Sequestration of carbon dioxide (CO2) in depleted oil reservoirs is one of the viable options for carbon management. This paper describes the preliminary modeling and flow simulation part of a DOE sponsored CO2 sequestration project. The main objective of the project is to understand the feasibility of long term sequestration of CO2 in a depleted oil reservoir through a field demonstration experiment. Before the actual CO2 injection begins, it was necessary to determine feasibility of injection. Advanced geologic modeling and flow simulation techniques were used to develop a model for the proposed target interval. A geologic model was developed using data available from well logs and cores. Subsequently, porous...

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...
