 it is projected that 4 million barrels per day will be produced above the Reference Case level, even though projected oil consumption in the mature, industrialized economies is reduced.

Drop in U.S. Gasoline Prices Reflects Decline in Crude Oil Costs

Today’s Stock Market Club Trading Triangles

Since reaching a recent peak of $3.94 per gallon on April 2, the average retail price U.S. drivers paid for gasoline has fallen for 12 weeks in a row to $3.44 per gallon, according to EIA's weekly motor fuel survey. The drop in gasoline prices largely reflects the decline in crude oil prices (see chart below), which have historically comprised the biggest part of the pump price.

The national average price for regular unleaded gasoline fell 50 cents per gallon over the 12-week period, while the spot prices for West Texas Intermediate (WTI) crude oil declined the equivalent of 63 cents per gallon and Brent crude oil fell the equivalent of 81 cents per gallon. WTI and Brent are among the world's leading oil pricing benchmarks.

graph of Weekly retail gasoline and spot crude oil prices, March 2012 - June 2012, as described in the article text

If crude oil price changes are fully passed through to consumers, for every $1 per barrel change in crude oil prices, consumers could expect to see a 2.4-cent-per-gallon change in retail gasoline prices. However, EIA analysis indicates that generally about 50% of the crude oil price change is usually passed on to consumers at the pump within two weeks, and 80% is generally passed on within four weeks. Gasoline prices are also sensitive to conditions affecting particular regional markets, such as significant refinery outages on the West Coast this spring that led to higher prices in that area.

The price of crude oil accounts for about two thirds of the retail price of gasoline. Refining costs, distribution and marketing costs, and state and federal taxes make up the rest of the retail gasoline price. Pump prices vary by region, with some drivers paying more or less for gasoline than the national average depending on where they live (see chart below).

graph of U.S. regional average gasoline prices, 2012 peack price and most recent weekly price, as described in the article text

Concerns that a weak global economy will lead to reduced petroleum demand has contributed to lower crude oil prices. However, part of the reason retail gasoline prices have not dropped as much as crude oil prices is that U.S. gasoline demand has started to show some growth in recent months. During the first quarter of 2012, monthly EIA data shows U.S. gasoline demand was down about 1.4% from the first quarter of last year. However, since the gasoline price peak, weekly EIA data indicate that gasoline demand has started to strengthen, with demand down only 0.9% in April compared to a year earlier and up by 0.2% in May.

The current 12 week drop in gasoline costs is the second longest period of declining pump prices recorded by EIA's weekly fuel price survey since the drop at the end of 2008, when pump prices fell for 15 straight weeks.

North American Spot Crude Oil Benchmarks Likely Diverging Due to Bottlenecks

Gold and Silver on the Verge of Something Spectacular

West Texas Intermediate at Cushing, Oklahoma (WTI Cushing), a light, sweet crude grade, is North America's most closely observed crude oil price benchmark and the underlying commodity of the NYMEX crude futures contract. Until 2008, all North American crude grades broadly tracked fluctuations in WTI Cushing prices and were clustered within about $8 per barrel of the WTI Cushing price. Pricing differences between crude grades were largely explained by the different quality characteristics of the crude oil in each location and transportation costs to Cushing, the delivery point of the NYMEX contract.

Since 2008, however, the price differences between WTI Cushing and other North American crude oil benchmarks have increased sharply (see chart below). In addition to WTI, other crude grades have emerged as alternative benchmarks. In particular, the Argus Sour Crude Price Index (ASCI), a weighted average of prices for several offshore Gulf of Mexico sour crude grades, has become the benchmark or reference used for assessing the price of several imported grades sold on a long-term contract basis, including Saudi Arabian and Kuwaiti crude grades.

graph of spot crude price minus spot WTI (Cushing, OK) crude oil prices, January 1, 2005 - June 19, 2012, as described in the article text

Transportation constraints in the wake of rising production from inland fields in Canada, North Dakota, and Texas are one of the main drivers of the growing price discrepancy between crude grades since 2008. Limited pipeline capacity has made it difficult to bring crude oil out of the center of the continent, lowering all the affected benchmarks compared to prices outside the area. But within the constrained area, prices have also diverged from each other, reflecting local transmission bottlenecks within the larger constrained area. For example, crude oil benchmarks for the Bakken, Western Canada, and West Texas Sour (Midland, Texas) have traded at a discount to WTI Cushing. Rising production in the Bakken and West Texas have exacerbated these price differences. Outside the constrained areas, benchmarks like Louisiana Light Sweet, Alaska North Slope, and Mars Blend in the Gulf of Mexico reflect premiums to WTI Cushing, sometimes significant.

