The Railroad Commission of Texas Tuesday voted unanimously to allow two drilling waste disposal wells to continue operating following investigations earlier this year into whether the wells were contributing to seismic activity in the regions where they operate (see Shale Daily, Sept. 11; Sept. 2). Researchers found that in both cases it was not likely that the wells were causing earthquakes in the area of the Texas towns Azle and Reno. XTO Energy Inc. and Enervest Operating LLC will be allowed to continue operating their respective injection wells.

Australia-based Armour Energy Ltd. has voted in favor of selling a 75% interest in an exploration project in the country’s McArthur Basin to American Energy Partners LP (AELP) (see Shale Daily, Aug. 20). Armour signed a letter of intent to sell 14.99% of its shares and the farm-out rights to the Oklahoma City producer, which is headed by Aubrey McClendon. The agreement allows AELP to explore 21.5 million acres of Armour’s 34 million-acre project. More than 184 million Armour shareholders voted in favor of the transaction versus 10.4 million opposed. Armour recently announced a 66% increase in the McArthur Basin natural gas resource base, which boosted its estimate for prospective resources in the shale play to 57 Tcf from 23 Tcf.
