C&C Reservoirs latest EOR content release includes 23 EOR Evaluation Reports.
Highlights Include:
Coalinga Field (USA) – Four-Pattern Pilot – Continuous Steam Injection
Targeting the 3000 cP heavy oil, the pilot is expected to achieve an incremental recovery of >34% STOIIP with a steam utilization of 5.1 BW/BO. This success provided a basis for fieldwide expansion. Temperature surveys and PLTs proved to be useful tools for performance monitoring.
Magnus Field (UK) – Central Panel – Hydrocarbon WAG Miscible Flood
The project achieved gross and net hydrocarbon gas utilization of 9.8 MCF/BO and 3.5 MCF/BO respectively, with an expected incremental recovery of 10% STOIIP. Performance monitoring such as reservoir pressure measuring, tracer surveys, periodic Production Logging (PLT) and saturation logs, time lapse 4-D seismic, and reservoir simulation lay a basis for success.
Mangala Field (India) – Five-Spot Pattern Secondary EOR Pilot – Alkaline-Surfactant-Polymer (ASP) Flood
The highly successful pilot with an incremental recovery of 25.8% over polymer flood, resulted in an almost eightfold increase in oil production and a maximum water-cut drop of 70%, validating fieldwide expansion.
Means Field (USA) – San Andres Unit Project – CO₂ WAG Miscible Flood
Targeting the 6 cP moderate viscosity oil, the project successfully achieved an incremental recovery of 11% STOIIP with a CO₂ utilization of 15.5 MCF/BO. Comprehensive reservoir and simulation studies, infill drilling and pattern modification, along with organized and detailed surveillance program contributed to the overall success of this project.
Shuguang Field (China) – Du 66 Block Project – Cyclic Steam Injection
The technically and economically successful project targeted the 280-616 cP heavy oil with an expected incremental recovery of 18.1% STOIIP. Reservoir management measures including profile modification, re-perforation, sidetrack, selective injection/production, optimized injection schemes, contributed to the success of this project.
C&C Reservoirs’ EOR Evaluation Reports provide complete documentation on the EOR methods proven to be effective in improving field production performance, recording the lessons learned and best practices within the context of EOR over the lifespan of a field or reservoir.
Inside the DAKS EOR Module
DAKS™ Enhanced Oil Recovery (EOR) Module has been designed to optimize the screening of EOR methods to maximize recovery and address common industry challenges encountered when conducting EOR. Through the identification of applicable global analogues and best practices our users can understand key risks and uncertainties, using this information to identify the most appropriate methods for their assets.
