In the era of hydrocarbon exploration and development, research to identify subsurface hazards potentials and risks need to be done first as an effort to prevent business failures due to planning errors. In the offshore hydrocarbon exploration survey, drilling hazards must be identified first. Among them are shallow gas, shallow channel, pockmark, and man-made objects buried under or lying on the seabed. Survey method with excellent record resolution is required to identify these hazards as clearly as possible. The seismic method is capable of penetrating under the seabed. However, to produce a clearer cross-section, the seismic method needs to be developed into a HighResolution survey and uses a three-dimensional (3D) configuration to display the ability to interpret from all sides. Saka Energy Muriah Ltd through PT Mahakarya Geo Survey has successfully conducted a high-resolution 3D (HR3D) Seismic survey in the Suisen Muriah Block, ~92km NNE from Rembang coast to investigate the hydrocarbon potential and subsurface hazards that may exist. While acquiring, the data’s condition and quality observed by performing QC onboard processing, we can determine the data’s condition and quality when measuring so that the data will be quickly processed and more advanced in onshore-based processing.
