A Pennsylvania couple, who entered an oil and gas lease with Range Resources, is accusing the company of failing to stick to a cap on the deductions it took from royalty checks for costs incurred after the gas was out of the ground, according to the Observer-Reporter.

On Sept. 27, Robin and Thomas Pflasterer filed a civil complaint in Washington County Common Pleas Court, claiming Range broke its deal by causing them to lose money when it didn’t drill additional wells.

In addition to a judgment against Range, costs and termination of the lease, the complaint also seeks “an accounting of each monthly royalty payment since March 2011” and “copies of all source documents or electronic databases from which the information was derived,” based on the plaintiffs’ suspicion there could be “further discrepancies” in the royalty calculations.
