Drilling has started on high impact Tembo well in Mozambique says Wentworth

Drilling has commenced on the keenly anticipated and potential new frontier Tembo-1 well in the Rovuma Onshore Concession in northern Mozambique, Wentworth Resources said. Wentworth has an 11.59% net interest in the well, where Anadarko in the operator. The Tembo-1 well is targeting mid-Cretaceous sands with secondary targets in the upper Jurassic to a total depth of 4,250 metres with a 60 to 90 day schedule to complete. Two wells have been drilled elsewhere in the Rovuma Onshore Concession so far with one of these, Mocimboa-1, recording oil and natural gas shows in the Cretaceous zone. Mocimboa is 17km northeast of Tembo-1. Geoff Bury, Wentworth’s managing director, said Tembo-1 would test Cretaceous and Jurassic sands and is the first of two wells that Wentworth will be participating in at the concession over the next six months. Tembo is a high impact frontier well and, if successful, could add significant new oil or natural gas resources for Wentworth and open up an entirely new play fairway, he added. The Tembo consortium includes France’s Maurel et Prom, Thailand’s national oil company PTTEP, and Mozambique’s national oil company ENH, and is estimated to contain about 1.2bn barrels of in-place oil or 2.4trn cubic feet (Tcf) of gas. On a P50 basis, this equates to 756mln barrels and 1.6Tcf.

The Rovuma Onshore Block is a 13,494 sq km area in the Rovuma Basin in north eastern Mozambique. The block is adjacent to Wentworth Resources’ Mnazi Bay Concession. In 2005, Wentworth Resources along with oil major Anadarko Petroleum, won an exploration license in this block.

Wentworth Resources said the potential oil play within the Tembo prospect in the license is 1,205mn stock barrels. The Tembo prospect is the first one that Wentworth Resources will drill in Mozambique.

In Tanzania, Wentworth Resources said it is negotiating with its partners — Maurel et Prom and Tanzania Petroleum Development Corporation — in the Mnazi Bay Concession for commercial sales of gas.

The Mnazi Bay Concession covers a 756 sq km area in south-eastern Tanzania, bordering Mozambique. In 2005, Wentworth Resources re-entered a shut-in well and drilled two appraisal wells and one exploration well in this area. Wentworth Resources has two gas plants in the region, with about 18.03bn cubic metres of prospective gas resources.
