Abstract

A reservoir should have pores that can accommodate fluid. This capability is supported by the petrophysical properties which reservoirs have. The petrophysical properties depends on how the sediments were deposited. This study is focused on the deep marine turbidite outcrop. Turbidity currents are a sedimentation process which makes the sediments carried randomly at high velocity and low viscosity. The petrophysical properties such as porosity and permeability could be determined using computational fluid dynamics (CFD) analysis and routine core analysis. The approaches of this study are to analyze the petrophysical properties using CFD analysis and compare the results with the routine core analysis. The samples of this study were nine thin sections collected from the outcrops, especially in the middle and the edges of the turbidite channel. These samples then processed in the CFD software called COMSOL Multiphysics thus the porosity and permeability of these samples could be determined. The results show that the porosity values of the CFD analysis are relatively similar with the routine core analysis has and the permeability values of the CFD analysis are higher than the routine core analysis has.
