| Abstract | ||
| A new gravity and seismic survey along a profile length (70 Km) carried out at the area of exploration Block- 11 in Al- Najaf desert, southwest Iraq. The obtained gravity and seismic value compared with the previous available data that achieved by IPC and OEC for gravity and seismic data respectively. The difference between the new gravity profile and the old one is mainly in small anomaly not more than (14 %) that related to shallow depth levels and presents through power spectrum analysis. Previously, Ghulaissan-1 well which drilled in (1960) depend on a positive gravity and magnetic anomaly interpret, which is considered as an anticline structure in sub surface. It did not indicate any hydrocarbon shows after drilling, the integration study shows, that the positive anomaly appear in gravity record may be results from extension of presence thick Ophiolites and syn- tectonic gabbro. | ||
