"Daerah penelitian AM merupakan salah satu daerah prospek geotermal yang berlokasi di Kabupaten OKU Selatan, Provinsi Sumatera Selatan. Potensi geotermal pada daerah penelitian ditandai dengan kemunculan manifestasi berupa lima mata air panas bersuhu 44,4o – 92,5oC dan pH antara 8,19 – 9,43. Penelitian ini bertujuan untuk mengidentifikasi struktur geologi bawah permukaan melalui gravitasi satelit GGMplus serta data pendukung geologi dan geokimia. Struktur pada peta geologi didominasi oleh sesar regional berarah barat laut-tenggara. Hasil analisis slicing lintasan First Horizontal Derivative (FHD) dan Second Vertical Derivative (SVD) menunjukkan adanya enam patahan pada area penelitian dan dikonfirmasi dengan data geologi. Perkiraan temperatur reservoir daerah penelitian AM berdasarkan geotermometer geokimia Na-K berkisar antara 146o - 176oC.......The research area AM is one of the geothermal prospect area located in South OKU Districts, South Sumatera. The existence of the geothermal system in the research area is indicated by the presence of five hot springs with a temperature of 44.4 – 92.5°C and a pH between 8.19 – 9.43. This study aims to be able to identify the subsurface geological structures through GGMplus satellite gravity, as well as geological and geochemical supporting data. The structures on the geological map are dominated by northwest – southeast regional fault. The results of the First Horizontal Derivative (FHD) and Second Vertical Derivative (SVD) slicing analysis indicate six faults in the research area and confirmed with geological data. The reservoir temperature in the research area AM is estimated around 146o – 176°C based on Na-K geothermometer."

"Lapangan TA adalah salah satu lapangan yang beroperasi di bawah PT. Chevron Pacific Indonesia yang telah ditindaklanjuti dengan teknologi baru dalam upaya peningkatan produksi. Berdasarkan data log, Formasi Menggala merupakan perselingan batupasir dan batulempung. Dari penampang seismik diinterpretasikan bahwa terdapat struktur geologi berupa sesar mendatar dan sesar naik. Data Log dan Seismik 3D dapat diolah untuk mendapatkan model bawah permukaan yang lebih baik. Tahapan pengolahan data dimulai dengan korelasi sumur, lalu dilakukan well-seismic tie untuk meletakkan horizon seismik (skala waktu) pada posisi kedalaman sebenarnya yang akan digunakan pada proses picking horizon. Setelah itu dilakukan analisa seismik atribut amplitudo rms, amplitudo palung maksimum, dan atribut kuat refleksi. Dari hasil pengolahan data, diduga terdapat tiga area potensi pengembangan (lead) pada Lapangan TA. Dari ketiganya, lead 1 diduga sebagai daerah yang paling berpotensi berdasarkan peta struktur waktu terdapat closure, peta ketebalan formasi, dan peta atribut dimana zona interest berada di antara 10-20 ms. Pada daerah ini batuan induknya merupakan Kelompok Pematang yaitu Formasi Brown Shale dan tipe kerogen 1 atau 2, reservoar berada pada Formasi Menggala, jebakan berupa struktur lipatan, migrasi primer, dengan batuan tudung Formasi Bangko.

TA field is one of PT. Chevron Pacific Indonesia?s operating areas that has been obtained new technologies due to increase production. Based on Log Data, Menggala Formation was formed by combination of sandstone and shale. Interpretation from seismic section, there is a geological structures such as normal fault and reverse. Well Log Data and 3D Seismic Data can be processed to get more accurate subsurface model. Stage of processing data started with log correlation and then well-seismic tie for interpreted seismic horizon on time domain that will be used for picking horizon. After that running rms amplitude seismic attribute, maximum trough attribute, and reflection strength attribute. From the results of data processing, supposedly there are three potential areas of development in the TA field. Of the three, lead one suspected as the most potential area (lead) are based on the structure of time there is closure, formation thickness maps, and attributes maps in which the interest zone between 10-20 ms. In this area, the source rock is a group of Pematang is Brown Shale Formation and type of kerogen is 1 or 2, reservoir on this field is Menggala Formation, trapped in a fold structure, primary migration, with Bangko Formation as the seal."
