A declining performance an oil well production can be influenced by several factors, such as the reservoir's decreased ability to flow fluids into the oil well due to low permeability in the perforated zone and high skin in the formation. To solve this problem, an effective method is needed to increase permeability and reduce skin to enhance productivity. This study focuses on the hydraulic fracturing design for well SR-16 with proppant mass sensitivity. The objective is to bypass the near wellbore low permeability and damage zone to make connectivity between the wellbore and the porous zone. The study used P3D fracture geometry model to develop simultaneous lateral and vertical fracture migration. Based on mass proppant sensitivity by optimum CFD value, the braddy 20/40 proppant type with an optimum mass of 47 klb was selected to achieve an optimum CFD value of 1.6. The fracture design results obtained half-fracture length of 131.8 feet and a fracture width of 0.197 inch. The effective conductivity value with a 47 klb proppant mass is 1076 mD.ft, and the skin value after fracturing is -5.27391. The fold of increase in productivity after hydraulic fracturing is 2.721317. The value of fold of increase show that this method is effective in enhancing well productivity 2.721317 times than before.
