Career & background
Borisuitsawat took his current group leadership role in December 2025 after overseeing domestic production assets. His earlier work included drilling assignments in Malaysia and Algeria, followed by responsibilities in safety, engineering and organisational transformation. He studied petroleum engineering at Chulalongkorn University and management and strategy at Mahidol University. This background combines technical operations with experience of leading change across different business functions.
Areas of contribution
A documented example of his wider remit is PTTEP’s Ocean for Life initiative at Koh Tao. In April 2026, he co-presided over the launch of an underwater sculpture and artificial reef installation with Thailand’s Department of Marine and Coastal Resources. The programme brought together universities, tourism organisations and local participants. Its stated aims include supporting marine habitats, tourism and community livelihoods; the company described continued monitoring as part of assessing its effects.
Leadership focus
The combination of technical leadership and cross-sector collaboration is a useful lens on his work. PTTEP’s July 2025 operational excellence event, which he opened while leading domestic production assets, connected business strategy with continuing improvement. His current role places technology and carbon solutions alongside sustainable growth. Together, these responsibilities show the importance of linking engineering decisions, organisational capability and environmental considerations within an energy business.
