Abstract
This paper presents a structural and stratigraphic interpretation and correlation based on seismic and well data of the Upper Ordovician Muminyat Formation in the El-Sharara oil field of block NC-115 in the Murzuq Basin, southern Libya. The utilization of 3D surveys, which provide three-dimensional representations of structures and thickness, is essential for three-dimensional seismic interpretation. The ultimate goal of the seismic interpretation in this study is to explore the structure and thickness map for Mamuniyat Formation, which lies beneath the surface and study the nature of the rocks in this formation as well as the tectonics, that took place in this formation. In this regard information of detailed geological structure and thickness of the Mumuniyat formation, the relation of reservoir at the El-Sharara oil field to certain sedimentary facies zones is extremely important when developing predictive criteria for searching for hydrocarbons, as well as choosing methods to increase oil recovery.
