Data-Acquisition Optimization Maximizes Value of Mature Oil-Rim Reservoirs

摘要

The XamXung field offshore Sarawak,Malaysia,is a 47-year brownfield with thin remaining oil rims that have made field management challenging.The dynamic oil-rim movement has been a key subsurface uncertainty,particularly with the commencing of a redevelopment project.A reservoir,well,and facilities-management (RWFM) plan was implemented to optimize development decisions.This paper is a continuation of paper SPE174638 and outlines the outcome of the RWFM plan and the results'effect on development decisions such as infill well placement and gas/water injection-scheme optimization (Fig.1).Key decisions affected by the RWFM findings are highlighted in the complete paper.
