Petroleum Experts (Petex)

What Petroleum Experts (Petex) does

Petroleum Experts (Petex), operating through PE Limited, is a UK-based, founder-controlled software company that develops and licenses integrated petroleum engineering and structural geology software to the global upstream oil and gas industry. Founded in 1990 in Edinburgh by Hamid Guedroudj, the company has grown to 101-250 employees serving 450+ clients across 30+ years, including all major super-majors and NOCs such as BP, Shell, ExxonMobil, Chevron, TotalEnergies, Eni, Equinor, and ADNOC. The company maintains offices in the UK (Guildford as the new 2025 headquarters, plus Edinburgh) and the US (Houston, Lafayette), and distributes through 11+ country representatives and service partners covering the Middle East, Asia, Africa, China, and Australia.

Petex's product portfolio is organized into three divisions: PE Engineering (IPM Suite — RESOLVE, GAP, GAP TRANSIENT, PROSPER, MBAL, REVEAL, PVTp, and OpenServer for integrated production modeling, well completions, material balance, and reservoir studies); PE Geology (MOVE Suite — 2D/3D kinematic, geomechanical, fracture, stress, and fault modeling with connectors to Schlumberger Petrel, Halliburton OpenWorks, and GST); and PE Digital (DOF Suite — a vendor-neutral digital twin and real-time field surveillance platform). The technology stack is built on proprietary physics-based solvers, equations-based network models, non-linear optimization, and an OpenServer API for automation and third-party integration.

The business model combines perpetual and subscription software licensing with high-touch technical services (DOF implementation, geological modeling, technical workshops ranging from days to months) and instructor-led training courses delivered worldwide. The company is privately held, profitable, and self-funded, with no external capital, parent company, or public listing, and the CEO remains the founder.

Core offering

Petroleum Experts (Petex) develops and licenses proprietary petroleum engineering and structural geology software, organized into three suites: the IPM Suite (integrated production modelling), the MOVE Suite (structural geology and geomechanics), and the DOF Suite (digital oil field / digital twin). The company also delivers complementary technical solutions consulting, instructor-led training, and ongoing engineering support to oil and gas operators, consultancies, and universities worldwide.

Product overview

Petroleum Experts (Petex) offers a comprehensive suite of engineering and geology software organized into three main product divisions: PE Engineering (IPM Suite), PE Geology (MOVE Suite), and PE Digital (DOF Suite). The IPM Suite is a modular integrated production management system comprising RESOLVE (integration platform with economics and global optimization), GAP (production/injection network modelling), GAP TRANSIENT (transient multiphase flow), PROSPER (well completions and performance), MBAL (material balance and forecasting), REVEAL (reservoir studies and geomechanics), PVTp (fluid characterisation), and OpenServer (API/automation). The MOVE Suite provides structural geology software including MOVE core application, 2D/3D Kinematic Modelling, Geomechanical Modelling, Fracture Modelling, Stress Analysis, Fault Analysis, and Fault Response Modelling. The DOF Suite delivers real-time field management through IVM (Integrated Visualisation and Management), IFM (Integrated Field Model), and Model Catalogue. These products can be used independently or assembled within an integrated system, with optional training courses and technical solutions services.

Broad incumbents

• Schlumberger (SLB): Schlumberger is the largest oilfield services and digital technology provider, with its Petrel subsurface platform and DELFI E&P environment competing directly with Petex's IPM and MOVE suites. Comparable as a vendor of integrated reservoir-to-production software to the same IOC customer base, though far broader in scope and bundled with services.
• Halliburton Landmark: Halliburton's Landmark division offers DecisionSpace and OpenWorks platforms for subsurface modelling, reservoir engineering, and production operations. Directly comparable to Petex's IPM and MOVE in target workflows, though Landmark is bundled within Halliburton's full oilfield services portfolio.
• Emerson (Paradigm / Roxar): Emerson's Paradigm and Roxar suites provide geological modelling, reservoir characterisation, and production software directly overlapping Petex's MOVE and IPM offerings. Comparable in workflows and customer base, but operates as part of Emerson's broader automation and software portfolio.
• Aspen Technology: AspenTech offers industrial AI and process optimisation software including asset performance management and digital twin solutions for process industries. Comparable to Petex's DOF digital oilfield capability at the digital twin and optimisation layer, though AspenTech serves a much broader industrial base.

Direct peers

• Computer Modelling Group (CMG): CMG is a specialised reservoir simulation software provider offering CMG STARS, IMEX, and GEM for flow in porous media, alongside production engineering tools. Closely comparable to Petex's MBAL and reservoir engineering modules for E&P operators and consultancies.
• Kongsberg Digital: Kongsberg Digital delivers digital twin and asset performance software for the energy sector, including the Kognitwin platform for oil and gas field management. Directly comparable to Petex's DOF Suite in delivering real-time surveillance, optimisation, and digital oilfield capabilities to operators.
• Ikon Science: Ikon Science provides RokDoc and other geomechanics, rock physics, and seismic-driven reservoir characterisation software. Comparable to Petex's MOVE and REVEAL modules for subsurface and geomechanical workflows serving the same geoscience and reservoir engineering user base.

Emerging players

• Rokenso (formerly RokDoc operator): Emerging petroleum engineering software vendor offering production optimisation and digital oilfield tools to operators and consultancies. Overlaps with Petex's IPM/DOF value proposition for production allocation and surveillance, though at a smaller scale and narrower footprint.
• Cegal: Cegal is a specialist energy software and consulting provider offering digital oilfield, geoscience, and data management solutions. Comparable to Petex in serving energy operators with production and subsurface software, though smaller in scale and primarily Nordic-focused.

Others

• TGS: TGS provides subsurface multi-client data, imaging, and reservoir intelligence to the E&P industry. Adjacent to Petex as an upstream-focused data and analytics provider whose offerings complement, rather than directly compete with, Petex's modelling and optimisation software.
