One of the final acts of the last Fianna Fail government was to award licences to a number of companies to explore for commercial gas in the Northwest Carboniferous Basin (more commonly known as the Lough Allen basin). The Lough Allen Basin is a huge area that covers parts of counties Cavan, Donegal, Fermanagh, Leitrim, Mayo, Monaghan, Roscommon, Sligo and Tyrone. It is an area of 8000 square kilometres in total.
