The company plans to drill 20 locations in the G4/50 license located in the Greater Bualuang area of the Gulf of Thailand and only 18 of 20 have received EIA approval till date.

The approval is subject to the company updating its oil spill response modeling to account for the removal of two potential drilling locations and communicating the removal of the two locations to local stakeholders.

Salamander will commence exploration drilling at 18 locations by the end of this year.

Salamander chief executive James Menzies said: "We have long been excited about the potential of the G4/50 licence.

"Now that we have the EIA’s in hand we look forward to a low-cost, but high-impact, exploration drilling programme over the next twelve months."

Asia-focused independent exploration and production firm Salamander has several licences spread across Indonesia and Thailand.
