LONDON (Alliance News) - BG Group PLC said Wednesday that the results from its second drill-stem test on the Mazia discovery in Block 1, offshore Tanzania, has provided further support for a hub development to supply a potential onshore liquefied natural gas project.
The exploration and LNG company said the drill-stem test on the Mzia-3 appraisal well was drilled in approximately 1,800 metres of water around six kilometres north of the original Mzia-1 discovery.
BG Group said the test included sustained gas production at a maximum flow rate of 101 million standard cubic feet per day, equivalent to approximately 17,000 barrels of oil equivalent per day.
"The excellent results from this latest drill-stem test further reduce reservoir risk, a critical factor as we progress design of the upstream production facilities and infrastructure. Also, the Mzia-3 DST, along with previous appraisal activities, supports our efforts to optimise the value of a development across our Block 1 discoveries," said Sami Iskander, BG Group's chief operating officer.
The drill ship, the Deepsea Metro-1, will now move north to complete the exploration and appraisal programme on the Block 4 discoveries by drilling the Kamba-1 well, said the company.
BG Group has a 60% interest in, and is operator of, Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy PLC holding 20% and Pavilion Energy 20%.
Mzia was discovered in 2012 and is a multi-layered field of Upper Cretaceous age with a gross gas column in excess of 300 metres. The Mzia and Jodari discoveries in Block 1 are estimated to hold around nine trillion cubic feet of total gross recoverable resources, said BG Group, with around 15 trillion cubic feet of total gross recoverable resources, around 2.5 billion barrels of oil equivalent, across Blocks 1, 3 and 4.
