It is rare that the correctness (or incorrectness) of an interpretation can be ascertained, because … This course follows a seismic interpretation workflow, integrating regional geology, wells, and 2D and 3D seismic data to perform structural and stratigraphic interpretation and mapping. A key first step in seismic interpretation is to use well logs and cores to identify the three types of stratal interfaces that exist in geologic intervals of interest: Flooding surfaces; Maximum flooding surfaces; Erosion surfaces; Back to top. Even though a good workflow for sand mapping was established, the hydrocarbon identification remained a challenge. We focus on the development and quantification of ‘measure-ment uncertainty’ associated with seismic interpretations, and integrating this into subsurface modelling workflows.
