BG strikes more gas offshore Tanzania

BG Group has made another gas discovery on its latest exploration well offshore Tanzania, adding to the potential for LNG development in the country. 

The Mkizi-1 well in Block 1, was drilled by the Deepsea Metro I drillship in 1301m deep water, between the existing Mzia and Jodari discoveries. 

The announcement follow's the Ngisi-1 well discovery and an upgrade on the Chewa gas field estimates, both on Block 4, offshore Tanzania, earlier in July.  

BG Group owns 60% equity and is operator on Blocks 1, 3 and 4, with partner Ophir Energy holding the remaining 40%. 

Ophir said the Mkizi-1 well found natural gas in three reservoir intervals, within a Tertiary-aged stacked channel complex. 

Total net pay was 33m and reservoir quality was high, with all three intervals showing excellent porosities and permeabilities, the company said. 

Estimates for the mean recoverable resource from the discovery are in-line with Ophir’s pre-drill expectations of 0.6 TCF, it added.  

The Deepsea Metro I will now move on to drill two appraisal wells, including a drill stem test (DST), on the Pweza discovery in Block 4.

This will be the first DST on a number of Block 4 discoveries.
