The Murzuq Basin is an intracratonic basin located in the South and Southwest (SW) Libya. Glacial Ordovician sandstones are the primary reservoir. However, identifying the top of the upper Ordovician reservoir and the interpretation of intra-Ordovician sequence directly from seismic using conventional methods are well-known challenges in the explor...

... applying this method, we were able to quickly identify the two main Ordovician unconformities and their internal zones.the upper Ordovician unconformity illuminated by sizeable thin separation followed by series of tight and larger separations with Vp curve to the right ( Figure 12). While the second dirty zone of the upper Ordovician reservoir named M1 ( Figure. ...

... maps of the Basement, Base Tanezuft and Top Tigouentourine were generated from the interpreted 2D seismic lines. The Base Tanezzuft structure map showed the highest relief in North, West and the central part of the study area, and the lowest relief in the south and south-east parts (Figure. 12). The identified structures may fall into two main trap types: Paleogeomorphologic traps that were generated as a result of glacial erosion during the Ordovician time when the melting glaciers cut through the Hawaz formation producing the erosion of its upper part. The Hawaz Formation then overlain by either the younger Silurian ...
