PepsiCo to Gazprom Facing Sales Threat in Ukraine Standoff

Russia’s military intervention in Ukraine threatens to derail energy exploration in a region that holds a quarter of the world’s natural gas reserves, weigh on currencies and force companies to work to contain the damage.

Chevron Corp. heightened security for employees involved in searching Ukraine’s shale fields for gas. The eastern European nation’s ambitions to become a shale-gas exporter by 2020 could be dashed as the conflict escalates, while Russia faces the prospect of sanctions that may curb gas sales that account for 20 percent of its export revenue.
