An interesting case has recently been filed in Louisiana challenging the authority of the Louisiana Department of Conservation to approve pooled units containing multiple wells. In Gatti et al. vs. State of Louisiana, et al., Number 589350, Division 23, filed in the 19th Judicial District Court in East Baton Rouge Parish, the plaintiffs sued the State Department of Conservation and several operators in the Haynesville field, including Chesapake, Encana, Exco, Conoco Phillips, Petrohawk, SWEPI, EOG, Questar, Forest and XTO, claiming that the Department of Conservation was routinely allowing the drilling of "alternate unit wells" on previously established units, in violation of Louisiana law. A copy of the petition may be found here.

Louisiana has a forced-pooling statute that allows an operator to propose to the Department of Conservation a unit for a well which, if approved, forces all mineral owners in the unit to pool their interests for the drilling and production of that well. According to the plaintiffs, this statute only authorizes the Department to approve units large enough to cover an area drained by one well. The practice in Lousiana for the Cotton Valley and Haynesville fields is to obtain orders for 640-acre units, and later obtain approval to drill additoinal "alternate unit wells" on those units. The suit contends that this practice is unfair to the owners of minerals and royalties in the unit, and violates state law. The suit seeks certification of a class action on behalf of all owners of mineral rights in Haynesville Zone in Louisiana. It seeks a declaration that the Department has no authority to establish a unit having an area in excess of the area drainable by one well, and that any such unit is "null and void." The suit also seeks unspecified damages against the defendant companies.
An interesting article describing the history of forced pooling in Louisiana and arguing that multiple-well units are illegal may be found at fairdrilling.com.
I have written previously about the proceeding before the Texas Railroad Commission for adoption of field rules for the Carthage (Haynesville Shale) Field. In that proceeding, the applicants sought and obtained field rules establishing a standard proration unit of 640 acres for wells in the field, with "optional" 40-acre units. The examiners who heard the evidence opined that Devon had produced no evidence that a well in the field could drain 640 acres, and they recommended a 320-acre standard unit, but the Commissioners overruled them and agreed to Devon's request for 640-acre units.
It appears that in both Lousiana and Texas the regulators are going along with the fiction advocated by operators that wells in the Haynesville should be developed with 640-acre units, despite the fact that everyone knows the wells will in fact be drilled with 160 or 80-acre spacing. Everyone understands that this fiction is intended to accommodate the desires of the operators to construct larger units in order to (i) have more flexibility in how they space their wells and (ii) hold more acreage with a single well. I have sympathy with the first objective, but not with the second. It is impossible to drill wells with horizontal legs of 5,000 feet or more unless fairly large units are created. Conversely, it is unfair to the mineral owners in a large unit for their leases to be held by production from a single well in the unit where several wells are necessary to fully develop the reservoir under their lands.
