Simulation of the effect of rock type on recovery plan of a mature carbonate oilfield in the Middle East – Part 1: Waterflooding recovery plan

Abstract

The X field is a mature carbonate oilfield in the Middle East, discovered in 1908. Several uncertainties exist in relative permeability data of the old X field, due to rock type diversity of the field. In this study, the effect of rock wettability on waterflooding process of this field is investigated by means of two reported wettability data sets of the field. Results show that initial rock wettability plays an important role in improving oil recovery, affecting production rate, recovery factor, breakthrough time, water cut, residual oil saturation, project life, etc.
