Many faults were encountered in the Hout Field wells which are located in the Arabian Oil Company's concession area in the Arabian Gulf (Persian Gulf).
These faults were analyzed mainly on the basis of Schlumberger's Continuous Dipmeter results and other well data, and interpreted to be the radiated rupture-fults which occurred on the surface formations with small wedge-shaped blocks slipped down into the rupture bottom at the time of upheaval movement which formed the Hout anticlinal structure at the end of Middle Cretaceous.
The horizontal distribution manner of faults is a radial form with a center on the crest of the structure. The bottom of each couple of ruptures, that is, each wedge-shaped block, seems not to reach the Ratawi Horizon. So, the rupture faults are limited to the Middle Cretaceous forma tions.
Then, these faults never give any affect to the Ratawi reservoir continuity and oil accumulation but give some affects to the Middle Cretaceous reservoirs.
