Optimization of Gas Condensate Reservoir Using Compositional Reservoir Simulator

摘要

In the past years several authors have fielded many questions from companies, both domestic and international concerning gas condensate reservoirs. It appears that gas condensates are becoming more important throughout the world. Also, many international petroleum societies are beginning to have conferences specifically oriented to gas condensate reservoirs and discussing all parameters germane to such systems. Based on this increased interest, we took up the challenge to study gas condensate reservoir, and in this paper we have highlighted the best production method and future exploitation plans for a gas condensate reservoir using a compositional simulator to justify the application of WAG, pressure depletion and gas cycling technique aimed for optimum reservoir and production performance. The results show a remarkable improvement of condensate recovery after an optimization job was done for different scenario. Also, this paper emphasize on a major associated problem with producing gas condensate reservoir, which is the effect of retrograde condensation that results to condensate (blockage) banking, thus causing a reduction in reservoir and well performance.
