Permian Basin expected to drive fourth quarter U.S crude oil production increases
In its Short-Term Energy Outlook (STEO) update released this week, EIA forecasts that U.S crude oil production will average 9.4 million barrels per day (b/d) in the second half of 2017, 340,000 b/d more than in the first half of 2017.
EIA’s close monitoring of current rig activity in several producing regions shows continued production growth from tight-oil formations, such as shale in the Permian region, driving overall production increases (Figure 1).
The STEO projects that the most significant production growth in the second half of 2017 will be in the Permian region. Permian production is forecast to grow to 2.6 million b/d in the second half of 2017, a 260,000 b/d increase from the first half of 2017. Production in the Permian continues to increase, in part as a result of West Texas Intermediate (WTI) crude oil average monthly prices that have remained higher than $45 per barrel (b) since the second half of 2016.
Extending across western Texas and southeastern New Mexico, the Permian region has developed into one of the more active drilling regions in the United States because its large geographic size and favorable geology contain many prolific tight formations such as the Wolfcamp, Spraberry, and Bonespring. Increases in proppant intensity, lateral lengths, and changes to slick-water completions are also among the factors that have allowed the Permian to remain one of the most economic regions for oil production despite the low-oil-price environment. WTI spot prices averaged $50/b in the first half of 2017, spurring deployment of more rigs to the Permian, which rose steadily from 276 rigs in January to 380 rigs in September. The STEO projects that the Permian region rig count will continue to grow from an average of 341 rigs in 2017 to 371 rigs in 2018, and the WTI price is forecast to average $49/b for the second half of 2017 and $51/b in 2018.
The STEO forecasts Niobrara and Anadarko production to grow by 75,000 b/d and 42,000 b/d, respectively, averaging 500,000 b/d and 460,000 b/d, respectively, for the second half of 2017. This growth makes these two regions the second- and third-largest contributors to the STEO’s projected growth between the first and second half of 2017. Production in the Niobrara and Anadarko regions has grown continuously since January 2017 in response to increasing rig activity and a monthly WTI price range from $45/b to $53/b during the year. With an expectation that prices will continue to be near this range, rig activity and production are expected to continue to grow.
In the STEO forecast, the Bakken region is expected to maintain production at slightly less than 1.1 million b/d through 2017, increasing by 31,000 b/d between the first and second half of the year. The Bakken region predominately spans the Williston Basin, which contains the Bakken and the Three Forks formations. Although the Bakken region is large in geographic size (23 million acres), it contains fewer identified prolific formations than the Permian. In addition, operators in this region are affected by winter weather and have greater transportation constraints in moving oil to refineries and markets. Rigs in the Bakken region grew from 35 in January to 44 in May of this year, increasing further to 51 in September.
The STEO forecasts production in the Eagle Ford region to remain relatively flat in the second half of 2017 at 1.2 million b/d, a 5,000 b/d increase from the first half of 2017. Compared with the Permian, the Eagle Ford region has a significantly smaller geographic area with fewer prolific stacked formations and fewer opportunities to drill. Rigs in the Eagle Ford region grew from 57 to 98 from January through May of this year, but declined to 83 in September, in part as a result of a lagged response to lower WTI prices in the second quarter of 2017. More recently, the Eagle Ford region experienced temporary outages in production and rig activity in August and September because of Hurricane Harvey.
EIA expects Alaska production to remain relatively flat, averaging 460,000 b/d in the second half of 2017, a 22,000 b/d decrease from the first half of 2017, because of seasonal maintenance on the Trans-Alaska Pipeline System during the third quarter.
Production in the rest of the United States is expected to remain fairly constant, with relatively modest production declines in California (30,000 b/d) and the Federal Offshore Gulf of Mexico (7,000 b/d) in the second half of 2017.
In the Lower 48 states, observed rig counts typically follow changes in the WTI price with an approximate four-month lag (Figure 2). In addition to responding to the WTI price, rig counts are related to cash flow and profitability. If returns are positive at a given price level, an operator could choose to add rigs. In that scenario, prices do not have to continually rise to support increases in rig counts. For most predominately tight-oil regions to see continued growth in production, rig activity must continue to increase because of the well dynamics, which on average have high initial production rates but very fast declines (e.g., 60% over the first 12 months of production). However, with the number of rigs continuing to increase, especially in the Permian, EIA has assessed that new wells are being drilled at a pace sufficient to maintain and increase production levels. If that trend changes, EIA will continue its process of adjusting its forecast in regular monthly STEO updates.
EIA models oil production monthly in the STEO at the state and regional levels. The STEO forecast is based on recent trends in drilling and production and on anticipated future changes, driven largely by the WTI price. EIA evaluates past production trends on a well-by-well basis for all production documented since 2014 and uses that history to estimate future well performance and decline rates at the state and regional levels.
As indicated above, EIA has observed that changes in the WTI price affect the number of active drilling rigs within about four months. Changes in the number of active rigs lead to changes in production volumes within about two months. Consequently, the STEO oil production forecast is based on the historical observation that changes in production volumes typically occur about six months after a change in the price of crude oil. The forecast is also influenced by estimates of cash flow and production costs, which vary by region and over time. In addition, the STEO makes assumptions regarding how the inventory of drilled but uncompleted wells responds to price and how that response affects production at the state and regional levels.
All historical production data are benchmarked monthly to the EIA-914 survey data and to EIA’s Petroleum Supply Monthly (PSM) estimates at the state level. The October STEO forecast for oil production is benchmarked to the PSM data for July 2017.
Since it started in 2016, the Dallas Fed Energy Survey quarterly business indicator of the share of exploration and production firms that think oil production will increase or decrease has moved consistently with EIA’s 914 survey of oil production. Consistent with the updated STEO forecast for U.S. oil production, the recently released 2017 third-quarter report from the Dallas Fed survey (July–September) shows expectations of an increase in oil production in Texas, New Mexico, and northern Louisiana from an index of 10.2 in the second quarter to 19.3 in the third quarter.
Forecasting crude oil production is a dynamic process because of many uncertainties. Not all operators respond to price movements at the same time, which leads to uncertainty in the timing and degree of change in the production trend. Constantly evolving drilling practices within the industry, changes in well performance, pipeline infrastructure, and weather events can also have significant influence on the short-term outlook for crude oil production in the Lower 48 states. Production estimates have shifted (and are likely to continue to shift) as new geological information is gained, long-term well productivity is observed, and technological advances and better operational practices improve well productivity and reduce costs. Potential changes in market dynamics, such as recent indications that investors may require companies to focus more on returns and less on production growth, also add uncertainty to the pace and level of future production.

