Abstract

Problems with sandstone reservoirs include the small initial permeability which will hinder fluid flow from the reservoir to the bottom of the well. This will cause a small initial productivity due to a small initial permeability so that it will be more difficult for oil to flow from the drain radius which causes a small Productivity Index value. The Hydraulic Fracturing stimulation method is applied to increase the permeability value by designing the fracture geometry, proppant size according to the fracture geometry, so that it is hoped that it can increase the permeability, transmissivity, production rate and productivity index. From the results of the research carried out, modeling results show that the success of hydraulic fracturing depends on the orientation of the fracture, the size and shape of the fracture, and rock properties such as permeability and strength. These results were proven by an increase in permeability which was previously only 2.3 mD after fracturing, increasing to 11.97 mD. The skin value which was previously 1.2 then improved to -6.31, which means the damage to the formation has been repaired. The productivity index, which was previously only 0.5 after fracturing, rose to 3.71. Lastly, the production rate also increased significantly from 28 Bopd neik to 129 Bopd. It can be said that the implementation of hydraulic fracturing in the AFG-01 Well was successful and effective in increasing production performance.
