SEQUENCE STRATIGRAPHIC STUDIES
We at Geoterrain apply integrated multidisciplinary sequence stratigraphy approach to hydrocarbon exploration, with the aim to increasing our ability to predict hydrocarbon occurrence in the subsurface of frontier area, to improve and continue to add positive values to the knowledge of our clients’ assets and portfolio. This tool helps in understanding stratigraphic relationships by providing a stratigraphic hierarchy based on observational criteria and also assists in providing a geologic framework, to create play maps that depict spatial and temporal stratigraphic variation in terms of gross depositional environment setting. It also allows for interpretations of potential source rocks and reservoir rocks in both frontier areas, having seismic data but limited well control and in more mature hydrocarbon provinces.
Sequences tend to show cyclicity of changes in relative sea level and widespread unconformities, processes of sedimentation and sources of sediments, climate and tectonic activity over time.
We in conjunction with our client subject matter experts help in the prediction of reservoir continuity which is currently a key question in mature hydrocarbon provinces where sequence Stratigraphy is being applied.
Physical description and geometric relations of seismic reflections or rock units guide interpretation of the rock record, not conceptual models of sea-level variation or age-duration and the system tracts provide a natural scheme to classify reservoirs.
