Abstract

“X” well is a well with a productive sandstone formation with a productivity index of 0.1 bfpd/psi. Hydraulic fracturing will be performed based on screening results, with design simulated using commercial software. The design process includes analyzing well data, reservoir characteristics, and rock geomechanics using the Perkins, Kern, and Nordgren (PKN) fracture model. The chosen fracturing fluid is YF135.1HTD with Carbolite Proppant (12/18 mesh). The geometric model applied uses the PKN method with results of a fracture length of 463.9 ft, fracture height of 9.84 ft, fracture width of 0.37 inch, and fracture conductivity of 77063 md.ft using a total volume of fracturing fluid of 13500 gallons and a total mass of proppant. amounting to 40590 lbs. The required surface injection pressure is 4176.13 psi with an injection rate of 18 bpm and a total pumping time of 20.2 minutes. The performance improvement of the “X” well was in the form of average formation permeability from 29.2 mD to 369.4 mD, an increase in productivity index of 6.5 times and an increase in production rate from 50.46 bfpd to 296.48 bfpd. So, the planning of the hydraulic fracturing design for the “X” Well can be considered for implementation.

Abstract

Solution Gas Drive-Naturally Fractured Reservoir (NFR) has relatively high remaining oil reserves. This causes less optimum oil from the reservoir to be produced to the surface, so that it requires an enhanced oil recovery (EOR). EOR can be done by chemical injection, one of which is by polymer injection. Polymer injection emphasizes improving the swept efficiency. The most important parameter in this case is the mobility ratio. The injection process is very dependent on reservoir fluid characteristics, rock heterogeneity, and interactions between fluid and rock. Therefore, studies are needed to understand the mechanism of polymer injection that occurs in the reservoir.Simulation modelling of polymer injection on solution gas drive naturally fractured carbonate reservoir will be done using a black-oil simulator. In the black oil simulator it can be observed changes in the parameters of the mobility ratio of water to oil. In this simulation will run water flooding case as comparison to polymer injection case.The purpose of this study is to observe an increase in recovery factor with water flooding and polymer injection scenario on solution gas drive-NFR. The scenario that provides the greatest recovery factor can be considered in carrying out a strategy to increase oil recovery at EOR methods.
