Gas reserves update NW Natural received approval in the second quarter of 2011 from the Public Utility Commission of Oregon (OPUC) to participate in a joint venture with Encana Oil & Gas (USA) Inc. to develop gas reserves on behalf of NW Natural’s utility customers. The company is expected to invest approximately $45-55 million a year over a five-year period, for a total investment of about $250 million. The investment will cover a portion of the expected drilling costs in exchange for working interests in two sections of the Jonah Field in Wyoming. The drilling area includes both future and currently producing wells. Encana began drilling in May 2011, and the company is currently receiving gas from its interests in a section of the gas field. NW Natural’s investment at Sept. 30, 2011 was $30.9 million.
