Tembo-1 exploration well drilling complete in Mozambique

Oilfield Technology,

Independent, East Africa-focused oil and gas company Wentworth has announced that drilling operations of the Tembo-1 well have now completed and a natural gas discovery has been made in Cretaceous aged sands. The well was drilled to a total depth of 4553 m (4401 m true vertical depth subsea) and reached TD in Jurassic aged sediments.

Petrophysical analysis of the Cretaceous section indicates 11 m of natural gas net pay. Natural gas and some condensate was recovered by modular formation dynamics testing (MDT) confirming the petrophysical analysis. The Onshore Rovuma partners do not plan any further evaluation of the Tembo well at this time but will assess all the data recovered from this well to determine the potential commerciality of this discovery.

The Tembo-1 well has been plugged and abandoned and the drilling rig is now being mobilised to the Kifaru-1 well location. It is expected that the Kifaru-1 well, which is approximately 10 km south of Wentworth's Mnazi Bay Concession in Tanzania, will spud in 1Q15. This well is targeting Miocene sands, similar to the reservoirs in the Mnazi Bay and Msimbati gas fields, as well as Eocene and Cretaceous sands.

Wentworth holds a 13.64% participation interest in exploration operations and an 11.59% participation interest in development and production operations of the Rovuma Onshore Concession in Mozambique. Anadarko Petroleum Corporation is operator.

2015 a transformational year

Bob McBean, Executive Chairman, commented: "The Tembo-1 well was an exciting well and has provided additional information about the Rovuma basin. We look forward to our continued exploration in the Onshore Rovuma Block with the spudding of the Kifaru-1 well. With our imminent gas production in southern Tanzania on track, 2015 should be a transformational year for Wentworth".
