What Rockflow does
Rockflow Resources Ltd. is a privately held UK-headquartered (Haslemere, Surrey) independent advisory firm serving the global upstream oil and gas industry. Founded in 2012 and operating with 11–50 employees, the company delivers expert subsurface, technical, commercial, and management consulting to E&P companies (from supermajors to small independents and NOCs), government agencies, law firms, and investors across Europe, Africa, the Middle East, the Far East, Central Asia, and North America. Four service pillars structure the offering: Management Advisory (organisational development, commercial negotiation and dispute resolution, energy transition, due diligence and valuation, interim management, business strategy and governance, and digital-age transformation consulting); Expert Services (independent expert witness for arbitration and litigation, expert determination, and unitisation and redetermination); Technical Excellence (technical assurance and peer assist, due diligence, reserves evaluation and audit, subsurface evaluation, integrated project delivery, and specialist support in depth conversion, geomodelling, and petrophysics); and Rockflow Training (specialist depth conversion, Petrel-based depth conversion, and asset management courses).
The delivery model is human-expertise-led rather than software-led: there is no platform, API, or proprietary technology stack, and differentiators rest on the seniority and tenure of the consultant bench and the firm's explicit positioning as conflict-free and independent. The bench includes practice leads with 25+ years of experience and advisors reaching 40 years in the industry, including a former BP VP for Global Projects (Russell Smith) and senior leaders from BP and Shell (Keith Magowan, Mark Manser). Revenue is generated via project-based and day-rate consulting engagements, advisory retainers, and fixed-fee projects, with multi-year contracts common and pricing not publicly disclosed.
The go-to-market is sales-led: direct enterprise engagement with senior-level business development, supported by a content marketing engine (articles, whitepapers such as "The timeless value of Decision Quality in 2025," LinkedIn, YouTube, email newsletters) and industry event participation. Ownership is management-owned with no disclosed institutional investors or parent, and the operating geography is globally distributed despite the single UK office.
