The Thai company said the Maple-2 appraisal well flowed at a rate of 30 million cubic feet of gas per day and 696 barrels per day of condensate during testing.
It reached total depth of 4150 metres on 1 July 2012.
“The well results enhance our knowledge of the resource and deliverability of the Cash-Maple field and are significant information to further justify the project’s economic viability,” said PTTEP chief executive Tevin Vongvanich.
PTTEP intends to use the Cash-Maple field as feedstock for a floating liquefied natural gas vessel with capacity of 2 million tonnes per annum of LNG.
The FLNG development is currently in the engineering phase.
