What Bayphase does
Bayphase Limited is an independent upstream oil and gas consultancy headquartered in Camberley, Surrey, United Kingdom, established in 1986 and operating globally across more than 45 countries. The firm delivers five integrated core services for oil and gas exploration and development projects: Resource Auditing and Valuation, Cost Auditing and Estimation, Field Development Planning, Reservoir Modelling, and Strategic Planning. It also operates a wholly-owned subsidiary, Bayphase Data, which provides subsurface data management and proprietary country-level strategic reports.
The firm's analytical platform combines licences to industry-standard software (Schlumberger Petrel, Eclipse, INTERSECT, Kingdom Suite, Powerlog, Terrascience, Harmony, Prosper, Ecrin, Crystal Ball) with its own proprietary cost estimating tool, NETCO$TER, which is built on decades of internal cost benchmarking data. Work is performed by a team of subsurface and surface technical specialists and economists, each discipline led by an experienced practitioner with prior oil company experience; the team has executed over 200 projects in the last five years. Reports are delivered in accordance with PRMS, SEC, London Stock Exchange, AIM, Johannesburg Stock Exchange, AACE International, API, ASTM, and SPE standards.
Bayphase generates revenue through professional services fees on a project-by-project basis, typically negotiated by scope and complexity. The go-to-market is sales-led and direct, targeting NOCs, IOCs, host governments, and project finance banks. The firm is privately held by its named directors (G Eyre, P Eyre, I Djokic), holds BS EN ISO 9001:2008 certification, and operates with no disclosed external institutional ownership or parent company.

- DeGolyer & MacNaughton: Global independent petroleum consulting firm offering reservoir engineering, reserves evaluation, geological and geophysical studies — a direct competitor for Bayphase's integrated subsurface and reserves certification work for major operators and lenders.
- Sproule (a Levenergy company): Independent energy consulting and certification firm providing reserves evaluation, geoscience and reservoir engineering services — directly overlaps Bayphase's reserves, geological and reservoir modelling offerings for upstream clients.
- Netherland, Sewell & Associates: Long-established independent petroleum engineering firm specialising in reserves estimation and resource evaluation for SEC, PRMS and international stock exchange compliance — directly overlaps Bayphase's Competent Person Reports and reserves auditing services.
