Abstract
Subsurface geologic studies brought to light an unrecognized and unreported prominent horst which is herein named ‘Inferred Horst.’ This horst trends NW-SE, links the Southern shelf with the Beda Platform, and separates the Hagfa Trough from the Dor Alabid and Bu Tumayam Trough. This geologic finding relies mainly on data available from wells drilled in the area. Therefore, it is very essential to be verified and supported by geophysical evidence to confirm the presence or otherwise of this horst.
Seismic data along seven selected profiles covering nearly 200 line kilometers, were studied alongside with the completion, sonic and gamma ray logs of few wells. The study gave clear indications of the presence of a NW-SE striking inferred faults bordering the Inferred Horst. It appears to be a composite tectonic unit formed by minor positive and negative blocks. The Inferred Horst is concluded to be prospective and seems to offer good locales for large accumulations of hydrocarbons.