The phrase "transportation constraints" refers to a broad range of logistic issues, with inadequate pipeline capacity being the most common issue. However, EIA is not aware of any crude oil production capacity being shut in because of a lack of capacity to move the oil. In the short term, production surges and/or pipeline shutdowns force oil producers to compete with each other for more expensive transport options: rail and then truck. In the longer term, additional transportation capacity (rail and pipeline) is likely to be built, which should lower the cost of transporting the oil to markets.

Some North American crude oil benchmark locations are identified in the map below.

Working Crude Oil Storage Capacity at Cushing, Oklahoma Rises

As of March 31, 2012 working crude oil storage capacity at the Cushing, Oklahoma storage and trading hub was 61.9 million barrels, an increase of 6.9 million barrels (13%) from September 30, 2011 and 13.9 million barrels (29%) from a year earlier, as reported in EIA's recently released report on Working and Net Available Shell Storage Capacity.

Utilization of working storage capacity on March 31, 2012 was 64%, an increase from the 53% observed in September 2011, but lower than the 86% observed on March 31, 2011. The report also noted that operating shell storage capacity increased 8.1 million barrels (12%) from September 30, 2011 to reach 74.6 million barrels.

Both storage capacity and the level of inventories held at Cushing are closely watched market indicators, as Cushing is the market hub for West Texas Intermediate (WTI) crude oil that is the basis for crude oil futures contracts traded on the New York Mercantile Exchange. High inventory levels at Cushing have been a symptom of transportation constraints that have resulted in WTI trading at a discount relative to comparable grades of crude oil since early 2011.

graph of Crude oil storage capacity and inventories at Cushing, Oklahoma




Growing volumes of U.S. crude oil production, along with a higher level of imports from Canada, have helped contributed to the record levels of inventories at Cushing. Increased flows of crude oil from these two sources, along with expectations for future increases, have consequently created the need for additional storage at the hub.

Weekly data show that as of June 1, 2012, crude oil inventories held at Cushing were 47.8 million barrels, the highest level on record and very close to total working storage capacity as of March 2011. However, due to the growth in storage capacity between March 2011 and March 2012, the utilization rate for working storage capacity at Cushing has actually declined over the past 14 months.

U.S. Crude Oil Production in First Quarter of 2012, Highest in 14 years

Strong growth in U.S. crude oil production since the fourth quarter of 2011 is due mainly to higher output from North Dakota, Texas,and federal leases in the Gulf of Mexico, with total U.S. production during the first quarter of 2012 topping 6 million barrels per day (bbl/d) for the first time in 14 years.

graph of United States crude oil Production, 1998-2012, as described in the article text

After remaining steady between 5.5 million and 5.6 million bbl/d during each of the first three quarters of 2011, EIA estimates that U.S. average quarterly oil production grew to over 5.9 million bbl/d during the fourth quarter and then surpassed 6 million bbl/d during the first quarter of 2012, according to the latest output estimates from EIA's May Petroleum Supply Monthly report (see chart below). The last time U.S. quarterly oil production was above 6 million bbl/d was during October-December 1998.

graph of United States quarterly crude oil Production, 2011-2012, as described in the article text

The roughly 6% growth in U.S. oil production from October 2011 through March 2012 is largely the result of increases in oil output in North Dakota, Texas, and the Gulf of Mexico. After passing California in December 2011 to become the third largest oil producing state, North Dakota then jumped ahead of Alaska in March 2012 as the state with the second largest oil output. Texas remains far ahead in the number one production spot.

OPEC Spare Capacity in the First Quarter of 2012 at Lowest Level Since 2008

Get our Free Trading Videos, Lessons and eBook today!

