Anglo-Dutch supermajor Shell said Thursday it has no plans to pursue frontier exploration offshore Alaska and plans to fully divest its shallow-water leases there to a new operator.

The company has applied for unitisation of its 18 leases in state waters in West Harrison Bay in order to pursue a commercial agreement with an alternative operator, a Shell spokesman told Upstream via email.

"Shell has no intention to operate these leases, which were originally purchased in 2012 and are due to expire in 2022," the spokesman said.
