C Cekungan sumatra tengah merupakan cekungan sedimen tersier krusial di indonesia. lapangan rj yang berada di cekungan sumatra tengah memiliki data yang menarik diantaranya data log dan batuan inti yang mampu memberikan informasi mengenai karakteristik litologi, lingkungan pengendapan, dan fasies sementara dipmeter memberikan informasi mengenai arus purba reservoir batupasir a, b, dan c dan potensinya masih belum sepenuhnya diperoleh. penelitian ini bertujuan untuk mengetahui karakteristik litologi, fasies, dan arus purba reservoir batupasir a, b, dan c formasi bekasap, lapangan rj cekungan sumatra tengah. penelitian ini dilakukan dengan menggunakan metode integrasi analisis data log,deskripsi batuan inti, dan analisis dipmeter. penelitian ini menghasilkan karakteristik litologi reservoir batupasir a dengan karakteristik litologi batupasir,kaolinit, putih, ukuran butir halus sampai kasar, tidak mengandung calcareous,sortasi buruk, reservoir batupasir b memiliki karakteristik litologi batupasir interlaminasi dengan batulanau, putih keabuan, ukuran butir sedang hingga halus,tidak mengandung calcareous, kekompakkan keras, sortasi baik, dan reservoir batupasir c memiliki karakteristik litologi batupasir, very silty, clayey, glaukonit melimpah, abu-abu, hingga abu-abu muda, ukuran butir sangat halus, struktur calcareous, sortasi baik. reservoir batupasir a memiliki tiga jenis fasies yakni tidal bar axis, tidal bar off-axis, dan tidal bar margin, reservoir batupasir b memiliki dua jenis fasies yakni tidal bar off-axis dan tidal bar margin, dan reservoir batupasir c memiliki dua jenis fasies yakni tidal bar off-axis dan tidal bar margin. reservoir batupasir a memiliki arus purba dominan arah timur laut-barat daya, dengan pola arus polymodal reservoir batupasir b memiliki arus purba dominan timur laut-barat daya dengan pola arus polymodal, dan reservoir batupasir c memiliki arus purba dominan arah timur laut-barat daya dengan pola arus polymodal, pola arus reservoir batupasir a, b, dan c menunjukkan bahwa lingkungan pengendapan reservoir batupasir a, b, dan c berada pada lingkungan tidal bar.
T The central sumatra basin is a crucial tertiary sedimentary basin in indonesia. the rj field in the central sumatra basin has interesting data, including log data and core samples that provide information on lithological characteristics,depositional environments, and facies, while dipmeters provide information on the paleocurrents of sandstone reservoirs a, b, and c, the potential of which has not yet been fully explored. this study aims to determine the lithological characteristics, facies, and paleocurrents of sandstone reservoirs a, b, and c in the bekasap formation, rj field, central sumatra basin. this study was conducted using a method that integrated log data analysis, rock core description, and dipmeter analysis. this study results in the lithological characteristics of sandstone reservoir a with lithological characteristics of sandstone, kaolinite, white, fine to coarse grain size, no calcareous content, poor sorting, sandstone reservoir b has lithological characteristics of interlaminated sandstone with mudstone, grayish white, medium to fine grain size, no calcareous content, hard compactness, good sorting, and sandstone reservoir c has lithological characteristics of sandstone,very silty, clayey, abundant glauconite, gray to light gray, very fine grain size,calcareous structure, and good sorting. sandstone reservoir a has three types of facies, namely tidal bar axis, tidal bar off-axis, and tidal bar margin. sandstone reservoir b has two types of facies, namely tidal bar off-axis and tidal bar margin,and sandstone reservoir c has two types of facies, namely tidal bar off-axis and tidal bar margin. sandstone reservoir a has a dominant paleocurrent in the northeast-southwest direction, with a polymodal current pattern, sandstone reservoir b has a dominant paleocurrent in the northeast-southwest direction with a polymodal current pattern, and sandstone reservoir c has a dominant paleocurrent in the northeast-southwest direction with a polymodal current pattern. the current patterns of sandstone reservoirs a, b, and c indicate that the depositional environment of sandstone reservoirs a, b, and c was in a tidal bar environment.
