Utilization of Carbon and other Energy Gases - Geologic Research and Assessments

Carbon Dioxide (CO2) is utilized by industry to enhance oil recovery. Subsurface CO2 storage could significantly impact reduction of CO2 emissions to the atmosphere, but the economics and potential risks associated with the practice must be understood before implementing extensive programs or regulations. Utilization of other energy-related gases such as helium (He), if separated and concentrated...

Quantities of Water Associated with Oil and Gas Thumbnail

Quantities of water associated with oil and gas development

Work in this task of the Oil and Gas Waters Project focuses on quantifying the water used during hydrocarbon development and the water produced along with oil and gas. Hydraulic fracturing is an integral part of oil and gas development in many areas, and water use for this purpose has increased considerably in the last decade. Water produced from petroleum reservoirs includes hydraulic fracturing...
