Kazakhstan-focused explorer Roxi Petroleum has increased the potential of its majority-owned BNG field after uncovering new hydrocarbon shows.
Last month the A5 – the first deep well in the asset – detected oil and gas shows in the target middle Carboniferous formation at a depth of 4,332 meters over a 12-metre core taken.
This potential was upped earlier this month as another 18-metre oil and gas-bearing core was taken.
Today, the company announced additional 18 meters identified at a depth between 4,365 and 4,383 meters, of which 1.6 meters was recovered.
The new find increased the aggregate thickness of the gross oil-bearing interval in BNG to at least 51 meters.
The company is now looking to determine the full extent of the oil-bearing interval by drilling and logging, before putting A5 on a flow test.
“At more than 51 meters the gross oil-bearing interval at BNG Well A5 now exceeds our initial expectations,” said Clive Carver, Roxi Petroleum’s chairman.
“We remain excited by the potential of the deep horizons at the BNG Contract Area and look forward to the results of the flow test.”
Roxi holds a 58.4% interest in the licence, located in the western part of Kazakhstan, on the edge of the Mangistau Oblast.
The BNG drilling programme for the rest of 2014 sets out drilling of a further five shallow wells and in the first half of 2015 a further two deep wells.
