Following the company’s drilling campaign, it said that Mzia was the second giant gas discovery, after Jodari, in BG Group’s acreage offshore Tanzania, with 13.3mn cubic metres of total gross recoverable resources.

According to the UK-based explorer, the Mzia-3 appraisal well, drilled approximately six kilometres north of the original Mzia-1 discovery in 1,780 metres of water, has been cored and logged.

“Results confirm the reservoir sands are extensive and of similar quality to those found in the Mzia-1 and Mzia-2 wells. In addition, the gas-down-to level proven in Mzia-3 is around 100 metres deeper than that of Mzia-2,” it added.

In the northern part of the country, BG Group is also currently carrying out detailed technical analysis of the Block 4 discoveries namely Chewa, Ngisi and Pweza, which were also appraised and tested in the campaign. The total gross recoverable resources in the block now estimated around 14.1mn cubic metres.

Chris Finlayson, BG Group’s chief executive, said, “We have sufficient resources for a two-train LNG project in Tanzania. The aim of our appraisal programme now is to optimise the future development plan and place the most economic gas into the proposed project first to extract the most value across the chain.

"Onshore, BG Group and its partner Ophir Energy, together with the partners in Block 2, Statoil and ExxonMobil, are continuing to make good progress in the assessment of a multi-train LNG project. We look forward to the Tanzanian government’s announcement of a decision on the location of an onshore site for an export facility.”

BG Group as operator has a 60 per cent interest in Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy holding 40 per cent share.
