Wentworth revealed that, along with its partners, a gas bearing zone was exposed at between 1,106 and 1,109 metres and that they were now conducting testing operations.

Located in the Mnazi Bay Concession in the south-east of the country, Ziwani-1 was first spudded in February 2012 and has since been drilled to a depth of 2,671 metres.

Wentworth announced that it had encountered gas shows within the well in April 2012 and has confirmed that full logging operations have also been completed on the site.

“The zone to be tested is a new reservoir interval, not previously encountered in the Mnazi Bay Block,” said the company in a statement.

“The reservoir is a clean limestone of Pliocene age which exhibited strong gas shows during drilling (4.3% Total Gas).

“Petrophysical interpretation of wireline logs indicates a pay zone with 17 per cent porosity and 78 per cent hydrocarbon saturation indicating good reservoir quality,” added the firm.

It will now conduct a Drill Stem Test to establish the flow rate possible from this reservoir interval.

“There can be no assurance that any flow rate achieved will prove to be commercial, but the information acquired is expected to be valuable in respect of knowledge of the basin for further exploration,” Wentworth revealed.
