tight gas
n.— «Shell has agreed to pay almost C$6bn ( £3bn) for a small Canadian gas company heavily involved in the production of difficult-to- exploit gas reserves. The price for Calgary-based Duvernay Oil, founded just seven years ago, surprised the market but Shell is anxious to build up assets of what the industry calls “tight gas” in western Canada, reports the Telegraph.» —“Tuesday newspaper round-up: Alliance & Leicester, Kazakhmys, Shell” City A.M.
