A Analisa uji Pressure Build Up (PBU) dan uji deliverabilitas dilakukan pada data Drill Stem Test (DST) dari sumur T-5. Reservoir sumur T-5 adalah dry gas dengan jenis batuan sandstone. DST dilakukan pada kedalaman 12,366 ft.Analisa PBU akan menghasilkan parameter reservoir penting berupa permeabilitas, faktor kerusakan formasi (skin), dan estimasi tekanan rata-ratareservoir. Analisa uji deliverabilitas dilakukan dengan tujuan untuk memperolehestimasi produktivitas sumur atau Absolute Open Flow (AOF). Analisa PBU dilakukan menggunakan metode grafik semilog (Horner plot) dan grafik log-log (type curve matching). Analisa uji deliverabilitas dilakukan dengan metode LIT; metode analisa konvensional juga digunakan sebagai pembanding. Analisa PBU dan deliverabilitas dilakukan dalam parameter pseudo pressure untuk mengingkatkan ketelitian hasil perhitungan. Hasil analisa semilog menunjukan nilai permeabilitas sebesar 196.9 mD dan skin sebesar 43.6. Berdasarkan analisa log-log PBU, diketahui model reservoir adalah homogenous dengan kondisi batas reservoir infinite boundary. Dari analisa log-log, nilai permeabilitas yang didapatkan adalah 196 mD dan skin sebesar 43.3. Kemiripan hasil analisa log-log dan semilog mendukung kecocokan model yang digunakan. Analisa uji deliverabilitas dengan metode LIT menghasilkan nilai AOF sebesar 217.73 MMscfd sedangkan analisa konvensional menghasilkan nilai AOF sebesar 223.63 MMscfd.

P Pressure Build Up and Deliverability test analysis were performed on the Drill Stem Test (DST) Data of Well T-5. Well T-5 reservoir is a dry gas reservoir with sandstone rock formation. The DST was performed at the depth of 12,366ft.PBU analysis will result some of important reservoir parameters such as permeability, formation damage factor (skin), and arbitrary average reservoirpressure. Deliverability analysis is performed with the aim to obtain theestimation of productivity potential of a well or Absolute Open Flow (AOF).PBU analysis was performed using graphical method of semi log plot (Horner plot) and log-log plot (type curve matching). The deliverability analysis was performed using LIT method; also, the conventional deliverability analysismethod is used as a comparison. Both PBU and deliverability analysis wasperformed using the pseudo pressure parameter to for accuracy enhancementtoward the result parameters. Semi log analysis results an permeability value of 196.9 mD and skin value of 43.6. Based on log-log plot analysis of PBU, the reservoir model is interpreted as homogenous and infinite boundary type reservoir. From log-log analysis, permeability result is at the value of 196 mD and skin factor is 43.3. Those matching values between log-log and semi log analysis confirm that the interpreted model is right. Deliverability analysis using LIT method results 217.73 MMscfd AOF, where as conventional method analysis yields 223.63 MMscfd AOF.
