Analisa pressure build up pada sumur R dengan menggunakan software X
U Uji sumur adalah kegiatan untuk mengetahui kemampuan suatu sumurmemproduksikan hidrokarbon. Salah satu metode untuk mengetahui parameterserta karakteristik suatu reservoir adalah dengan analisis tekanan transien dengancara Pressure Build Up analisis. Parameter yang dihasilkan dalam uji sumur iniadalah, model reservoir, batas reservoir, tekanan awal reservoir, kerusakanformasi, permeabilitas, radius investigasi, serta laju alir maksimal gas berdasarkankurva Inflow Performance Relationship. Hasil yang didapat dari analisa uji sumurpada sumur R menggunakan software X dan perhitungan manual denganMs.Excel menunjukkan bahwa wellbore model pada sumur R yaitu ChangingWellbore Storage, dan jenis reservoir Homogeneous, serta batasan reservoirRectangle. Karakteristik formasi berdasarkan analisa software X pada sumur Radalah nilai pressure initial sebesar 3271,43 psia, permeabilitas sebesar 6,26 mD,total skin sebesar -1,6. Sedangkan untuk pengerjaan secara manual menggunakanmicrosoft excel yaitu pressure initial (Pi) sebesar 3220,7108 psia, permeabilitassebesar 6.16 mD, total skin sebesar -1,618. luas radius pengurasan sebesar533352,12 ft2, dan nilai laju alir maksimal dengan berdasarkan kurva IPR sebesar4364,025264 Mcfd. Hasil skin yang negatif menunjukkan bahwa stimulasi yangtelah dilakukan sebelumnya telah berhasil.
W Well testing is an activity to determine the ability of a well to producehydrocarbons. One method to determine the parameters and characteristics of areservoir is by transient pressure analysis by means of Pressure Build Upanalysis. The parameters produced in this well test are reservoir model, reservoirlimit, initial reservoir pressure, permeability, formation damage, investigationradius, and maximum gas flow rate based on the Inflow Performance Relationshipcurve. The results obtained from the analysis of the well test in well R usingsoftware X and manual calculations with Ms.Excel show that the wellbore modelin well R is Changing Wellbore Storage, and the reservoir type is Homogeneous,as well as Rectangle reservoir boundaries. The characteristics of the formationbased on the analysis of software X in well R are the initial pressure value of3271.43 psia, permeability of 6.26 mD, total skin of -1.6. Meanwhile, for manualprocessing using Microsoft Excel, the initial pressure (Pi) is 3220.7108 psia,permeability is 6.16 mD, total skin is -1.618. The drainage radius is 533352.12ft2, and the maximum flow rate based on the IPR curve is 4364.025264 Mcfd. Anegative skin result indicates that the previous stimulation has been successful..
