Subash Rajan

Lead Trainer · Senior Drilling & P&A Supervisor

Subash Rajan is Sura Energy Drilling's Lead Trainer and a Senior Drilling and Plug & Abandonment (P&A) Supervisor. He brings 28 years of multinational onshore and offshore experience — most of them with Schlumberger (1996–2020), followed by supervisory roles for PETRONAS, Halliburton and SLB — and has delivered more than 100 courses and workshops.

He began his oilfield career in 1994 through the PETRONAS Apprentice Program at ILPP Batu Rakit (now INSTEP), later earning an HND in Mechatronics from Liverpool John Moores University, a Bachelor of Engineering in Mechanical and Offshore Engineering from Robert Gordon University, Aberdeen, and a specialised certification in Plug and Abandonment from the University of Aberdeen.

His field career spans MWD/LWD and directional drilling services, real-time drilling support for up to 20 rigs across South East Asia and Australia, wellsite leadership for Saudi Aramco and QGC (Australia), and offshore drilling and P&A supervision for PETRONAS in Sarawak and Peninsular Malaysia — including HPHT, PMCD, anti-collision and H₂S well environments.

As a trainer he is engaged by oil and gas companies and academies to deliver stuck pipe prevention, jar workshops, wellbore problems, hole cleaning and HPHT courses to rig crews on site and via virtual platforms — for Velesto Energy, Sapura Energy, PETRONAS, PETROS Sarawak, PTTEP Malaysia and international drilling contractors.

Today he coaches the next generation at Velesto Academy at INSTEP — the same institution where his own career began — and spoke to school leavers about energy-sector careers at the launch of TVET Negara 2026 2.0 in Putrajaya.
