DP-Master Manufacturing

What DP-Master Manufacturing does

DP-Master Manufacturing is a Singapore-headquartered, privately held oilfield equipment manufacturer (founded 2005) that produces drill pipes, heavy weight drill pipes, drill collars, and drill string accessories from a single manufacturing plant in Jiangyin, Jiangsu Province, China. The company differentiates through five proprietary premium rotary shouldered connections (DPM-DS, DPM-MT®, DPM-ST®, DPM-HighTorque, and DPM-OPTiMA) offering up to 40% higher torsional strength than standard API connections, supported by in-house processes including tube upsetting, heat treatment, friction welding, cold rolling of thread roots, and internal plastic coating. The product range is qualified to API 5DP, API 7-1, and NS-1 Facility Level 5 specifications, and includes specialized sour service grades (DPM-CY, DPM-SS) and high-strength grades (DPM-140, DPM-150) for deep water, extended reach, HPHT, and H2S environments.

DP-Master sells primarily through an enterprise field sales motion to drilling contractors and oil & gas operators in challenging environments, with documented shipments and partnerships across Norway, Brazil, Kuwait, Saudi Arabia, the UAE, Japan, and Australia. Revenue is generated from hardware sales of drill string products (the dominant stream) and from a Technical Support & Services Group that operates a global licensee network — including Daruma Iron Works in Japan — for authorized precision repairs of proprietary connections. Pricing is project/contract-based and not publicly disclosed, and no revenue figures, funding history, or M&A activity have been publicly reported. Notable named end customers include Statoil (North Sea, 5+ years using DPM-MT®) and KDC (Rig 49 deployment of DPM-ST®57). The company is led by CEO Patrick Murphy, achieved an EcoVadis Bronze Medal in January 2024, and has a headcount of 11-50 employees.
