Chesapeake Energy went to the Texas Supreme Court last week to defend how it deducted post-production costs from royalty checks in a case that is being widely watched by the oil and gas industry and property owners suing the company for millions of dollars. Chesapeake is appealing a San Antonio appeals court ruling from 2014 upholding a state district court decision that awarded the prominent Hyder family of Fort Worth at least $1 million in royalties, interest and attorneys fees.
