چکیده
A sedimentary basin is a depression where sediment deposits accumulate and can act as a reservoir for the sedimentation and maturation of sediments containing hydrocarbons. The Bengkulu Basin is one of the forearcs in Indonesia. The Bengkulu Basin is one of the basins with the potential to have hydrocarbon reserves marked by an oil show in the Padang Capo village. Exploration to find a basin or hydrocarbon trap can be done using the gravity method. This method is often used to study the structure, bedrock, rock intrusion, and sedimentary basins based on variations in the earth's
gravitational field due to lateral density differences which are known as anomalies gravitational. Determination of the existence of a hydrocarbon trap structure is carried out by derivative analysis, namely First Horizontal Derivative (FHD) and Second Vertical derivative (SVD) graphs and 2D modeling using forward modeling. The results of the analysis of the FHD and SVD graphs with 2D modeling show synchronous results. Where the analysis of the FHD and SVD graphs in the study area found many fault structures and folds. The study area is dominated by the fault type of thrust fault. In the 2-dimensional modeling of the research area where there is an oil show, it is found that there is a rising fault structure and the presence of anticline and syncline structures that could act as hydrocarbon traps.
