Identifikasi Akuifer untuk Penentuan Rencana Titik Sumur Bor Produksi menggunakan Metode Geolistrik 2D di Perkebunan Kelapa Sawit Kabupaten Tanah Bumbu

Abstract

The aquifer layer has been identified based on resistivity values using the Schlumberger configuration geoelectric 2D method in the Tanah Bumbu Oil Palm Plantation. Measurements were made as many as four lines each with a length of 675 m. The purpose of this study was to determine the 2D crosssectional model and the type of lithology as well as the depth and thickness of the aquifer layer based on the resistivity value. Based on the results of the study, the types of lithology obtained were three layers, namely clay with a resistivity value of 12-29.5 Ωm, clay sand with a resistivity value of 29.5-71.5 Ωm and sand with a resistivity value of 71.5-190 Ωm. From the results of the nterpretations indicated, the planned wellbore points are located on all trajectories with successive depths and thicknesses of 60-130 m and 70 m, 72-90 m and 18 m as well as 77-145 m and 68 m.
