D Deliverabilitas untuk sumur gas adalah kemampuan daripada reservoir untuk memproduksikan gas tersebut. Karena adanya perbedaan tekanan, gas yangterdapat di dalam reservoir dapat mengalir kepermukaan melalui pipa produksidalam sumur. Dari ketiga metode test ujisumur yaitu flow after flow, isochronal test, dan modified isochronal test. Yang digunakan dalam Tugas Akhir ini adalah flow after flow. Dalam penentuan Absolute Open Flow Potential (AOFP), ada dua metode yang digunakan yaitu metode Rawlins &Schellhardt secara konvensional dan metode Houpeurt (European Method) dengan analisa pseudopressure. Dari hasil perhitungan deliverabilitas gas pada lapangan Z sumur ZR-03 dengan metode Houpeurt (European Method) dengan pseudopressure diperoleh AOFP (Absolut Open Flow Potensial) sebesar 451.3 MMscfd. Dengan koefisien A sebesar -0.0029 psia²/cp/MMscfd dan koefisien B sebesar 0.004465 psia²/cp/MMscfd. Sedangkan metode kedua yaitu Rawlins &Schellhardt secara konvensional diperoleh nilai AOFP sebesar 432.4 MMscfd dengan nilai n sebesar 0.70 dan C sebesar 0.0035.

D Deliverability of a gas well is the ability of a reservoir to producing its gas.Because there is difference on pressure, gas which contain in the reservoir canflow to the surface through production pipe inside the well. From 3 methods of well testing, that are back pressure test (flow after flow), isochronal test, and modified isochronal test, the one which chosen in this Final Assignment is back pressure test (flow after flow). To determine Absolute Open Flow Pontential (AOFP), there are two methods that can be used, that are conventional Rawlins &Schellhardt method and Houpeurt method (European Method) with pseudopressure analysis. Based on the result of gas deliverability at Z field ZR-03 well using Houpeurt method (European Method) with pseudopressureanalysis the value of AOFP (Absolute Open Flow Potensial) is 451.3 MMscfd, which the value of A coefficient is -0.0029 psia2/cp/MMscfd and B coefficient 0.004465 psia2cp/MMscfd. On the other hand, the second method which is conventional Rawlins &Schellhardt method give the number of AOFP is 432.4 MMscfd with the n input 0.70 and C 0.0035.
