The company said a drill stem test on the original natural gas discovery well confirmed excellent quality of the Tertiary reservoir.
BG Group President and Asset General Manager for East Africa, Mr Derek Hudson, also said they are progressing their work on identifying suitable sites for a potential onshore Liquidified Natural Gas (LNG) terminal.
According to the announcement, the drill stem test on the Jodari-1 well, the first in deep water off Tanzania, flowed at a maximum rate of 70 million standard cubic feet of natural gas per day, constrained by testing equipment.
“The results showed better than expected reservoir properties, including high connectivity and demonstrated that development wells could produce at higher rates,” it said.
The drill stem test was conducted on one of the three successful wells on the Jodari field, in 1,150 metres of water and approximately 39 kilometres off the coast of southern Tanzania.
BG Group’s Chief Executive Officer, Mr Chris Finlayson said: “The completion of a multiwell exploration and appraisal programme on the Jodari field within a year of the original discovery is a significant achievement and a credit to our team and partners including Ophir Energy and the Government of Tanzania.
“It builds upon our run of exploration success offshore Tanzania and further demonstrates the potential of BG Group’s acreage. “Results from the Jodari-1 test have greatly improved our understanding of the sub-surface, reducing uncertainty as we progress our options for commercialising the resource through a potential liquefied natural gas export project and our domestic market obligations,” Mr Finlayson said.
