摘　　要：Reservoir simulation is known as perhaps the most widely used,accurate,and reliable method for field development in the petroleum industry.An integral part of a reliable reservoir simulation process is to consider robust and rigorous tuned EOS models.Traditionally,EOS models are tuned iteratively through arduous workflows against experimental PVT data.However,this comes with a number of drawbacks such as forcingly using weight factors,which upon alteration adversely affects the optimization process.The objective of the current work is thus to introduce an auto-tune PVT matching tool using NSGA-II multi-objective optimization.In order to illustrate the robustness of the presented technique,three different PVT samples are used,including two black-oil and one gas condensate sample.We utilize PengRobinson EOS during all the manual and auto-tuning processes.Comparison of auto-tuned EOS-generated results with those of experimental and computed statistical error values for these samples clearly show that the proposed method is robust.In addition,the proposed method,contrary to the manual matching process,provides the engineer with several matched solutions,which allows them to select a match based on the engineering background to be best amenable to the problem at hand.In addition,the proposed technique is fast,and can output several solutions within less time compared to the traditional manual matching method.
