Abstract

The workflow for seismic sequence stratigraphic analysis includes 3D seismic interpretations, conditioning and filtering of 3D seismic volumes, interactive interrogation of seismic facies, calibrating well-log electrofacies and core data, and transforming interpreted facies into the Wheeler domain for sequence stratigraphic interpretations. The forward stratigraphic model was built by inputting interpreted key structural depth grids, gross depositional environment maps (GDE), lithofacies, and wireline-log data of selected key wells, and paleoenvironmental parameters such as paleobathymetry, subsidence/sedimentary supplies, and environmental considerations (e.g., wind direction and water depth). Results from this integrated approach revealed details regarding hiatuses, maximum flooding surfaces, and spatial distribution of source rocks, reservoirs and seals through time. In particular, the forward stratigraphic modeling results have provided additional insights for predicting grainstone shoaling complexes, and source rock deposition and distribution within Tuwaiq Mountain and Hanifa sequences.
