OPS-OES has served the industry since 2010, from a single land rig calibration to full MODU inspection programs.
OPS Oilfield Equipment and Services LTD (OPS-OES), formerly Oilfield Professional Services Ltd. (established in 2007), has been serving Thailand's oil, gas, and energy sectors since 2010. We provide drilling rig inspections, equipment, parts, maintenance, and repair services, plus a complete range of well construction equipment supporting wells from initial drilling to plugging and abandonment.
With four strategic bases in Thailand, one in Myanmar, and a network of global partners, we support projects worldwide — including PTTEP, COSL, Sapura, Borr Drilling, Seadrill, and Sinopec, with 423+ documented inspections since 2010.
OPS-OES is led by a management team with a combined multi-decade track record across drilling, rig inspection, and oilfield operations in Thailand and Myanmar — the same team that has overseen 423+ inspections and built OPS-OES's certifying-authority relationships with PTTEP and IADC. Full individual leadership profiles are in progress and will be added here shortly.
