S Sumur X-1 adalah sumur gas condensate yang terletak di lapagan X, Pulau Sulawesi. Pada sumur X-1 telah dilakukan uji sumur dengan menggunakan pressure build up, dimana analisa dilakukan dengan tujuan untuk mendapatkan karakteristik reservoir dari sumur X-1 seperti permeabilitas, skin, flow efficiency dan radius of investigation. Pada pengujian pressure build up, dilakukan analisa dengan metode horner plot dan tekanan derivative plot dengan pendekatan pendekatan Ψ(P) pseudo pressure dan P2 dengan alasan sumur gas X-1 memiliki tekanan reservoir sebesar 2555 psia. Analisa dilakukan dengan menggunakan software saphir 3.20 dan Ms.Excel dimana hasil keduanya dibandingkan untuk melihat apakah ada kemungkinan kerusakan formasi. Analisa tipe model reservoir dan boundary effect untuk sumur X-1 juga diketahui yaitu homogenous with one fault boundary yang mengindikasikan terdapatnya patahan yang terletak pada jarak tertentu dari sumur X-1 yang mana patahan tersebut hanya membatasi satu arah dari reservoir. Diskritisasi pressure derivative dilakukan dengan metode two-points method dan three-points method, dimana hasil overlay kurva derivative nya match dengan deviasi hasil perhitungan kedua metode tersebut kurang dari 10%. Analisa horner plot juga dilakukan dengan pendekatan Ψ(P) pseudo pressure dan P2 yang mana dari hasil analisa horner plot mengunakan pendekatan Ψ(P) pseudo pressure pada saphir 3.20 diperoleh harga slope (m), permeabilitas, dan skin berturut-turut sebesar 322432 psi2/cp, 132 mD, dan 21.6, sedangkan hasil pada Ms.Excel diperoleh harga slope (m), permeabilitas, dan skin berturut-turut sebesar 320890 psi2/cp, 135 mD, dan 21.1. Untuk analisa horner plot mengunakan pendekatan P2 pada saphir 3.20 diperoleh harga slope (m), permeabilitas, dan skin berturut-turut sebesar 5495 psi2/cp, 125 mD, dan 21.3, kemudian untuk hasil pada Ms. Excel yakni diperoleh harga slope (m), permeabilitas, dan skin berturut-turut sebesar 5451.66 psi2/cp, 147 mD, dan 20.1. Hasil skin positif pada kedua metode menandakan bahwa sumur mengalami kerusakan (damage) dan memerlukan tindakan lanjut yakni stimulasi reservoir
W Wells X-1 is a gas condensate well which is located in filed X, Sulawesi Island. At well X-1 well test was conducted using pressure build up, where the analysis was conducted with objective to determine the reservoir characteristic of X-1 wells such as permeability, skin, flow efficiency and radius investigation. In the pressure build up test, the horner plot and pressure derivative analysis using pseudo pressure and P2 approaches were applied with the gas well X-1 has a reservoir pressure of 2555 psia. The analysis is done using saphir 3.20 and Ms.Excel software where the results to be compared to see if there is any possibility of formation damage. Well X-1 is also known as homogeneous with a fault boundary present located at a certain distance from the well, in which the fault is only one direction from the reservoir. The pressure derivative was conducted with two methods such as two-point method and three-point method, where the result of the overlay of the derivative curve corresponds to the deviation of the calculation result method which is less than 10%. The horner plot analysis is also done with the ψ(P) pseudo pressure and P2 approach which is the result of horner plot analysis using pseudo pressure ψ(P) pseudo pressure in saphir 3.20 obtained the slope (m), permeability, and skin values respectively were 322432 psi2/cp, 132 mD, and 21.6, whereas Ms.Excel results obtained the price of slope (m), permeability, and skin respectively were 320890 psi2/cp, 135 mD, and 21.1. To analyze the horner plot using the P2 approach at saphir 3.20 the value of slope (m), permeability, and skins values respectively were 5495 psi2/cp, 125 mD, and 21.3 and for the results of Ms. Excel the price of slope (m), permeability, and skin respectively were 5451 psi2/cp, 147 mD, and 20,1. Positive skin results in both methods of horner plot and derivative plot indicate the well is damaged and need to be stimulated.
