The TAGS is located in a N-S oriented anticline, with faults part of a flower structure acting as hydrocarbon migration paths, and consists of two distinct formations based on facies. The fluvial TAGS Sandy, which consists of 4 different units, has compartmentalization in especially the meander deposited Sandy 2 and Sandy 4 units whilst Sandy 1 and 3, deposited coastal sabkha and by a braided river system respectively, show excellent connectivity. The coastal sabkha Upper TAGS, consisting of 7 units, shows excellent connectivity for Upper 1, 3, 5 and 7 in its sheet sands except for the deltaic deposited Upper 2 which is highly compartmentalized. The Upper 4 and 6 claystones might act as additional hydrocarbon seals to the overlying Liassic evaporites. A conceptual static reservoir model was created in Petrel to learn more about the size, shape and spatial distribution of the compartments. This was done by creating correlation panels parallel and perpendicular to the SW-NE orientation of the TAGS channel belt. Stratigraphic interpretation based on gamma ray, density and sonic logs as well as core photographs was used to divide the TAGS formation into separate units which were linked by reoccurring claystone intervals. This provided an insight into local fluvial channel belt shifts, mean sea level change and humidity levels. A 3D model was created of these units which was consequently used to estimate the Gas Initially In Place (GIIP) volume.
