Tevin Vongvanich, the PTTEP chief executive, said at Asia OTC 2014 in Kuala Lumpur that his company's  ambition is to grow output by about 8% annually by 2020 at which time output will total about 600,000 barrels per day of oil equivalent.

Domestic production will be the bedrock, representing stable levels of about 250 boe per day, but the company's international assets will deliver the remainder which is a substantial increase on the current overseas harvest.
