S Setelah proses pemboran suatu sumur selesai dilakukan, maka dilakukansuatu pengujian sumur hidrokarbon yaitu uji sumur (well testing). Salah satu tujuandari uji sumur yaitu untuk menganalisis parameter – parameter reservoir sepertitekanan awal reservoir, permeabilitas, kerusakan formasi, batas reservoir, sertakemampuan produksi dari suatu lapisan atau formasi. Sumur AZ-01 merupakansumur baru yang dilakukan pengeboran pada tahun 2016. Sumur AZ-01 terletakpada lapangan AZF di Kabupaten Subang Provinsi Jawa Barat yang , dimana jenisreservoir nya adalah condensate gas reservoir dengan jenis batuan karbonat.Analisis tekanan yang dilakukan pada Sumur AZ-01 yaitu uji PressureBuild Up dan deliverability. Kedua uji tekanan tersebut dilakukan denganmenggunakan software Ecrin dan secara manual dengan Microsoft Excel. Hasilanalisis uji Pressure Build Up pada Sumur AZ-01 dengan Type Curve PressureDerivative, model sumur yang didapat adalah Vertical dengan model reservoiradalah Two Porosity PSS dan model boundary adalah parallel fault, dimana tekananreservoir yang didapat adalah 2546 psia dengan skin yang negatif yaitu -4.54 sertanilai permeabilitas sebesar 0.315 mD. Sedangkan nilai Absolut Open FlowPotential (AOFP) pada Sumur AZ-01 berdasarkan analisis uji deliverabilitas adalahsebesar 652.90 mscf/D dengan nilai n sebesar 0.8.

A After the drilling of a well is completed, a hydrocarbon well test is carriedout, namely well testing. One of the objectives of the well test is to analyze reservoirparameters such as initial reservoir pressure, permeability, formation damage,reservoir boundary, and production capability of a layer or formation. AZ-01 wellis a new well that was carried out drilling in 2016. The AZ-01 well is located in theAZF field in Subang Regency, West Java Province which has a reservoir layer,where reservoir type is a condensate gas reservoir with rock types carbonate.Pressure analysis carried out on AZ-01 Well is Pressure Build Up anddeliverability test. Both pressure tests were carried out using Ecrin software andmanually with Microsoft Excel. The analysis of the Pressure Build Up test on theAZ-01 Well with the Type Curve Pressure Derivative, the well model obtained isVertical with the reservoir model is Two Porosity PSS and the boundary model isa parallel fault, where the reservoir pressure obtained is 2546 psia with a negativeskin that is -4.54 and the permeability value is 0.315 mD. Whereas the AbsoluteOpen Flow Potential (AOFP) value on AZ-01 Well based on the deliverability testanalysis is 652.90 mscf / D with a n value of 0.8.
