IGas Energy has announced that it has increased average gas production at its Doe Green site in Cheshire by around 40%.The increase was achieved following the implementation of measures to improve the "de-watering process" at one of the site's wells.The group has been steadily producing gas and generating electricity for over a year from Doe Green, and as a consequence of positive production, it has now applied for planning permission to extend the site."The materially improved production rates are a significant step in demonstrating the commerciality of the gas held in our acreage and the Board is very encouraged by the results," said chief executive Andrew Austin.
