Z Zona aliran yang berbeda akan terbentuk di dalam reservoir pada saat fluidagas mengalir dengan tekanan dasar sumur di atas tekanan dew point. Zona aliranini dapat diinterpretasikan salah satunya dengan analisis uji pressure build-updengan menggunakan metode horner dan type curve derivative. Analisis ini dapatdilakukan dengan baik pada reservoir dengan sistem homogen karena sifatnyayang sederhana. Penelitian ini dilakukan untuk mencari informasi parameter dankarakteristik reservoir yang memiliki kandungan fluida gas di dalamnya.Parameter reservoir yang bisa didapatkan yaitu seperti tekanan reservoir awal( ), permeabilitas (k), faktor skin (s), Flow Efficiency (FE), batas reservoir(boundary), besar daerah pengurasan sumur, tekanan rata-rata reservoir ( ) danAOFP. Sumur eksplorasi FT-1 menembus formasi sandstone dengan kandunganhidrokarbon gas. Analisis uji sumur yang dilakukan adalah analisis tekanandengan pengujian pressure build-up dan analisis deliverabilitas dengan pengujianmodified isochronal (MIT). Pada analisis dengan menggunakan type curvederivative plot digunakan metode three points-method dimana hasil overlay kurvaderivative match dengan deviasi hasil perhitungan. Analisa horner plot jugadilakukan dengan menggunakan pendekatan pseudo pressure (m(P)) danpendekatan squared pressure (P2). Hasil analisis yang diperoleh menunjukanreservoir dengan model homogeneous serta model boundary intersecting faults,dengan perolehan nilai permeabilitas sebesar 14,6 md, skin -0.85, tekanan awal562,83 psia, tekanan rata-rata reservoir dengan menggunakan metode Rameycobbsebesar 533,40 psia, MBH 414,33 psia, MDH 509,6 psia, modified Muskat550 psia, dan Arp-smith 521,67 psia dan AOFP sebesar 1026.24 MSCF/D.

D Different flow zones will form in the reservoir when the gas fluid flowswith the well bottom pressure above the dew point pressure. This flow zone can beinterpreted one of them by analyzing the pressure build-up test using the hornermethod and curve curve type. This analysis can be done well on reservoirs with ahomogeneous system because of their simple nature. This research was conductedto find information on reservoir parameters and characteristics that have a gasfluid content in it. Reservoir parameters can be obtained, such as initial reservoirpressure (pi), permeability (k), skin factor (s), Flow Efficiency (FE), reservoirboundary (boundary), large drainage area, average reservoir pressure (pr) andAOFP. FT-1 exploration well penetrated sandstone formation with gashydrocarbon content. The well test analysis conducted is pressure analysis withpressure build-up testing and deliverability analysis with modified isochronal(MIT) testing. In the analysis using the type curve derivative plot the three pointmethodis used where the results of the overlay of the derivative curve match thedeviation of the calculated results. Horner plot analysis is also performed usingthe pseudo pressure (m (P)) approach and the squared pressure (P2) approach.The analysis results obtained show a reservoir with a homogeneous model and aboundary intersecting faults model, with the acquisition of permeability values of14.6 md, skin -0.85, initial pressure of 562.83 psia, average reservoir pressureusing the Ramey-cobb method of 533.40 psia,MBH method with 414.33 psia,MDH method 509.6 psia, modified Muskat method with 550 psia, and with Arpsmithmethod 521.67 psia and AOFP of 1026.24 MSCF / D.