In 2019, consumption of renewable energy in the United States grew for the fourth year in a row, reaching a record 11.5 quadrillion British thermal units (Btu), or 11% of total U.S. energy consumption. The U.S. Energy Information Administration’s (EIA) new U.S. renewable energy consumption by source and sector chart published in the Monthly Energy Review shows how much renewable energy by source is consumed in each sector.
In its Monthly Energy Review, EIA converts sources of energy to common units of heat, called British thermal units (Btu), to compare different types of energy that are more commonly measured in units that are not directly comparable, such as gallons of biofuels compared with kilowatthours of wind energy. EIA uses a fossil fuel equivalence to calculate primary energy consumption of noncombustible renewables such as wind, hydro, solar, and geothermal.

Wind energy in the United States is almost exclusively used by wind-powered turbines to generate electricity in the electric power sector, and it accounted for about 24% of U.S. renewable energy consumption in 2019. Wind surpassed hydroelectricity to become the most-consumed source of renewable energy on an annual basis in 2019.
Wood and waste energy, including wood, wood pellets, and biomass waste from landfills, accounted for about 24% of U.S. renewable energy use in 2019. Industrial, commercial, and electric power facilities use wood and waste as fuel to generate electricity, to produce heat, and to manufacture goods. About 2% of U.S. households used wood as their primary source of heat in 2019.
Hydroelectric power is almost exclusively used by water-powered turbines to generate electricity in the electric power sector and accounted for about 22% of U.S. renewable energy consumption in 2019. U.S. hydropower consumption has remained relatively consistent since the 1960s, but it fluctuates with seasonal rainfall and drought conditions.
Biofuels, including fuel ethanol, biodiesel, and other renewable fuels, accounted for about 20% of U.S. renewable energy consumption in 2019. Biofuels usually are blended with petroleum-based motor gasoline and diesel and are consumed as liquid fuels in automobiles. Industrial consumption of biofuels accounts for about 36% of U.S. biofuel energy consumption.
Solar energy, consumed to generate electricity or directly as heat, accounted for about 9% of U.S. renewable energy consumption in 2019 and had the largest percentage growth among renewable sources in 2019. Solar photovoltaic (PV) cells, including rooftop panels, and solar thermal power plants use sunlight to generate electricity. Some residential and commercial buildings heat with solar heating systems.

