In 2018 the U.S. state of Iowa listed PTT Exploration as an Iran restricted company rendering PTT Exploration ineligible for investment and/or state contracting.
"Thailand’s PTT Exploration and Production Public Company Limited (PTTEP) has handed over the result of its studies on a number of Iranian oil and gas fields to the National Iranian Oil Company (NIOC). The studies included development projects of Changouleh, Balal and Dalamperi oilfields in Iran. NIOC will weigh studies of the Thai company to decide whether to award the projects to it. NIOC has signed memoranda of understanding (MoUs) with several other oil majors to study the same fields." (August 29, 2017).
Iran has signed a basic agreement with Thailand’s PTT Exploration and Production Public Company Limited (PTTEP) to study its Changuleh oil field which appears to be one of the country’s emerging top oil project prizes. Based on the agreement that the PTTEP signed with the National Iranian Oil Company (NIOC), it would have to study Changuleh – as well as Balal and Dalamperi oil fields - within six months. The Ministry would then evaluate the Thai company’s findings and decide on whether to award the project’s development to the company. Gholam-Reza Manouchehri, the NIOC deputy for engineering and development affairs, told reporters after signing the agreement with the PTTEP that several other international companies had also won agreements to study the three fields. (Press TV, "Thailand's PTTEP to study Iran's Changuleh" 12/6/2016).
PTT Exploration and Production engaged in exploration and development of Iran's Saveh block natural gas field, signing a 25-year contract in 2005 for a 100% stake in the Saveh block (GAO Report 2010, "Firms Reported in Open Sources as Having Commercial Activity in Iran’s Oil, Gas, and Petrochemical Sectors").
