Abstract

Oil-rim reservoirs are a kind of such unconventional reservoirs which the oil layer was occupied by the gas cap and aquifer layer. Regarding the economic prosperity of drilling this reservoir types, petroleum engineers would always try to find novelistic enhanced oil recovery techniques to produce more oil volume which economically profitable owing to the vast experiences of drilling and production operations are. However, oil-rim reservoirs production would be a particular challenge due to its unique characterization for several decades, in this comprehensive study, we try to simulate six different scenarios with drilling new wells horizontally or vertically on the oil recovery enhancement and choose the optimum technique which has more compatibility with the reservoir characteristics. Moreover, another objective of this study is to investigate the dominant influence of simulation procedures in each scenario on the critical parameters of gas oil ratio, water cut and, pressure drop. Consequently, scenario six regarding the drilling of a horizontal well and its potential contact with the reservoir has been the best scenario among other scenarios and scenario four and five due to the drilling new vertical wells have witnessed an excellent economical choice for commencing the production operation.
