Well “J” is a productive oil well that has average production of 276 BFPD and 95% water cut. The oil from this well is heavy since it has a specific gravity around 0.8649, 32.74 API, 107.6F of the pour point. As the production of the well progressed, a paraffin problem was discovered. The rod of the sucker rod pump was stuck at the perforated hole and it was predicted due to paraffin plugging. Research was done to solve this paraffin problem as well as to increase the production rate. The research shows that solvent injection on this well should be done. The solvent injection was concluded as a promising method to mitigate the problem because of its ability to dissolve the paraffin that has formed or collected near the formation face or on the tubular goods, and to lower the viscosity. As the result of the injection, this method shows that the production rate of this well increased up to 396 BFPD. Comparison of Viscosity, SG, API, and the production rate before and after solvent injection will be reviewed in this paper to elaborate the success of this project.
