The research focused on 3D seismic interpretation for the evaluation of depositional environment in North Malay Basin. Seismic interpretation used to identify the petroleum elements that have structural or stratigraphic traps, geological structures, and hydrocarbon plays. Depositional environment of sedimentary rocks that form from a graded series that has been undergo with structural geology that led to the formation of the petroleum system. The hydrocarbon will enter the trap in the petroleum system that form a reservoir. Separating time-depositional units based on the identification of irregularities in seismic patterns is a component of a seismic sequence analysis. By locating their borders, depositional sequences and systems tracts are identified on seismic sections. Since each non-conforming sequence has a unique depositional system, analysis of depositional systems is performed. Direct Hydrocarbon Indicator (DHI) was investigated through the interpretation of isochron and isopach maps using Petrel software. From a seismic raw image, Petrel is utilized to extract time and depth information. Stratigraphic study was carried out after determining the pertinent seismic attributes. Correlation between log data and seismic data was carried out to validate the validity of the interpretation. The results would be interpreted to reveal the local geological formations and hydrocarbon plays.
