US oil and gas explorer Anadarko Petroleum has expanded its recoverable natural gas estimate for the Barquentine-3 appraisal well, offshore Mozambique.
The appraisal well encountered more than 662 net feet of natural gas pay, increasing the estimated recoverable resource range from 15 trillion to over 30 trillion cubic feet (tcf).
The well has an estimated 30-50tcf of natural gas in place.
Anadarko CEO Jim Hackett said that this could be one of the most important natural gas fields discovered in the last ten years, with significant long-term benefits for Mozambique.
"The positive results of each appraisal well that we have drilled and analysed have continued to increase our estimate of recoverable resources and natural gas in place on our block" said Hackett.
