 Santos acquired the Comet Ridge coal seam gas project comprising Fairview and 4,000 square kilometres of exploration acreage in 2005 through the acquisition and subsequent merger of Tipperary Corporation's Australian assets into the Santos gas portfolio.The remaining participants, which include origin parties, hold a combined net revenue interest of 22.93%, and a working interest of 20.5%.The discovery well, the Fairview 1, was drilled in August 1994, followed by a number of other wells which subsequently began dewatering to establish the technical and commercial viability of coal seam gas.
