With no sign of a ruling by the U.S. Court of Appeals for the 9th Circuit on a lawsuit over Shells U.S. Beaufort Sea exploration plans, the company has decided to call it quits on its planned Beaufort Sea drilling program during the 2008 open water season. The company had hoped to do some top-hole drilling at its Sivulliq prospect on the west side of Camden Bay, as well as conducting some geotechnical boring in the seafloor.
