Reservoir quality derived from routine core analysis data of deep-water turbidite outcrop analogue

Abstract

Turbidity current is a process where the fluid flows occurs as a turbulent flow where the molecules inside the fluid are moving randomly but with a net movement toward the orientation of the transport. The physical properties of turbidite deposit is highly impacted by the grain size distribution and rock texture during the deposition. The field in this study was an outcrop of Jatiluhur Formation which deposited by turbidity current on deep marine environment. The main goal of this study was to understand the correlation between the petro-physical properties of turbidite deposit with its depositional mechanism using the routine core analysis method. The samples in this study were collected from an outcrop and the routine core analysis data contains the percentage value of porosity and vertical permeability. The result of this study were the porosity was relatively equal to the permeability and depositional mechanism had a significant role in controlling the porosity and the permeability.
