D Daerah penelitian dilakukan pada lapangan RMA yang terletak di Cekungan Sumatera Selatan, Sumatera Selatan dan berada pada Formasi Talang Akar. Dalam Penelitian ini menggunakan data berupa data sumur, data seismik dan beberapa data well report dan mud log yang kemudian difokuskan untuk menganalisis sekuen stratigrafi, elektrofasies, fasies dan fasies seismik serta paleogeografinya. Dari pengolahan data sumur dengan menggunakan metode sekuen stratigrafi didapat dua sekuen pengendapan yaitu sekuen SB2-SB1 dan TAF/SB3-SB2. Analisis elektrofasies dari tiap sumur didapatkan tiga jenis fasies daerah penelitian berupa channel, bar dan shale. Hasil pengolahan data perhitungan sand shale ratio didapat arah pengendapan daerah penelitian umumnya berarah tenggara - barat laut dengan ciri penipisan lapisan sedimen dari tenggara menuju barat laut. Berdasarkan analisis fasies seismik menunjukkan sekuen pengendapan SB2-SB1 berupa fasies channel, delta front dan pro delta, sedangkan sekuen pengendapan TAF/SB3-SB2 berupa fasies delta front dan pro delta. Paleogeografi yang berkembang pada daerah penelitian yaitu pada sekuen SB2-SB1 berupa delta plain, delta front dan pro delta, sedangkan sekuen pengendapan TAF/SB3-SB2 berupa delta front dan pro delta.

T The research area was conducted in RMA Field, South Sumatera Basin, South Sumatera and located in Talang Akar Formation. There are several data that are used in this research to analyze stratigraphy sequence, electrofacies, facies, seismic facies and also paleogeography. They are well log data, 3D seismic data, some mud log data and some well reports. In this area, there are two sequences named SB2-SB1 sequence and TAF/SB3-SB2 sequence based on well log data processing. The result of electrofacies of each well obtained three facies, channel, bar and shale. The deposition direction that occured in this research area obtained by processing sand shale ratio data, the deposition direction is southeast - northwest with the characteristic of sediment layer depletion from southeast to northwest. Based on seismic facies analysis, the sequence of SB2-SB1 deposition facies is channel, delta front and pro delta. On the other hand, the sequence of TAF/SB3-SB2 deposition facies is delta front and pro delta. The paleogeography that developed in this research area was divided into two sequences, the SB2-SB1 deposition sequence is delta plain, delta front and pro delta, and the TAF/SB3-SB2 deposition sequence is delta front and pro delta.
