Hydraulic Fracturing Planning to Increase Well Productivity in RAG Well of Cessna Field
The RAG well is an oil well that has been workover by moving layer workover at a depth of 3788.1 - 3820.1 ft MD in TAF tight sandstone formation with a directional well configuration located in the Cessna field of the Northern West Java basin. This well has a shaly sandstone reservoir with silt rock intrusions with a permeability value of 10 mD and a porosity of 15%. This low permeability of the formation may affect the daily barrel fluid per day produced from the well, this is the main reason why it is necessary to plan stimulation in the form of hydraulic fracturing in RAG well with the hope of increasing well productivity in RAG well. The method used in planning the implementation of hydraulic fracturing in RAG well includes planning hydraulic fracturing on RAG well, followed by executing hydraulic fracturing based on the simulation design, as well as analyzing the success of hydraulic fracturing in accordance with the planning that has been carried out. Based on the results of the analysis of hydraulic fracturing success parameters, it was found that there was an increases in production parameter post hydraulic fracturing job in the RAG well, including an increases in the average permeability of the formation from 10 mD to 162.89 mD, fold of increase (FOI) to 6.33, productivity index, oil flow rate based on Wiggins IPR analysis from 6.39 Bopd to 40.44 Bopd with the maximum fluid flow rate also increasing from 86.97 Bfpd to 550.67 Bfpd.
