U.S. Extended Continental Shelf

U.S. 200-nautical-mile boundary line

Hydrocarbon leasing activities commenced on the U.S. extended continental shelf shortly after the U.S.–Mexico ECS boundary delimitation treaty entered into force. Since August 2001, oil companies have spent more than $47 million to purchase leases located on the western gap ECS. Of the approximately 320 lease blocks located in whole or in part on the western gap, 65 (approximately 20 percent) are currently under active leases held by nine U.S. and foreign oil exploration companies.
