average inclination. Drilling target is the reservoir F22, which has been depleted with reservoir pressure lies in 700 psi. Simulation on Inflow Performance Relationship and Tubing Performance Relationship shows that the well cannot produce in natural way. Hence, the need for artificial lifting (in this case is gas lift) become apparent. Gas Lift Performance Curve study with water cut sensitivity is conducted to determine optimum gas injection rate. The result obtained is the range of optimum gas injection rate, which value lies from 0.5 mmscfd to 0.96 mmscfd. The high degree of inclination prevents future Gas Lift Valve Redesign operation to be executed, making any gas lift configuration designed should be permanently operational until abandonment. Design configuration includes kickoff pressure point and flowing pressure gradient, set respectively at 690 psia and 0.11 psi/ft. Three Gas Lift Mandrels will be set each in three injection point obtained. Pressure Test Rack Opening process suggests the use of two 0.1875 inch unloaders and one 0.3125 inch orifice, each to be set for each of the three Gas Lift Mandrels. |
