The Importance of Baseload Power Renewal
Contact: Peter C. Balash, PhD
Coal plants have traditionally provided reliable and affordable baseload power generation, and extensive coal retirements are prompting debate on potential grid impacts. This analysis examines how current forecasts may be understating risks: both under-projecting electricity demand growth and expecting an aging fleet to operate at historically high utilization rates. Potential generation and capacity shortfalls due to a timing mismatch between unit retirements and unit additions are discussed. Also reported are operational conditions of retiring units January 2014; actual gas prices compared to projections; and price volatility risks of shifting to gas. View as "slideshow" for best effect
CO2-EOR Offshore Resource Assessment
Contact: Evelyn Dale
The Gulf of Mexico accounts for about 20 percent of total domestic crude oil production. Since reaching a peak of 1.54 million barrels a day in 2003, Gulf of Mexico’s OCS oil production has declined to 1.23 MMB/D, as of mid-2013. While there is optimism that new discoveries in the deep and ultra-deep waters of the GOM OCS will reverse this decline, another option seems to offer even more promise -- the application of CO2 enhanced oil recovery.
Near-Term Projections of CO2 Utilization for Enhanced Oil Recovery
Contact: Chris Nichols
In 2013 a total of 113 CO2-EOR projects inject 3.1 billion cubic feet per day (Bcfd) (60 million metric tons (MMmt) per year) of CO2 for enhanced oil recovery in the United States. The associated crude oil production in 2012 was 282,000 barrels per day. Based on the increased volumes of CO2 supplies, the completion of major CO2 pipelines, and the announced new, large-scale CO2-EOR floods, production of crude oil from CO2-EOR floods is forecast to grow significantly, reaching 615,000 barrels per day from at least 124 active CO2 floods by year 2020. While the Permian Basin remains the largest CO2-EOR oil producer, much of the growth occurs in the Gulf Coast, the Rockies, and the Mid-Continent.
Next Generation CO2 EOR
Presentation slide deck from the CO2 Utilization Congress. Draws on recent NETL analyses and other sources to present: (1) a primer on CO2 EOR, (2) an overview of the current status of CO2 EOR in North America, (3) a description of next generation CO2 EOR technology, and (4) an estimate of the size of the resource in the United States.
Subsurface Sources of CO2 in the Contiguous United States. Volume 1: Discovered Reservoirs
Twenty-one CO2 fields in the contiguous states contain an estimated 311 Tcf of CO2 gas-initially-in-place (GIIP). Of that, 168 Tcf (54 percent) is estimated to be accessible and technically recoverable. The estimated economically recoverable resource (ERR) is 96.4 Tcf, based on a CO2 price of 1.06 $/mcf ($20/tonne) at the field gate. Cumulative production to date is 18.9 Tcf, leaving 77.5 Tcf remaining or net ERR. The Big Piney-LaBarge field in Wyoming contains an estimated net ERR of 52 Tcf, 67 percent of the total for the United States. The remaining ERR in reservoirs that feed into the Permian Basin and Gulf Coast is on the order of 10-20 years of supply.
Subsurface Sources of CO2 in the United States. Volume II: Exploration of CO2 Systems
A study of the genesis and tectonic setting of subsurface CO2 systems in the United States indicates that undiscovered CO2 reservoirs could contribute materially to CO2 supply for enhanced oil recovery. Five geographic areas are estimated to contain 42 Tcf of risked technically recoverable CO2 resource (TRR). Two lead areas near the Permian Basin, Val Verde and San Juan, contain 34 Tcf CO2 risked TRR, an amount roughly equivalent to the remaining TRR in discovered reservoirs that are currently supplying the region. The number of lead areas studied was limited and the aggregate TRR estimates are not comprehensive.

LCA and the U.S. Natural Gas Resource
Contact: Timothy J. Skone
From a life cycle perspective, baseload power is NETL's preferred basis for comparing energy sources. For fossil energy systems, the emissions from power plants account for the majority of greenhouse gas (GHG) emissions. However, focusing on the activities that precede the power plant is still necessary in order to identify near-term opportunities for GHG emission reductions. NETL's upstream natural gas model allows detailed modeling of the extraction, processing, and pipeline transmission of natural gas. This model can identify key contributors to the GHG emissions from the natural gas supply chain, and has parameters that can be used to assess opportunities for reducing GHG emissions. The model shows that current domestic natural gas extraction, processing, and pipeline technologies leak 1.2% of the methane that is extracted at the wellhead. Improved practices, such as those in the latest New Source Performance Standards (NSPS), can reduce this upstream methane leakage rate. From a life cycle perspective (1 MWh of delivered electricity), power production from natural gas has lower GHG emissions than power produced from coal. There are several methods and technology combinations that can be used for determining how high the upstream natural gas methane leakage rate has to be in order for the life cycle GHG emissions from natural gas power to equal those from coal power. Ongoing research is developing data that will improve the accuracy of NETL's upstream natural gas model.

