Reservoir stochastic modeling for the Shuanghe Oil Field, Henan

A high-resolution 3-D reservoir model is constructed using the stochastic modeling technique for the Shuanghe Oil Field, Henan in order to provide reliable data for optimizing exploration plans. The modeling technique is base on the recognition of 11 types of sedimentary facies and 6 facies associations, division of sedimentary microfacies, and division and correlation of base level cycles with the aid of high-resolution sequence stratigraphic theory. The 3-D microfacies model is formulated by using the truncating Gauss simulation method, and the 3-D model is suggested for the porosity and permeability by using sequence Gauss simulation method. Finally the reservoir model is upscaled for reservoir numerical simulation.
