Petrolog Group

What Petrolog Group does

Petrolog Group is a Houston-based, privately held engineering and offshore services contractor founded in 1983, employing 501-1,000 people. The company provides an integrated suite of eight service lines spanning the full project lifecycle: EPCI (Engineering, Procurement, Construction & Installation), EPCM (Engineering, Procurement & Construction Management), Survey Services, Offshore Marine Support, Subsea Services, Engineering, Asset Integrity & Operations, and Digital & Optimization. Its service portfolio covers site characterization, geophysical survey, multidisciplinary engineering from FEED through detailed design, offshore construction and installation, dive support, vessel operations, subsea intervention and lifecycle maintenance, and integrity management for producing assets.

The company's delivery model emphasizes single-point project accountability, with engineering discipline as the technical spine across both EPCI and EPCM engagement structures. Underlying capabilities include owned or operated marine assets, subsea installation tooling, and engineering-led digital solutions centered on digital twins, data analytics, and performance optimization. HSEQ systems, governance frameworks, and local content development are positioned as differentiators, particularly in West Africa, where the company has operated continuously for over 45 years.

Petrolog serves enterprise clients in offshore oil and gas, subsea infrastructure, marine logistics, onshore industrial infrastructure, energy transition, gas monetization, and brownfield asset operations. It distributes services through direct enterprise sales engagement, supported by a dedicated Client Portal and Employee Portal, across geographic markets including the United States, Nigeria, Angola, Namibia, Latin America, and global deepwater zones. Revenue is generated through negotiated, project-based contracts with pricing not publicly disclosed, and the company appears to be independently operated with no disclosed parent company or institutional investor.
