| Abstract | ||
| Structural interpretation is considered as a conventional method for oil exploration and commonly used. The use of unconventional methods could lead to achieve significant results and reduce the drilling risk. The subsurface image is completely objective, while merging the unconventional tool, like seismic attributes and the conventional seismic interpretation workflow, to highlight the structural elements, which matched together. Also to identify the general prospective area of interest, the multi-dimensional seismic attributes computation, along with the use of time slices, are both independent of interpretation.This means that no prior interpretation is necessarily required and no interpretational bias to the seismic attributes results. Seismic attributes were used to enhance fault image and enhance the continuity of picked horizons. The main objective of this paper is to determine the structural tectonics of the study area using, the conventional method combined with the unconventional methods with respecting the geological backgroundof the study area. Upon the horizon flattening, the encountered pre-Cretaceous faults within the vertically animated three dimensional seismic cube were better imaged and picked carefully. Drilled Jurassic plays within Southwest Abu Sennan (SWS) area were dry, due to low structural plays during the Jurassic before the Late Cretaceous tectonic event which brought the Jurassic rocks high as per the current day situation. AR/”G” Member and Khoman Formation depth structure contour maps were generated to show the main fault sets, a dominant northwestsoutheast set and a set trending northeast-southwest due to Syrian arc structure system. | ||
