Mzia-3 Flows 101MMscf/d, Affirms Tanzania’s LNG Potential

BG Group has completed a drill stem test (DST) of the Mzia-3 appraisal well, recording gas production at a maximum flow rate of 101 million standard cubic feet per day (MMscf/d), equivalent to approximately 17000 barrels of oil equivalent per day (BOEPD). It is the second drill-stem test (DST) to be completed on the Mzia discovery in Block 1, offshore southern Tanzania.

The British explorer says the results “provided further support for a hub development to supply a potential onshore LNG project”.

Mzia-3, drilled in approximately 1800metres of water around six kilometres north of the original Mzia-1 discovery.

In May 2013, BG Group announced a test on the Mzia-2 well, the first done on a Cretaceous discovery in deep water offshore Tanzania, had flowed at an equipment-constrained rate of 57 mmscfd, or around 9500 boed.

Sami Iskander, BG Group’s Chief Operating Officer, said: “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 optimize the value of a development across our Block 1 discoveries.”

Mzia, discovered in 2012, is a multi-layered field of Upper Cretaceous age with a gross gas column in excess of 300metres. The Mzia and Jodari discoveries in Block 1 are estimated to hold around 9 trillion cubic feet (tcf) of total gross recoverable resources, with around 15 tcf of total gross recoverable resources, around 2.5 billion boe, across Blocks 1, 3 and 4.

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.

BG Group has a 60% interest in, and is operator of, Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy holding 20% and Pavilion Energy 20%.
