Geologic sequestration of CO2 in depleted oil reservoirs, while a complex issue, is thought to be a safe and effective carbon management strategy. This paper provides an overview of a NETLsponsored R&D project to predict and monitor the migration and ultimate fate of CO2 after being injected into a depleted oil reservoir as part of a micropilot scale field experiment. The Queen Formation sandstone, located in the West Pearl Queen field in SE NM, was identified as the CO2 injection site for this project. Core samples of this formation were obtained for lithologic analysis and laboratory experimentation. Preliminary flow simulations were run using this data and suggest that at least 2000 tons of CO2 can be injected...

Bedded trona (Na2CO=-NaHCO=.214,0) in the lacustrine Green River Formation of Eocene age in the Green River Basin, southwest Wyomin~ constitutes the largest known resource of natural sodium carbonate in the world, in this study, 116 gigatons (Gt) of trona ore are estimated to be present in 22 beds, ranging from 1.2 to 11 meters (m) in thickness. Of this total, 69 Gt of trona ore are estimated to be in beds containing less than 2 percent halite and 47 Gt in beds containing 2 or more percent halite. These 22 beds underlie areas of about 130 to more than 2,000 km: at depths ranging from about 200 m to more than 900 m below the surface. The total resource of trona ore in the basin for which drilling Information is available...
