Integrating Reservoir System Information for Cyclic Solvent Injection Process to Support Post-CHOPS Field Development

Heavy oil (high viscosity oil) is trapped underground. Cold heavy oil production with sand (CHOPS) is an enabling technology to extract heavy oil through wormholes forming around wellbore. There are thousands of CHOPS wells in Saskatchewan and Alberta with low primary oil recovery. Cyclic solvent injection (CSI) enhanced oil recovery process stands out as one of the most promising post-CHOPS methods. As the post CHOPS technology with cyclic solvent injection has been advanced into field operation stage, it is essential to focus on understanding and implementing the information embedded in field data of well performance using CSI. This project could identify the highly productive and less productive CSI wells and provide an optimal operation strategy to improve the field post-CHOPS CSI process.
