Abstract

Estimation of petrophysical parameters of hydrocarbon reservoirs such as porosity and PERMEABILITY using 3D seismic data is considered as an efficient and effective tool for comprehensive study of reservoirs as well as reservoir management. In this study, which was carried out on one of the oil fields in the Persian Gulf, the aim is to simulate the petrophysical parameters of EFFECTIVE POROSITY and PERMEABILITY by using CO-SEQUENTIAL GAUSSIAN SIMULATION in part of Middle-Sarvak reservoir. With this simulation, a three-dimensional model of petrophysical reservoir parameters can be presented which is important for simulating fluid flow and identifying areas that are prone with higher reservoir quality. For this purpose, EFFECTIVE POROSITY and PERMEABILITY logs of seven wells with a 3D seismic cube and seismic inversion results have been used. After reservoir gridding and creating a structural model, up scaled petrophysical data has entered to a model. For three-dimensional distribution of EFFECTIVE POROSITY parameter, due to the correlation of EFFECTIVE POROSITY and acoustic impedance attribute of seismic inversion, up scaled EFFECTIVE POROSITY logs as the initial data and acoustic impedance attribute of seismic inversion as secondary data have entered using Sequential Gaussian Simulation and CO-KRIGING techniques. In order to simulate PERMEABILITY, due to the good relationship between the EFFECTIVE POROSITY model obtained by simulating and up scaled PERMEABILITY log, the EFFECTIVE POROSITY simulated as a secondary data and up scaled PERMEABILITY log is used as initial data in Sequential Gaussian Simulation and CO-KRIGING techniques. The results of VALIDATION indicate the accuracy of the present study and the efficiency of the Sequential Gaussian Simulation method in EFFECTIVE POROSITY and PERMEABILITY modeling in this reservoir.
