What Petrel Robertson Consulting does

Petrel Robertson Consulting Ltd. (PRCL) is a Calgary-based geoscience and engineering consulting firm established in 1972, providing subsurface expertise to the energy sector. The firm's service portfolio centers on professional consulting across geoscience, engineering, and energy advisory for oil and gas projects, including subsurface analysis, evaluation, and advisory services delivered to energy companies in Canadian and international markets. Its value proposition rests on combining subsurface domain knowledge with broader geoscience and engineering capabilities, served through a vertical go-to-market targeting energy sector clients requiring multidisciplinary technical expertise. The firm's customer segment is exclusively energy companies needing subsurface and geoscience consulting support.

As of June 2, 2026, PRCL was acquired by GLJ Ltd., a Calgary-based global energy consulting firm, and the entity ceased to operate independently. The acquisition combined PRCL's subsurface expertise with GLJ's multidisciplinary technical capabilities to create a broader service offering in geoscience, engineering, and energy consulting. Key personnel Brad Hayes and Kathleen Dorey transitioned to GLJ as Senior Geoscience Advisors, anchoring the subsurface practice within the larger platform. PRCL's headcount sits in the 11-50 range, consistent with a boutique technical consultancy rather than a scaled advisory practice.
