XTO Energy Inc. has been assessed a $1.33 million federal penalty for "knowing or willful" failure to allow an audit in North Dakota concerning multiple lease, or communitization, agreements. The Department of Interior's Office of Natural Resources Revenue (ONRR) said at issue was information related to federal leases that were combined because they draw from the same oil or natural gas reservoir. A request was made in February 2013 that the ExxonMobil Corp. affiliate comply with a data request by April 1, 2013. Despite "numerous" requests, the company did not comply until February 2014, "preventing timely completion of North Dakota's audit," ONRR said. The agency is responsible for collecting/disbursing revenues from energy production that occurs on federal and American Indian lands.
