Geomorphological Geometries and High-Resolution Seismic Sequence Stratigraphy of Malay Basin’s Fluvial Succession

This study identified the Pleistocene depositional succession of group (A) (marine, estuarine, and fluvial systems) Melor Inas fields in central Malay Basin from seafloor to approximately −507 ms (522 m). During last few years, hydrocarbon exploration has moved focus on stratigraphic traps, specifically those that existed with channel sands. These traps motivate carrying out this research image locate these kinds traps. It can be difficult determine if closely spaced-out channels belts exist within several seismic sequences map-view proper sequence geomorphic elements surfaces cross lines, or probably reinforce auto-cyclic aggregational stacking avulsing rivers precisely. analysis overcomes challenge by combining well-log three-dimensional (3D) data resolve deposition discontinuities’ considerable resolution. Three-dimensional volume high-resolution two-dimensional (2D) sections wells were utilized. A stratigraphy framework three main (3rd order), four Parasequences sets (4th seven (5th order) have been established. The time slice images at consecutive two-way times display single meandering ranging width 170 900 m. Moreover, other geomorphological perfectly imaged, such as interfluves, incised valleys, chute cutoff, point bars, extinction surfaces, providing proof rapid growth transformation deposits. 2D Cosine Phase attributes facilitated identifying reflection terminations against amplitude. Several continuous discontinuous channels, marine sediments through addressed. whole series reveals almost all systems lay valleys each sequence’s bottom bars. degradational patterns are characterized no evidence aggradation. aggradation stage is restricted sedimentation incursions. 3D description deposits permits distinguishing facies abandoned mud sand bar channel, which filled muddy deposits, may function horizontal barriers baffles might isolate reservoir body into separate storage containers. 3rd, 4th, 5th orders established for studied succession. essential imaged utilizing attributes.