The U.S. Energy Information Administration (EIA) estimates that global spare crude oil production capacity averaged about 2.4 million barrels per day (bbl/d) during the first quarter of 2012, down about 1.3 million bbl/d from the same period in 2011 (see chart below). The world's spare crude oil production capacity is held by member countries of the Organization of the Petroleum Exporting Countries (OPEC). Spare capacity can serve as a buffer against oil market disruptions, and it gives OPEC additional political and economic influence in world markets. There is little or no spare capacity outside of the OPEC member countries.

graph of Quarterly OPEC spare crude oil capacity and WTI spot prices, as described in the article text

Spare crude oil production capacity is now less than 3% of total world crude oil consumption—the lowest proportion since the fourth quarter of 2008—based on EIA estimates.

Spare crude oil production capacity is an important indicator of producers' ability to respond to potential disruptions; consequently, low spare oil production capacity tends to be associated with high oil prices and high oil price volatility. Similarly, rising spare capacity tends to be associated with falling oil prices and reduced volatility. However, spare capacity must also be considered in the context of a number of other market factors that can drive crude oil prices, such as global supply, demand, and inventory levels.

EIA defines spare crude oil production capacity as potential oil production that could be brought online within 30 days and sustained for at least 90 days, consistent with sound business practices. This does not include oil production increases that could not be sustained without degrading the future production capacity of a field.

Williston Basin Crude Oil Production and Takeaway Capacity are Increasing

Crude oil production from the Williston Basin (primarily the Bakken formation) recently increased to more than 600 thousand barrels per day (bbl/d), according to Bentek Energy, LLC (Bentek), testing the ability of the transportation system, oil pipelines, truck deliveries, and rail to move crude oil out of the area (see chart below). The current price gap between Bakken crude oil and West Texas Intermediate (WTI) shows the effects of this constraint. Bentek projects more transportation capacity coming online in 2012, potentially alleviating this constraint.

graph of Williston Basin crude oil production and takeaway capacity, as described in the article text


 Due to pipeline capacity constraints, Williston Basin producers rely on rail and trucks to move additional crude oil out of the region. Because of these transportation constraints, Bakken crude oil currently sells at a discount of $7.50 per barrel to WTI. This discount was as much as $28 per barrel in February 2012 and is expected to continue as long as transportation constraints persist.

Currently, North Dakota has only one refinery, which processes about 58 thousand bbl/d of crude oil. Crude oil is delivered to other markets using a combination of pipeline, rail, and truck. Delivery capability as of April 2012 was: 450 thousand bbl/d by oil pipeline; 150 thousand bbl/d by rail; and small volumes by truck. However, in 2012, incremental additions to rail and oil pipeline capacity for the Williston Basin could total 350 thousand bbl/d.

EIA: U.S. Imports of Nigerian Crude Oil Have Continued to Decline in 2012

The trend of declining crude oil imports into the United States continued in the first month of 2012. There has been a particularly sharp decline in imports from Nigeria due to the idling in late 2011 of two refineries on the East Coast, which were significant buyers of Nigerian crude, and reduced imports by refiners on the Gulf Coast. Prior to the idling of the refineries, Nigeria typically accounted for about 10% of the crude oil imported into the United States; in January, that share dropped to about 5%.

graph of Monthly regional U.S. crude oil imports from Nigeria, January 2005 - January 2012, as described in the article text

 In January 2012, imports from Nigeria totaled just 449 thousand barrels per day (bbl/d), a 54% (519 thousand bbl/d) decrease from January 2011, marking the lowest monthly import total from the country since 2002. One third of this decline was the result of two idled Philadelphia area refineries. ConocoPhillips' Trainer refinery (idled in September 2011) and Sunoco's Marcus Hook refinery (idled in December 2011) imported a combined 173 thousand bbl/d of Nigerian crude in January 2011. Most of the remaining decrease in Nigerian imports was the result of several Gulf Coast refiners reducing Nigerian imports in favor of domestically produced crude.

The idled refineries were suited to run light-sweet crude oils, and Nigerian crude oils tended to match well with that requirement. However, because of their quality, Nigerian crude oils are often expensive compared to heavier or more sour crude oils used by many of the Gulf Coast refineries.

