C02 flooding can be executed using several modes of injection teclmique such as continuous injection, simultaneous water and gas (SWAG) injection, water alternate gas (GAS) injection and hybrid WAG. Each of these injection modes will give certain amount of recovery based on their capability to restore formation pressure and also to improve oil displacement or fluid flow in the reservoir. Therefore, experiments or simulations may need to be conducted to determine the most effective injection mode which gives the most optimum recovery for a given reservoir. This project presents an experimental study of comparing different C02 injection mode for Baronia RV2 reservoir. It is the main objective to determine the most optimum C02 injection mode for this field. Using a coreflood equipment, C02 displacements were conducted on four core plugs saturated with Baronia RV2 crude oil. From the results of total oil recovered, it was found that SWAG is the most teclmically feasible mode for the field with over 60% recovery factor.
