Analysis in North Sea supports high-grading IOR development options
Location: North Sea, UK
Objective: Waterflood and IOR simulation, Pilot Field
The Venture Production team has a portfolio of assets in the UK North Sea, including the Pilot Field, located in block 21/27a. The low API and viscous fluids in Pilot Field, combined with the isolated nature of the field and limited reserves base, create a unique set of development challenges.
Venture turned to RPS Knowledge Reservoir for reservoir simulation and development planning advice due to our experience in similar fields—Captain and Mariner—in the UK North Sea and in other viscous oil developments in both North and South America. The main focus of the study was to evaluate the potential for improved oil recovery (IOR) methods.
The Eclipse simulator was used to evaluate the incremental recovery and risks of polymer and thermal flooding over a conventional waterflood development. IOR subsurface risks for key reservoir uncertainties were quantified in terms of both oil barrels and net present value (NPV). Project management was achieved through regularly scheduled meetings and electronic data exchanges.
The study result enabled Venture Production to "high-grade" the IOR development options for better project decision making.