 Additionally, Nigerian crudes are currently expensive compared to some of the inland domestic light sweet crudes of similar quality such as West Texas Intermediate (WTI), Bakken, and Eagle Ford. Given the growing production from the Bakken and Eagle Ford formations and associated transportation constraints, these inland crudes have been selling at a discount to waterborne crudes on the Gulf Coast, providing refiners in that area further incentive to switch from imported crude to inland, domestically produced crude when available.

Preliminary weekly data indicate the trend of decreasing Nigerian imports continued in February and March with March imports averaging just 301 thousand bbl/d, which, if confirmed in the monthly data, would represent a 64% decrease compared to March 2011.

Refinery Utilization Rates React to Economics in 2011

The divergence of West Texas Intermediate (WTI) and Brent crude oil prices in 2011 affected refinery utilization in the United States, particularly in the East Coast (PADD 1) and Midwest (PADD 2) regions. Historically, refineries in these districts operated at 80-90% of their capacity. Changes in refining economics last year contributed to real contrasts in refinery utilization in some of the PADDs (see Overview chart).


graph of Average monthly refinery gross inputs and operable capacity, 2005 and 2011, as described in the article text
Source: U.S. Energy Information Administration, Refinery Utilization and Capacity.

 Some key findings by PADD include:
  • PADD 1. East Coast refining typically relies on imports of crude oil based on the Brent crude price, which, on average, increased to a $16-per-barrel premium over WTI spot prices in 2011. As a result, two East Coast refineries idled capacity due to poor economics, while another is considering selling or shutting down. PADD 1 utilization averaged only 68% of operable capacity in 2011, which includes the idle capacity of closed refineries. This utilization rate reflects both the drop in East Coast refining capacity and lower crude oil inputs.
  • PADD 2. Midwest refineries benefitted from supplies of less expensive crude oil coming from Canada and increased production in the Bakken formation. Thus, PADD 2 refineries averaged about 91% utilization in 2011, even with increased refining capacity. As a result, PADD 2 average crude oil inputs of nearly 3.4 million barrels per day were at the highest level since 2000.
  • PADD 3. Gulf Coast (PADD 3) continued capacity expansions as refineries upgraded infrastructure to maximize yields. Growing oil production in Texas and the Midwest contributed to increased inputs. The Gulf Coast refineries were able to use different types of crude oil to maximize production. Refineries in this region used cheaper sources of crude compared to the rest of the country.
  • PADDs 4 and 5. Refinery closures, outages, and a lack of access to less expensive crude oil reduced inputs in 2011 to refineries in PADDs 4 and 5 and helped drive down utilization rates.

EIA: Tight Oil, Gulf of Mexico Deepwater Drive Projected Increases in U.S. Crude Oil Production

 EIA's Annual Energy Outlook 2012 (AEO2012) early release reference case, providing updated projections for energy markets through 2035, projects increased domestic crude oil production driven by development of tight oil resources onshore and deepwater resources in the Gulf of Mexico. Tight oil refers to oil produced from shale, or other very low permeability rocks, with horizontal drilling and multi stage hydraulic fracturing technologies.

EIA projects that U.S. domestic crude oil production will increase from 5.5 million barrels per day in 2010 to 6.7 million barrels per day in 2020. Even with a projected decline after 2020, U.S. crude oil production projections remain above 6 million barrels per day through 2035.

The AEO2012 early Release Reference case projects that onshore tight oil production will increase significantly, reaching 1.3 million barrels per day in 2030 and remaining above 1 million barrels per day for the remainder of the projection. As with shale gas, the application of recent technology advances significantly increases the development of tight oil resources. Projections are made for selected tight oil plays; at this point, not all plays have been, or are being, evaluated for the application of emerging production technology.

The AEO2012 also projects that continued development of deepwater crude oil resources in the Gulf of Mexico will become an increasingly important component of domestic crude production. Drilling in the Gulf of Mexico Outer Continental Shelf has resumed following the lifting of the 2010 moratorium, but on a schedule moderated by a slower permitting process with increased environmental review. Production in the Gulf of Mexico fluctuates as new large development projects are brought on stream.

