Cody, WY – The Wyoming Oil and Gas Conservation Commission has ruled against a Park County landowner who tried to invoke Wyoming's new split estate law. The landowner sought to force an energy company to pay a higher bond for drilling on his land. The ruling yesterday rejected arguments by Heart Mountain landowner Jim Dager that Windsor Energy should post a $416,000 surety bond. He argued that was to cover the loss of value of nearly a thousand acres surrounding planned gas drilling operations.
