What Applied Petroleum Technology does

Applied Petroleum Technology AS (APT) is a privately held Norwegian petroleum geochemistry and basin modelling consultancy founded in March 2000 by four industry veterans including Kjell Urdal and Per Erling, both still active in the business. Headquartered in Oslo with regional offices in Conwy (UK, est. 2008), Calgary (Canada, est. 2013), and Houston (USA, est. 2021), APT delivers specialist analytical and consulting services to oil and gas exploration and production operators worldwide, covering NW Europe, North America, the Middle East, Africa, and through a joint venture with MGPalaeo, Australia and Southeast Asia. The company is founder-controlled, has never raised external capital, and celebrated 25 years of continuous operations in 2025.

APT's service portfolio centres on laboratory geochemistry (GC-MS, GC-MS/MS, stable isotope analysis via IRMS, Rock-Eval pyrolysis, vitrinite reflectance, SARA fractionation, vitrinite reflectance, and sample preparation), petroleum systems modelling (1D and 3D basin modelling), and interpretation services producing single-well, multi-well, regional, and thematic study reports. The company has run NIGOGA analytical standards for over 22 years to ensure precision and accuracy. Proprietary software products include Girasol (wellsite gas interpretation for pay-zone identification and GOR prediction) and APT Allomon (production allocation via geochemical fingerprinting, targeting sub-5% allocation error in conventional reservoirs). APT also operates the proprietary APvT PVT database and a custom Laboratory Information Management System.

APT monetises through fee-for-service laboratory analysis, professional consulting engagements, multi-client regional studies sold to multiple subscribers, software licensing, and training delivered in-person and via the SAGA Wisdom online platform under a quote-based, project-by-project pricing model with multi-year contract cadence. The company employs a small global team dominated by PhD-level geochemists with prior experience at majors and service giants (BP, Statoil/Equinor, Chevron, ConocoPhillips, Schlumberger, Maersk). Recent strategic emphasis includes the New Energy and Innovation function supporting energy transition and low-carbon technology work, and active conference participation (APGCE, IMAGE, SAGA events) for thought leadership and lead generation.

Core offering

Applied Petroleum Technology (APT) delivers laboratory-based petroleum geochemistry analytical services, petroleum systems and basin modeling consulting, proprietary software tools (Girasol, APT Allomon), and multiclient regional studies for oil and gas exploration and production operators. The company operates specialist laboratories providing GC-MS, isotope, Rock-Eval, and vitrinite reflectance analyses, combined with expert interpretation and report writing for individual wells and regional studies.

Product overview

APT provides a comprehensive suite of petroleum geochemistry services as a unified offering rather than a modular platform. The portfolio centers on petroleum geochemistry analytical and consulting services, supported by petroleum systems modelling capabilities (1D and 3D basin modelling). Key software products include Girasol (wellsite gas interpretation) and APT Allomon (production allocation and monitoring). Additional offerings comprise the APvT Database for PVT data, multiclient studies with searchable map access, training services (in-person and via SAGA Wisdom platform), and comprehensive analytical services covering GC/GC-MS/GC-MS/MS, stable isotope analysis, TOC/pyrolysis, vitrinite reflectance, and sample preparation. Services are delivered through specialist laboratories with extensive quality control processes.

Direct peers

• Stratum Reservoir (formerly GeoMark Research, now part of Tetra Tech): Stratum Reservoir / GeoMark provides petroleum geochemistry, PVT analysis, and production allocation services directly comparable to APT's core offerings. Notably, several APT senior staff (e.g., Craig Barrie, Scott Granger) came from GeoMark, evidencing near-identical service portfolios and customer overlap.
• Chemostrat: Chemostrat delivers inorganic and organic geochemical stratigraphy services to E&P operators worldwide, directly overlapping APT's source rock evaluation, reservoir characterisation and wellsite analytical services for similar oil & gas clients.
• IGI Ltd (Integrated Geochemical Interpretation): IGI provides petroleum geochemistry consulting, PVT interpretation and basin analysis to E&P operators. It is one of the closest niche competitors to APT in source rock and fluids geochemistry interpretation.
• Petrostrat: Petrostrat provides biostratigraphy, geochemistry and sedimentology services to oil & gas operators, including palynology and integrated stratigraphic studies that directly overlap with APT's UK biostratigraphy and geochemistry services.

Broad incumbents

• Core Laboratories: Core Labs is a large, integrated oilfield services company offering reservoir fluid (PVT) analysis, geochemistry and production allocation as part of a much wider portfolio. It competes with APT for PVT and reservoir characterisation work with major E&P operators.
• SLB (Schlumberger): SLB is the largest oilfield services company globally, with geoscience, geochemistry and basin modelling capabilities (previously via Schlumberger/Gushor). Several APT senior hires previously worked at Schlumberger, evidencing direct technical and customer overlap.
• Halliburton: Halliburton offers integrated geoscience, formation evaluation and reservoir services that overlap with APT's geochemistry and basin modelling work, especially when bundled with drilling and production contracts for major operators.
• Baker Hughes: Baker Hughes provides subsurface evaluation, geochemistry and reservoir consulting within its broader oilfield services portfolio, competing with APT for integrated E&P study work with international operators.
• Robertson (CGG GeoConsulting): CGG's GeoConsulting arm (including Robertson) provides multi-client and bespoke geoscience, basin analysis and petroleum systems studies for E&P clients — directly comparable to APT's multi-client regional study and basin modelling offerings.

Emerging players

• TGS: TGS provides subsurface data, multi-client studies and analytics to the E&P industry, with growing overlap into basin and petroleum systems analytics that compete with APT's multi-client study offerings.
