%X Daerah penelitian terletak pada Cekungan Sumatera Selatan, tepatnya pada Formasi  Air Benakat yang berada di bagian tenggara Provinsi Jambi. Penelitian ini  dilakukan untuk mengetahui dimana zona-zona produktif berdasarkan analisis  parameter petrofisika (saturasi air, porositas dan vshale), serta bagaimana  karakteristiknya. Interpretasi pintas menghasilkan zona-zona permeable dan zona  produktif di setiap sumur. Adapun litologi pada sumur TRD adalah batupasir  (sandstone) dengan sedikit kandungan foraminifera di dalamnya. Penentuan ini  didasarkan pada hasil analisis petrofisika dengan hasil rata-rata porositas zona 7  pada sumur TRD-10 sebesar 12,4%, Sw 19,4% dan Vsh 6,2%; zona 7 sumur TRD-  11 porositas 16,2%, Sw 41,3%, dan Vsh 22%; zona 11 pada sumur TRD-14  porositas 33,2%, Sw 21,2% dan Vsh 1,2%; zona 6 sumur TRD-15, porositas 7,02%,  Sw 32,3% dan Vsh 5,6%; zona 7 sumur TRD-17, porositas 9,04%, Sw 25,6% dan  Vsh 4,6%; dan zona 4 sumur TRD-19, porositas 23,2% Sw 13,5% dan Vsh 7,1%.  Hasil ini juga dapat dilihat pada penampang net pay 2D dan 3D yang merupakan  persebaran parameter petrofisika. Karakteristik reservoar pada sumur TRD ini  relatif memiliki saturasi yang rendah di bawah 50%, porositas lebih dari 5 % dan  kandungan lempung kurang dari 25%, sehingga dapat dikatakan zona produktif  pada sumur TRD berpotensi gas.

The research conducted to know productive the  interest zone by petrophysics analysis (volume shale water saturation, and porosity)  and its characteristics by well-log. By the quicklook interpretation got permeable  zones and productive zones each well. The lithology of TRD Well is sandstone with  a few foraminifera. The interpretation based on the petrophysical analysis porosity  of the 7th zone on TRD-10 is average 12,4%, saturation water 19,4% and volume  shale 6,2%; the 7th zone on TRD-11 well is average porosity 16,2%, saturation  water 41,3%, and volume shale 22%; the 11th zone on TRD-14 well is average  porosity 33,2%, saturation water 21,2% and volume shale 1,2%; The 6th zone TRD-  15 well, porosity 7,02%, saturation water 32,3% and volume shale 5,6%; On the  TRD-17 well of the 7th zone is average the porosity 9,04%, saturation water 25,6%  and volume shale 4,6%; and 4th zone of TRD-19 well, porosity 23,2% Saturation  water 13,5% and volume shale 7,1%. Based on the result showed by netpay 2D and  3D Crosssection which are the distribution of petrophysical parameters. The  characteristics of hydrocarbon reservoir on TRD Wells have low water saturation  is less than 50%, porosity more than 5% and volume shale less than 25%. From the  result of petrophysics parameter value used as the indicator of the productive zone  and interpreted that sand reservoir on well TRD has potentially for the reservoir  zone with gas prospect.  Keywords: petrophysics, saturation water, porosity, volume shale and netpay.
