Natural CO2 Resources

For the National Energy Technology Laboratory, in an effort to remove uncertainty surrounding the need for CO2 for EOR from advanced fossil-fuel platforms that exists due to the lack of a comprehensive U.S.-based resource estimate of CO2 available from subsurface sources, Enegis LLC conducted a screening study to characterize the subsurface sources of CO2 as an initial step to assess the impacts to national energy strategy. Both discovered and undiscovered resources were evaluated

Biomass Energy Analytical Model

The federal government is the largest consumer of electricity in the United States. In an effort to mitigate carbon emissions, the Department of Energy (DOE), Federal Energy Management Program (FEMP) has a mandate to maximize the amount of power generated by biomass that is used by the federal government.

Biomass Land Cover

Beginning in 2009, Enegis developed a quantitative geoanalytical model to assess the available biomass in the Lower 48 states. The Biomass Energy Analytical Model (BEAM) was conceived to analyze the use of biomass for federal power generation. The BEAM was formed for the National Energy Technology Laboratory (NETL) under the guidance of a steering committee comprising NETL officials.

Biomass Land Cover

The BEAM 's overall objectives are to quantify and classify the available biomass resource and to model its transport, storage, and usage on local and regional scales. Central to the BEAM is a 30-meter resolution land cover dataset and detailed transportation infrastructure and include full-cycle costs. The model is ideally suited for site planning and optimization as biomass markets emerge. The BEAM can be readily adapted for a number of resources and scenarios beyond those originally conceived, and has already been used to model biomass to liquids and land-use change scenarios involving growing switchgrass on existing farmland. Please contact us if you are interested in assessing biomass supply and cost using BEAM.

Carbon Capture & Sequestration

Coal-fired power plants supply almost 50 percent of electricity needs in the United States. Given the importance of coal to power generation in the United States examination of the costs and practicability for retrofit of existing pulverized coal power plants with CO2 capture technology is an essential. To help elucidate this issue, Enegis worked with the National Energy Technology Laboratory (NETL) to individually examine the population of pulverized coal-fired power plants to determine costs and estimate space availability for retrofit. The effort is designed to assess coal-fired power plants in the U.S. relative to the cost and feasibility for retrofit with CO2 capture technology.

Carbon Capture

The effort comprised the development of a database and quantitative geoanalytical model. The model operates on the population of coal-fired power units in the U.S. Each unit in the analysis is examined individually to develop cost curves for a levelized cost of electricity, carbon capture costs, and avoided CO2 cost. This work was sponsored by the DOE NETL.

Geologic Sequestration of CO2

The International Performance Assessment Centre for geologic storage of Carbon Dioxide (IPAC-CO2), is an environmental, non-government organization created to fill a gap in the understanding and assessment of risk and performance in the Carbon Capture and Storage (CCS) chain.  IPAC-CO2 was was established in 2009 with funding from the Government of Saskatchewan, the University of Regina, Royal Dutch Shell and the Government of Canada.

Enegis is currently providing geospatial and analytical support to the IPAC-CO2 in their investigation of reported anamolies surrounding CO2 injected at Encana’s Weyburn Enhanced Oil Recovery project in southern Saskatchewan. Enegis will also assist IPAC-CO2's investigation of the risks associated with geologic sequestration of CO2 for North America.

Energy Policy Act (EPAct) Geothermal Royalties Streamlining for Federal Leases

The Energy Policy Act of 2005 (EPAct) required that the Secretary of the Interior issue final regulations concerning geothermal leasing, “to achieve the same level of royalty revenues over a 10-year period as the regulation in effect on the date of enactment of this subsection [2005].” Enegis performed an economic analysis of electricity royalties of geothermal resources and power generation in the western U.S. relative to federal royalty revenues for the Bureau of Land Management (BLM). The analysis is based upon a BLM-reviewed specialized resource and economic model called the Geothermal Royalty Evaluation Model (GREM). Numerous scenarios were run incorporating proximity to critical infrastructure such as roads and powerlines, variable electricity prices and demands, and the proximity and suitable geologic geothermal resources. Given the demands of the rulemaking period, this effort was conducted in a short time frame and was used to help establish the basis for the federal government’s geothermal royalty rate.

Energy Policy & Conservation Act (EPCA) Inventory

The Energy Policy and Conservation Act (EPCA) of 2005 called for the Secretary of the Interior, in consultation with the DOE and other agencies, to conduct and inventory of all federal onshore oil and gas resources and qualitatively assess restrictions and impediments to their development. Enegis staff performed this multi-year effort.


In the course of the project, we interacted with over one hundred and twenty five BLM and Forest Service (FS) offices and the U.S. Geological Survey (USGS) to interview field experts for input into parameters for the analysis and collect resource, land, GIS and other data. Source data included many thousand feature classes representing Federal surface and mineral estate, land use plan leasing stipulations, and oil and gas resources. Using a complex geoanalytical model that examines over 13 million discrete polygons, the inventory examined the approximately 3,000 different lease stipulations being applied by the land managing agencies in the areas analyzed. This analysis of constraints to development centers on two factors that affect access to oil and gas resources on Federal lands: (1) whether the lands are "open" or "closed" to leasing, and (2) the degree of access afforded by lease stipulations and other conditions on "open" lands. The model addresses the issues of overlapping stipulation geometries, exceptions, waivers, and modifications granted to stipulations, the ability of industry to directionally drill under areas prohibiting surface occupancy, and the application of Conditions of Approval.

The latest EPCA Inventory presents an assessment of the access issues for the development of oil and gas resources on Federal lands. EPCA assessed 18 basins from Alaska to Florida, totaling 279 million acres of Federal land.


Using our model, Federal land managers are able to more clearly balance environmental concerns relative to access to resources thereby streamlining U.S. energy policy. The Inventory was conducted in three phases over a multi-year period and has resulted in multiple reports to Congress. The work was sponsored by the Department of the Interior, Bureau of Land Management.

Energy Policy Act (EPAct) Coal Inventory

Enegis conducted this analysis to assess accessibility to coal resources in the Powder River Basin of Wyoming and Montana. The effort involved creating a geoanalytical model to integrate and analyze data representing coal thickness and depth, land use planning management decisions, and federal surface and coal mineral estate. This analysis was complex due to the three-dimensional nature of coal resources, the technology available to the coal industry, and the large number of complex environmental impacts of coal mining. The study assists federal land managers to better address access to coal resources relative to protecting sensitive environmental values. The analysis was conducted under a severe deadline and resulted in a report to Congress.
