Geography

Approximately 150 miles west of Prudhoe Bay, Alaska, Smith Bay stretches from Dease Inlet, Alaska to Cape Halkett, Alaska. Bordered by barrier islands that separate the shallow, brackish waters from the Beaufort Sea, several slow-moving rivers flow into this region. Along with its adjacent waters, Smith Bay is a shallow-water estuary.

There is a known oil seep at Cape Simpson on the western side of Smith Bay. In 2015 and 2016, Caelus Energy Alaska drilled two exploration wells in the southern part of the bay. In October 2016, the company announced what it called a major oil discovery in the bay and said it would drill a third well in January 2018 and proceed with permitting a pipeline afterwards.
