The well spudded on August 10 and has a target depth of 3200m.
Reeb-1 is about 35km east of Oil Search’s Al Magrabah-1 well. The primary target is the Qishn Clastics, with secondary targets in the fractured-karstified Saar and Naifa formations, Kuhlan sandstone and weathered-fractured metamorphic basement.
Participants in Block 35 are Oil Search 32.5% (operator), Virgin Resources 37.5%, Arc Energy 15%, MND 10% and the Yemen Company 5%.
The Yemen Company is carried by the other joint venture participants.
Elsewhere in Yemen, Oil Search and operator DNO ASA are drilling ahead on the Thoub-1 well in Block 43.
About 8km east of the partners’ Nabrajah field, the well is targeting a tilted fault block at the primary Qishn Clastics objectives and four-way dip closure at the secondary targets in the fractured-karstified Saar and Nayfa formations.
The prognosed total depth is 3300m.
The participants in Block 43 are: DNO ASA 56.67% (operator), Oil Search (Yemen) 28.33% and The Yemen Company 15% (carried).
Meanwhile, in Egypt, Oil Search reports that over the week, the first of four planned drill stem tests in the Rana-1 well was completed.
During the main flow period the well flowed 39.5 degree API oil with negligible water and a gas-to-oil ration of 1044 standard cubic feet per barrel from the Kharita formation, at a stabilised rate of 538 barrels of oil per day on a small (16/64-inch) choke.
Three more zones will be tested, based on cased hole log evaluation that indicates further potential oil bearing intervals in the Bahariya formation.
Fishing operations have delayed the next test.
Rana-1 is in the East Ras Qattara concession in Egypt’s Western Desert, about 12km southeast of the recently drilled Ghard-1 discovery.
Rana-1 is third successive discovery of oil in the highly prospective East Ras Qattara block and the strong flow rate from the Kharita formation represents the third productive horizon identified in the area.
The participants in Rana-1 are: Sipetrol International 50.5% (operator) and Oil Search 49.5%.
