The Trees Oil Company v. State Corporation Commission

Chesapeake Operating Inc. sought to unitize adjacent, vertically separated oil reservoirs connected by well bores and use water flooding to boost production across the unit, with the overwhelming majority of affected owners approving; The Trees Oil Company (plaintiff), owner of a boundary well, objected to having its well included and challenged Chesapeake's forced-pooling application before the Kansas Corporation Commission (defendant). Trees argued the statute's definition of "pool" -- a "single and separate natural reservoir" with a single pressure system -- couldn't cover two distinct reservoirs, while Chesapeake showed the reservoirs already had commingled production and good pressure communication across the proposed unit, and that excluding Trees's well would let thousands of barrels of oil migrate out of the unit to Trees's benefit without cost. The Commission approved forced pooling; the district court affirmed, and Trees appealed.