The AEO2012 Early Release Reference case assumes that lease options in the Pacific and Atlantic will eventually be opened, but significant production from those lease sales is projected to occur after 2035. Most of the Eastern Gulf of Mexico Planning Area remains under a Congressional drilling moratorium (the Gulf of Mexico Energy Security Act of 2006) until 2022.

U.S. refiners produced historically high volumes of distillate fuels (a category that includes both diesel fuel and heating oil) and motor gasoline in 2011. By fine-tuning their production mix, refineries consistently set record levels of distillate production, most recently topping 5 million barrels per day (bbl/d) for the weeks ending December 2 and December 16, 2011.

In 2011, weekly distillate production was above the five-year historical range 25 times, and ranked second highest an additional 19 times. Finished motor gasoline production was robust over the same period, but was slightly more in line with production volumes at comparable times of year since 2006.

Because of its chemical composition, crude oil run through a refinery typically yields roughly twice as much motor gasoline as distillate fuels. Therefore, regardless of economic or other incentives, refiners cannot completely stop making some finished petroleum products in favor of others. However, by adjusting downstream processes and the types of crude oil used, refineries can optimize production to fine-tune the balance of their finished products output. For much of 2011, refiners saw favorable margins and robust global demand for distillate fuels. In order to benefit from these trends, refineries:

  • Increased crude runs to maximize overall output. This explains why both motor gasoline and distillate fuels production levels are high relative to the five-year historical ranges.
  • Shifted production mix. This explains why the distillate fuels production levels exceeded historical ranges in more weeks than motor gasoline production did.

Since early October, the spot price for ultra-low-sulfur distillate fuel oil rose, while the spot price for motor gasoline (as measured by New York RBOB spot prices in the chart below) declined, widening the spread between these two petroleum product prices. On November 14, 2011, the spot price for ultra-low-sulfur distillate was nearly 65 cents per gallon higher than the spot price for RBOB. The spread between these product prices had not been more than 60 cents per gallon since November 2008.

Note: Ultra low sulfur distillate spot prices shown as New York ultra low sulfur distillate spot prices; motor gasoline prices reflect New York RBOB spot prices.

Along with high domestic prices, strong international markets for distillate fuel oils have spurred increased production. In the United States, refineries have typically optimized production for finished motor gasoline to meet high U.S. demand. European refineries, on the other hand, tend to produce higher percentages of distillate fuel oils, as diesel is used more broadly there for transportation.

 Due to crude supply disruptions to European refineries for much of this year, the region has imported more finished products. Weekly U.S. gross distillate export estimates (bound primarily for European and South American markets) were at record levels in the fourth quarter of 2011, topping more than 0.9 million bbl/d in October and November, and exceeding 1 million bbl/d in December.

Robust global distillate demand has led to a significant inventory draw, despite heightened U.S. production. From the end of September to the end of December, U.S. distillate inventories fell by more than 13 million barrels.

Beyond Natural Gas and Electricity.... More Than 10% of U.S. Homes Use Heating Oil or Propane

 While almost 85% of households in the United States heat with natural gas or electricity, more than 10% rely on heating oil or propane, according to the 2009 Residential Energy Consumption Survey. The shares of heating oil and propane are likely to remain small but significant in the U.S. residential heating mix. These fuels serve distinct populations—heating oil primarily serves households in the Northeast, while propane serves households in rural areas across the country.

Over 80% of homes that rely on heating oil for space heating are located in the Northeast. Also, heating oil is most commonly used in older homes, as about one-half of all homes that currently use heating oil were built before 1950. Generally, homes built since 1980 are not heated with heating oil, except in the Northeast. The survey data show that heating oil equipment is older than average but more likely to be regularly maintained than other types of heating equipment, providing some potential efficiency benefits.

Propane space heating has broader geographic distribution than heating oil, heating between 3% and 8% of households in every region. Across the country, propane use is most common in rural areas and mobile homes. About 83% of households with propane heating are located in rural areas that are typically beyond the reach of the natural gas distribution infrastructure. In the Midwest, the rural share is greater than 90%. Additionally, those living in mobile homes are twice as likely to heat with propane as those in other housing unit types. Propane is becoming more common in the Northeast; of homes built in this region between 2000 and 2009, equal amounts are heated with propane and heating oil.
