Abstract

P Pada Tugas Akhir ini membahas Uji Pressure Build Up dan Uji Deliveravilitas suatu sumur. Pada sumur AMP-01 ini telah dilakukan proses Stimulasi, selanjutnya dilakukan pengujian sumur yaitu well testing. Tujuan dilakukannya well testing pada sumur AMP-01 adalah untuk membuktikan keberhasilan stimulasi yang dilakukan pada sumur ini dengan menentukan parameter-parameter reservoir seperti tekanan reservoir, permebilitas (k), factor skin, dan penurunan tekanan akibat skin (Î”Pskin). Tujuan dilakukannya Uji Deliverabilitas adalah untuk mengetahui kemampuan produksi dari suatu sumur gas.Analisis tekanan yang dilakukan pada sumur AMP-01 yaitu Uji pressure build up dengan metode horner plot dengan pendekatan Pseudo Pressure Î¨(P). Analisis Horner yang dilakukan menggunakan software dan perhitungan manual dengan Spreadsheet menunjukan hasil yang hampir sama, dimana dalam perhitungan manual didapatkan nilai tekanan reservoir yang sebesar 835.556 psi, nilai permebilitas sebesar 28.21 mD, nilai skin sebesar -4.28, dan penurunan tekanan akibat skin (Î”Pskin) sebesar -45.47 psi dengan Flow Effeciency sebesar 2.28, dan radius investigasi sebesar 788.13 ft. selanjutnya dilakukan uji deliverabilitas pada sumur AMP-01 dengan menggunakan metode Modified Isochronal Test. Plot yang dilakukan yaitu dengan memplot laju alir gas vs penurunan tekanan, nilai AOFP (Absolute Open Flow Potential) pada sumur ini berdasarkan analisis uji deliverabilitas yaitu sebesar 4147.85 MSCF/D dengan nilai back pressure coefficient (C) sebesar 6.179 dan nilai slope (m) 0.5.Hasil analisis dengan bantuan software menghasilkan permeabilitas 24.6 mD, skin -4.54, dan penurunan tekanan akibat skin (Î”Pskin) sebesar -54.7821 psia. Selain itu jenis sumur yang didapat adalah Vertical, Changing Storage (hegeman) dengan jenis reservoir Two Porosity Spahere dan jenis Boundary-nya Rectangle.Selanjutnya dilakukan perhitungan tekanan rata-rata (Pavg) pada sumur AMP-01. Perhitungan tekanan rata-rata (Pavg) ini dilakukan pada saat Middle Time Region (MTR) dan Late Time Region (LTR). Tekanan rata-rata (Pavg) pada saat Middle Time Region dilakukan dengan 2 metode yaitu metode Matthew Brom Hazebrook (MBH) dan metode Dietz. Sedangan pada saat Late Time Region (LTR) dilakukan dengan 2 metode yaitu metode Arps Smith dan metode Modified Muskat. Perhitungan tekanan rata-rata (Pavg) pada saat Middle Time Region dengan metode MBH didapatkan sebesar 803.24 psi dan dengan menggunakan metode Dietz didapatkan sebesar 831.9 psi. Tekanan rata-rata (Pavg) pada saat Late Time Region dengan metode Arps Smith didapatkan sebesar 827 psi dan dengan metode Modified Muskat didapatkan sebesar 845 psi.

I In this Final Project discuss Pressure Build Up Test and Deliveravability Test of a well. In the AMP-01 well, the Stimulation process has been carried out, then the well is tested, well testing. The purpose of doing well testing at AMP-01 well is to prove the success of the stimulation carried out in this well by determining reservoir parameters such as reservoir pressure, permeability (k), skin factor, and pressure drop due to skin (kinPskin). The purpose of the Deliverability Test is to determine the production capability of a gas well.Pressure analysis carried out on AMP-01 wells is a pressure build up test with the horner plot method. Horner's analysis using software and manual calculations with Spreadsheets shows almost the same results, where in the manual calculation the reservoir pressure value is 835,556 psi, the permeability value is28.21 mD, the skin value is -4.28, and the pressure drop due to skin (Î”Pskin ) amounting to -45.47 psi with a Flow Efficiency of 2.28, and an investigation radius of 788.13 ft. then the deliverability test is carried out on the AMP-01 well using the Modified Isochronal Test method. The plot is done by plotting the gas flow rate vs. pressure drop, the AOFP (Absolute Open Flow Potential) value in this well based on the deliverability test analysis that is equal to 4147.85 MSCF/D with the back pressure coefficient (C) of 6.179 and the slope (m) 0.5.The results of the analysis with the help of software produced permeability of 24.6 mD, skin -4.54, and a decrease in pressure due to skin (Î”Pskin) of -54.7821 psia. Besides that the type of well obtained is Vertical, Changing storage (hegeman) with the type of reservoir Two Porosity Spahere and the boundary type Rectangle. Then the calculation of the average pressure (Pavg) in the AMP-01 well.This average pressure calculation (Pavg) is carried out in the Middle Time Region (MTR) and Late Time Region (LTR). The average pressure (Pavg) during the Middle Time Region is done by 2 methods, namely the Matthew Brom Hazebrook (MBH) method and the Dietz method. During the Late Time Region (LTR) it was conducted with 2 methods, namely the Arps Smith method and the Modified Muscle method. Calculation of the average pressure (Pavg) in theMiddle Time Region with the MBH method was obtained at 803.24 psi and using the Dietz method obtained at 831.9 psi. The average pressure (Pavg) during the Late Time Region with the Arps Smith method was obtained at 827 psi and with the Modified Muskat method obtained at 845 psi.
