The well GDG-X has performed hydraulic fracturing stimulation at J 8 t o Fehruary 20, 2014 to increase production, but the result was not as expected so well dishutdown on 07 July 2014. From the observalion stages stimulation stimulation obtained Information that the implementation went smoothly without any obstacles resulting in fractures with a length of 118.1 meters, width of 0.12 inch and height of 12.90 meters fracture. After the analysis of the injection pressure (STP) is known turns injection pressure given the shortage of 893.113 psi of needs that amounted to 4491.113 psi. Shortage of clean injection pressure causes the pressure (P net) generated negative i n the amount of -763.023 psi. Clean pressure value under zero psi means signiftes that fractures will be closed again later. The results of the analysis of the required amount of fluid and proppant fracture the obtained amount of fluid needs fracturing fluids (V pad) and proppant mass (m propp) to form a fracture and prop that is shaped like the design size is as much as 8740.76 gal fracturing fluid and proppant Ibm 78666.84. When compared with the actual number is given then there is excess fracturing fluid much as 259.24 gal and proppant shortages as much as 46666.84 Ibm. Results of the analysis showed that the fractures that formed fractures formed State is not reached the size of the design or the desired target. It can be known from the analysis of the size of the fracture, fracture conductivity value (Fcd) and a multiple increase in productivity of the fracture (J / J o), llaving analyzed the size of the fracture or fractures formed geometry size turned out t o have a shortage of 1.87 m for the length of the wing fracture, shortage of 0.28 inch to 7.62 m in width and a shortage of high fracture. Fracture conductivity value (Fcd) formed turns out there is a shortage of 6.95 of a target of 10. multip/es of the increase in productivity (J / Jo) after the fracture is formed there is apparently a shortage of20.2 times to 31 times multiples of target after fracture formed later , From the analysis of reservoir production capability as seen from the inflow performance curve relationsip (IPR) was found to decrease the ability of the reservoir marked shift in the cttrve after stimulation of the left fence IPR IPR curve prior to stimulation with a maximum production rate (Omaks) after stimulation by 25.87 bfpd and prior to stimulation 61.15 bfpd which means a decline of35.28 bfpd.
