Analisis Uji Pressure Build Up Sebagai Dasar Optimasi Produksi pada Sumur AUD-1

Abstract

The AUD-1 well is an exploration well with a multilayer reservoir consisting of four reservoir layers, one oil reservoir and three gas reservoirs. The reservoir capability of the AUD-1 well can be analyzed through the Pressure Build Up test with well test interpretation. The results obtained based on the well test interpretation are reservoir characteristic parameters such as reservoir pressure, permeability and well skin. Well, reservoir and boundary models will also be known based on matching derivative curve models. The AUD-1 well, which has had its reservoir capacity evaluated, will undergo development planning so that optimal production can be carried out. The scope of development in question is determining the appropriate tubing diameter so that the production carried out can produce the most optimal flow rate. The selected tubing diameter range is between 2.5 inches – 7 inches taking into account the availability of the company's logistics stock. The results of the tubing sensitivity analysis show that tubing with a diameter of 2.5 inches will produce minimum production and tubing with a diameter of 7 will produce maximum production, but the optimum production rate of the AUD-1 well will greatly depend on the design of the forecast production rate by the development team.
