A Novel Approach for the Evaluation of Oil and Gas Well Performances in Multiwell Reservoir Systems

摘要

The current methods for estimating Oil- or Gas-In-Place and Reservoir Flow Capacity using dynamic data (pressure and/or rate) assume a single well in a closed system (or single well with constant pressure or prescribed influx at the outer boundary). In many cases a well produces in association with other wells in the same reservoir - and unless all wells are produced at the same constant rate or the same constant bottomhole flowing pressure, non-uniform drainage systems will form during boundary-dominated flow conditions.
