The 2009 Montara oil spill, 250 km off Australia's northwestern coast led to "Thousands of barrels of oil gushed into the ocean over a 10-week period following a blowout at PTTEP Australasia's West Atlas rig in the Timor Sea".

The 2013 Rayong oil spill started on the night of 28 July 2013.

The crude oil spill had occurred 20 km off Thailand's mainland, "when a floating hose transferring oil from a tanker to a PTT refinery pipeline broke sending 50,000 litres of oil spewing into the coastal waters".

In an action by the US Department of Justice (DOJ) against aircraft engine-maker Rolls-Royce, the DOJ claimed that Rolls Royce had paid more than US$11 million in commissions to win a deal with Thai Airways, aware that some of the funds would be used to bribe officials at PTT and its subsidiary, PTT Exploration and Production (PTTEP). The payments were made from 2003-2013 and related to contracts for equipment and after-market products and services. Admitting its guilt, Rolls-Royce paid US$170 million to settle the case. PTT vowed to investigate. Subsequently, PTT Chairman and CEO Tevin Vongvanich said that the company was unable to find anyone who "allegedly took bribes".
