| Summary: | The injection of water into the reservoir (water-flood) is the most commonly used method of displacing the oil left in rock formations. However, a large quantity of oil still left in reservoir known as residual oil saturation due to capillary effect and viscosity ratio, gravity effect, in microscopic pore spaces and the other complex factors of recovery mechanisms. One factor which significantly affects the recovery factor of a water-flood process is the injection-production well pattern. Theoretically, the areal efficiency on a 2D model is more affected by the mobility ratio between the displacing fluid and displaced fluid and also the well pattern. <br />

This paper discuss about the effect of water injection on the oil recovery factor in a 1/8 9-spot 2D physical model which has a dimension of 15 cm x 15 cm x 0.157 cm. This 2D physical model was made of 35-40 mesh quartz sands used as artificial oil reservoir. The approaching method of this 2D model is more reliable and acceptable as a reservoir representative than one dimension displacement in core plug. In order to recover oil from 2D reservoir physical model, amount of water injected to simulate both primary and secondary oil recovery in laboratory. The due recovery factor for this water-flood method was about 70% of OOIP. |
