P ada analisis uji tekanan transient yang dilakukan pada sumur gas yaitu uji Pressure Build Up dan uji Deliverability dengan metode Modified Iscohronal. Dalam menganalisis ini dilakukan dengan dua cara yaitu menggunakan softwareEcrin dan juga Horner melalui metode pendekatan Pseudopressure ψ(P).Analisis Pressure Build Up bertujuan untuk mengetahui parameterparameter karakteristik reservoir diantara nya tekanan awal reservoir (Pi),permeabilitas (k), skin (s) dan juga dapat mengetahui model reservoir, modelsumur, serta model boundary. Sedangkan uji deliverability dilakukan untukmengetahui kemampuan suatu reservoir dapat mengalirkan fluida gas tersebut ataudisebut juga Absolute Open Flow Potential (AOFP).Hasil analisis yang diperoleh dengan menggunakan software Ecrin danHorner dengan metode pendekatan Pressure (P) dan Metode pendekatanPseudopressure ψ(P). Nilai yang diperoleh secara berturut-turut pada tekananawal reservoir sebesar 1.520,64 psia, dan 1.541 psia, nilai skin secara berturutturut sebesar 4,11, dan 3,656917847, nilai permeabilitas berturut-turut sebesar 992mD, dan 951,0984382 mD pada ketebalan formasi sedalam 9,8 ft. Sedangkan hasilanalisis uji deliverability yang dilakukan dengan menggunakan software Ecrin danMicrosoft Excel. Nilai AOFP yang diperoleh berturut-turut sebesar 108.730Mscf/d dan 113.503,0769 Mscf/d. Model yang diperoleh dari hasil analisisPressure Build Up ini dengan model Vertical Well Model, Constant WellboreStorage Model, Homogeneous Reservoir Model dan pada Boundary Model yaituRectangle.

I n the pressure transient analysis tests performed on gas wells with thePressure Build Up test and Deliverability test using the Modified Iscohronalmethod. In analyzing this is done in two ways, namely using Ecrin software andalso Horner method with the Pseudopressure ψ (P) approach.Pressure Build Up Analysis aims to determine the parameters of reservoircharacteristics between reservoir initial pressure (Pi), permeability (k), skin (s) andalso can find Well models, reservoir models and boundary models. While thedeliverability test is conducted to determine the ability of a reservoir to drain thegas fluid or also called Absolute Open Flow Potential (AOFP).The analysis results obtained using Ecrin and Horner software with thePressure (P) approach and the Pseudopressure ψ (P) approach. The valuesobtained respectively at reservoir initial pressure were 1.520,64 psia and 1.541psia, skin values were 4,11, and 3,656917847 respectively, permeability valueswere 992 mD, and 951,0984382 mD at formation thickness as deep as 9,8 ft. Whilethe results of the analysis of the deliverability test conducted using Ecrin andMicrosoft Excel software. AOFP values obtained were 108.730 Mscf/d and113.503,0769Mscf/d, respectively. The model obtained from the Pressure Build Upanalysis with the Vertical Well Model, the Constant Wellbore Storage Model, theHomogeneous Reservoir Model and the Boundary Model are Rectangle.
