Clive Oil Field

The Clive Oil Field CO₂-EOR project is located in central Alberta, Canada, within the Western Canada Sedimentary Basin (WCSB). The field produces primarily from Devonian-age carbonate reservoirs, including reefal and platform limestone intervals characterized by strong structural and stratigraphic trapping. After primary production and secondary waterflooding, the field transitioned to tertiary recovery using miscible CO₂ injection to improve recovery efficiency from mature carbonate reservoirs. CO₂ is supplied via regional pipeline infrastructure and injected through pattern-based flood designs, commonly incorporating water-alternating-gas (WAG) cycles to manage mobility and improve sweep efficiency within heterogeneous carbonate facies. Produced fluids are processed at surface facilities where CO₂ is separated, recompressed, and recycled for reinjection, while retained volumes contribute to long-term geologic storage through structural trapping, residual trapping, and dissolution within formation fluids. The Clive project represents a Western Canadian example of integrating CO₂ utilization with long-term storage, leveraging mature Devonian carbonate reservoirs with established sealing formations and existing oilfield infrastructure.