CO2 STORAGE AND UTILIZATION NEAR MINGO COUNTY, WEST VIRGINIA
Contact: DiPietro, Phil
Six oil fields within 100 miles of the planned coal-to-liquids facility in Mingo County were found to be prospective for miscible CO2-EOR. Four of the oil fields fall along a straight line and could, in concept, be developed sequentially along a single CO2 pipeline. The total demand for purchased CO2 from these four fields is estimated to be 47 million metric tons (890 Bcf) over 20 years. Four saline formations within Mingo County could accommodate 50 million metric tons of CO2 (accounts for uncertainty and a “buffer zone”). The combined storage capacity – EOR within 100 miles of Mingo County and saline within Mingo County – can accommodate 3 million metric tons per year of vented CO2 for over 30 years Conclusion: there is enough potential for CO2 utilization and storage that a next level of study is a reasonable course.
An In-Depth Look at "Next Generation" CO2 EOR Technology
This analysis takes a more in-depth look at the "Next Generation" CO2-EOR concept and defines distinct areas of technology development that comprise it. The CO2-PROPHET model is used to simulate the application of the four main "Next Generation" technologies to a database of 1,824 Lower-48 onshore oil reservoirs, first applied singularly and then in combination. The simulations indicate significant synergy when the technology areas are applied jointly. The results show that "Next Generation" CO2 EOR can provide positive impacts – 2 MMbpd of domestic oil production for 50 years - but it is not free. "Next Generation" CO2-EOR designs require capital outlays two times higher than current best practices.

A Forecast of Crude Oil Production from Carbon Dioxide Enhanced Oil Recovery in the United States through 2018
CO2 supply for enhanced oil recovery operations in the United States is expected to increase 64% between 2012 and 2018, from 3.3 BCFd to 5.4 BCFd. The CO2 utilization rate (URNet the amount of CO2 supplied per incremental barrel of crude oil produced) can be used to estimate crude oil production based on CO2 supply rate. Based on compiled historical data we estimate the following regional CO2 Utilization rates: Permian basin, 8,500 scf/bbl, Rocky mountain, 8,000 scf/bbl, Gulf Coast, 25,000 scf/bbl. Applying these rates to the regional forecast for CO2 supply we forecast production from CO2 EOR in the United States in 2018 will be 500,000 bpd.
North American CO2 Supply and Developments
In 2013 carbon dioxide enhanced oil recovery (CO2 EOR) operations in North America purchased 3.4 billion standard cubic feet of CO2 and produced 318,000 barrels per day of crude oil. The average CO2 utilization rate was 9,200 scf/bbl in the Permian Basin, 8,800 scf/bbl in the Rocky Mountain region and 26,000 scf/bbl in the Gulf Coast region. Based on expected regional growth in CO2 supply and expected trends in average CO2 utilization rates, crude oil production from CO2 EOR in North America is forecast to be 590,000 bpd in 2018.

Improving Domestic Energy Security and Lowering CO2 Emissions with “Next Generation” CO2-Enhanced Oil Recovery (CO2-EOR)
NETL has revised its national resource assessment for carbon dioxide enhanced oil recovery (CO2 EOR). Under a current technology scenario, 1,200 reservoirs in the lower 48 states are amenable to CO2 EOR. At an assumed crude oil market price of $85 per barrel, these reservoirs represent 24 billion barrels of economic reserves. Under a next generation scenario the economic supply from CO2 EOR increases to 60 billion barrels. The resource assessment unveils a strong dependence on CO2 capture technology, as the equivalent of 60 - 90 GW of coal-fired plants with 90% capture will be needed to supply EOR floods.
Life Cycle Greenhouse Gas Analysis of Natural Gas Extraction & Delivery in the United States
On May 12, 2011 NETL provided the following presentation at the Cornell University lecture series on unconventional natural gas development. The presentation summarizes the life cycle analysis (LCA) greenhouse gas (GHG) research on natural gas extraction and delivery in the United States (on a lb CO2e/MMBtu basis) and a comparison of the life cycle GHG profiles of average natural gas and coal-fired power production and delivery to an end-user (lb CO2e/MWh basis). Specifically, the presentation details seven natural gas profiles: onshore conventional gas, associated gas, offshore gas, tight sands (gas), shale gas (based on Barnett Shale), coal bed methane gas, and the year 2009 domestic average mix. Each natural gas source is upgraded in a gas processing plant, compressed, and delivered to a large end-user (e.g., power plant).

An Assessment of Gate-to-Gate Environmental Life Cycle Performance of Water-Alternating-Gas CO2-Enhanced Oil Recovery in the Permian Basin
Contact: Robert Dilmore
CO2-enhanced oil recovery (CO2-EOR) stimulates oil production while storing a portion of the injected CO2. Life cycle assessment was performed for three CO2-EOR scenarios to estimate the "gate-to-gate" greenhouse gas (GHG) emissions associated with water-alternating-gas injection in a typical Permian Basin reservoir. Current CO2-EOR "best practices" generate greenhouse gas (GHG) emissions of 71 kg CO2 equivalents (CO2E) per barrel of oil extracted - approximately three times greater than GHG emissions for the average barrel of domestic oil extracted in 2005.
