Evaluation of the wireline logging has confirmed a gross gas interval of 49m and a minimum gross oil interval of 39m confirmed from sampling and pressure measurements. The minimum hydrocarbon column (confirmed) of 88m thickness has an overall net reservoir sand ratio of approximately 45%.

Below the confirmed oil zone there is an additional 73m section with poor reservoir quality which the partners consider may be oil bearing.

Additionally pressure measurements in the oil and water zones indicate that the oil-water contact may be at or below the water sand, which could indicate a potential gross oil column thickness in excess of 100m.

On the basis of a possible inferred oil column of over 100m, Hardman Resources (21.6%) has estimated that the Tiof Field has the potential to contain in excess of 200 million barrels oil recoverable. However, the true oil water contact and potential size of the Tiof discovery will only be determined by the drilling of one or more appraisal wells.

The Tiof well was designed to test an independent structural closure within a Miocene channel sandstone system, believed to be of similar age to the oil and gas reservoirs at Chinguetti and Banda. The Tiof Prospect is also adjacent to and associated with a salt diapir and has a closure of approximately 50sq.kms (about four times larger than at Chinguetti).

Upon completion of the drilling operations at Tiof, the drillship "West Navigator" will sail to the Poune Prospect location, which is located 27kms northeast of the Tiof Field and 48kms north of the Chinguetti Field in PSC Area B.

Participants in the Tiof well and PSC Area B are Woodside Mauritania (operator) 35%, AGIP Mauritania BV 35%, Hardman Resources 21.6%, Fusion Mauritania B 6%, Roc Oil (Mauritania) Company 2.4%.
