Oil giant Chevron Corp is considering a sale of its roughly US$500 million stake in its Thailand gas field.
As Chevron moves to sell, the Thai government is moving to negotiate a better return from the very same petroleum concessions.
The US oil company has held preliminary talks about selling the stake to PTTEP which owns 80% of the gas field and is the operator of the gas field.
PTT Exploration & Production (PTTEP) is the country's largest publicly listed oil and gas explorer.