Based on the U.S. Energy Information Administration's (EIA) annual survey of electric generators, natural gas-fired generators accounted for 43% of operating U.S. electricity generating capacity in 2019. These natural gas-fired generators provided 39% of electricity generation in 2019, more than any other source. Most of the natural gas-fired capacity added in recent decades uses combined-cycle technology, which surpassed coal-fired generators in 2018 to become the technology with the most electricity generating capacity in the United States.
Technological improvements have led to improved efficiency of natural gas generators since the mid-1980s, when combined-cycle plants began replacing older, less efficient steam turbines. For steam turbines, boilers combust fuel to generate steam that drives a turbine to generate electricity. Combustion turbines use a fuel-air mixture to spin a gas turbine. Combined-cycle units, as their name implies, combine these technologies: a fuel-air mixture spins gas turbines to generate electricity, and the excess heat from the gas turbine is used to generate steam for a steam turbine that generates additional electricity.
Combined-cycle generators generally operate for extended periods; combustion turbines and steam turbines are typically only used at times of peak load. Relatively few steam turbines have been installed since the late 1970s, and many steam turbines have been retired in recent years.

Not only are combined-cycle systems more efficient than steam or combustion turbines alone, the combined-cycle systems installed more recently are more efficient than the combined-cycle units installed more than a decade ago. These changes in efficiency have reduced the amount of natural gas needed to produce the same amount of electricity. Combined-cycle generators consume 80% of the natural gas used to generate electric power but provide 85% of total natural gas-fired electricity.

Every U.S. state, except Vermont and Hawaii, has at least one utility-scale natural gas electric power plant. Texas, Florida, and California—the three states with the most electricity consumption in 2019—each have more than 35 gigawatts of natural gas-fired capacity. In many states, the majority of this capacity is combined-cycle technology, but 44% of New York’s natural gas capacity is steam turbines and 67% of Illinois’s natural gas capacity is combustion turbines.
Countries that are not members of the Organization for Economic Cooperation and Development (OECD) in Asia, including China and India, and in Africa are home to more than two-thirds of the world population. These regions accounted for 44% of primary energy consumed by the electric sector in 2019, and the U.S. Energy Information Administration (EIA) projected they will reach 56% by 2050 in the Reference case in the International Energy Outlook 2019 (IEO2019). Changes in these economies significantly affect global energy markets.
Today, EIA is releasing its International Energy Outlook 2020 (IEO2020), which analyzes generating technology, fuel price, and infrastructure uncertainty in the electricity markets of Africa, Asia, and India. A related webcast presentation will begin this morning at 9:00 a.m. Eastern Time from the Center for Strategic and International Studies.

IEO2020 focuses on the electricity sector, which consumes a growing share of the world’s primary energy. The makeup of the electricity sector is changing rapidly. The use of cost-efficient wind and solar technologies is increasing, and, in many regions of the world, use of lower-cost liquefied natural gas is also increasing. In IEO2019, EIA projected renewables to rise from about 20% of total energy consumed for electricity generation in 2010 to the largest single energy source by 2050.
The following are some key findings of IEO2020:
IEO2020 builds on the Reference case presented in IEO2019. The models, economic assumptions, and input oil prices from the IEO2019 Reference case largely remained unchanged, but EIA adjusted specific elements or assumptions to explore areas of uncertainty such as the rapid growth of renewable energy.
Because IEO2020 is based on the IEO2019 modeling platform and because it focuses on long-term electricity market dynamics, it does not include the impacts of COVID-19 and related mitigation efforts. The Annual Energy Outlook 2021 (AEO2021) and IEO2021 will both feature analyses of the impact of COVID-19 mitigation efforts on energy markets.
With the IEO2020 release, EIA is publishing new Plain Language documentation of EIA’s World Energy Projection System (WEPS), the modeling system that EIA uses to produce IEO projections. EIA’s new Handbook of Energy Modeling Methods includes sections on most WEPS components, and EIA will release more sections in the coming months.
