Reservoir: Quantifying By-Passed Oil Reserves in the Apache Forties Field
The Forties field is the largest discovery in the UK North Sea. It still ranks in the top ten in liquid hydrocarbons production and remaining liquid hydrocarbon reserves despite after having produced 2.5 billion barrels from its 5 billion barrels original oil in place. Apache Corp acquired the field during early 2003 with anticipated 2003 gross production of about 46,000 barrels of oil per day. Production rates have subsequently increased by about 50% and remaining reserves by over 20% during the past two years due to successful targeting of by-passed oil through integrated study.
This presentation will discuss difficulties encountered in building an integrated multi-million cell streamline reservoir model for this geologically complex field, history matching challenges, and the coupling of streamline model results with seismic imaging to identify and rank infill target locations. It will also highlight the integration of a coupled material balance and pipeline steady-state solution network results with a streamline predictive model to make first-order water flood optimization runs.
