A Theoretical Optimization Method Applied in Oilfield Developed with Horizontal Patterns

Abstract:

Most current optimization methods could not take engineering and economical factors into account at the same time. A theoretical optimization method, which could obtain a simultaneous optimization of engineering and economy, has been proposed on horizontal injection-production patterns with net present value (NPV) and cumulative production as its target organisms. The theory of wave frontal movement has been utilized to limit the pattern scope and the pressure drawdown has its constraint from 0 to three quarters of the formation fracture pressure. The method is finally tried out in a certain field in Oman, and the optimized results are as below: for the face to face pattern and crisscross pattern, well spacing densities are 15/sq. mi. and 29/sq. mi., while the length of the wellbores are 3 300 feet and 2 600 feet. The results are pretty closed to the real data in situ and the simulation by reservoir numerical simulator.
