Stimulation-Based Recovery Enhancement Feedback of Oil-Rim Reservoirs
Oil-rim reservoirs are considered as some of the unconventional reservoirs in which a thin oil layer, a thick gas cap and an aquifer layer are involved. The economic prosperity of drilling this type of reservoirs, involves novel enhanced oil recovery techniques to produce more oil volume. Production from oil-rim reservoirs would be a particular challenge due to their unique characterization. In this comprehensive study, we simulate six different scenarios with drilling new wells horizontally or vertically on the oil recovery enhancement for selecting 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 key parameters of gas/oil ratio, water cut and, pressure drop. The drilling of a horizontal well (and its potential contact with the reservoir) results in the best performance among other scenarios, and scenarios of drilling new vertical wells have yielded excellent results for commencing the production operation.
