INTRODUCTION

Core displacement test or coreflood is required to evaluate performance of injected chemicals or fluids at given pressure and temperature. The results from this test will be used to inform decisions regarding application of suitable process for near-wellbore production enhancement and improved oil recovery. The processes include matrix acidizing for carbonate and sandstone, water shutoff, sand consolidation and EOR processes such as surfactant and polymer flooding. In recent times, CO2 sequestration study also benefits from core displacement study to evaluate long term effect of CO2 injection into depleted reservoir. Early in the life of the reservoir, core displacement is used to characterize the reservoirs based on the measurement of rock properties such as porosity, permeability and relative permeability. 

This course explains the fundamentals of coreflood study by introducing the participants the equipment, theory and analysis that can be performed using coreflood. The advantage of having this knowledge will help users of coreflood study to gain better insight and make informed decisions affecting the reservoir performance.
