Norwegian state-oil company Equinor ASA said June 5 it was shutting in production on its Titan platform in the U.S. Gulf of Mexico (GoM) while other producers evacuated workers ahead of Tropical Storm Cristobal.

Cristobal had weakened to a tropical depression while over land in Mexico but returned to tropical storm strength as it approached reentry into the Gulf around midday June 5.

Cristobal is forecast to strike the central Louisiana coast the evening of June 7 after passing through the heart of U.S. offshore oil production areas over the weekend, according the U.S. National Hurricane Center.

Equinor will evacuate remaining workers later June 5, a spokesman said.

U.S. producer Murphy Oil said it was evacuating all workers from the GoM, but declined to say whether production was affected.

Royal Dutch Shell Plc said June 5 there has been no impact to offshore oil production from Cristobal, but it expects a minimal impact to drilling.

Shell is evacuating non-essential workers in the GoM as Cristobal begins moving north to reach the Louisiana coast.

Occidental Petroleum Corp. also has evacuated non-essential workers from some of its central GoM facilities.

BP began shutting in production June 3 as it was pulling workers from the GoM.

The U.S. Energy Information Administration expects the GoM to account for 15% of total U.S. crude oil production in 2020.
