What is APT (apt-int.com) and what services does it provide?

Updated

APT (apt-int.com) is an analytical and consulting firm serving the petroleum industry, specializing in organic geochemistry, petroleum systems modelling, and biostratigraphy. It is relevant to you if you need laboratory analyses, basin modelling, or interpretation services for whole rock and fluid systems — particularly if you want geochemical data integrated into calibrated basin models rather than delivered as raw numbers alone.

What APT does

According to the site, APT provides "high quality analytical and consulting services in organic geochemistry, petroleum systems and biostratigraphy." The stated goal is to help clients "obtain an enhanced understanding of your whole rock and fluids system and unlock the potential in your basin through careful integration of data into calibrated basin models."

Two things distinguish the offering:

  • Integration over isolated analysis. The emphasis is on feeding geochemical data into calibrated basin models, not just reporting measurements.
  • In-house laboratories. APT states it offers geochemistry services "from our specialist laboratories," meaning analysis and interpretation sit under one roof.

Core service areas

Area What it covers
Organic geochemistry Laboratory analysis of rocks and fluids
Petroleum systems modelling Basin models calibrated with geochemical data
Biostratigraphy Age and correlation work for petroleum exploration
Consulting and interpretation Bespoke studies integrating data into models

The site organizes services two ways: an "Explore all services" entry point and a "Services by sample type" view, which is useful if you already know what material you need analyzed.

Project scope and quality control

APT describes "a large number of bespoke geochemistry and petroleum systems modelling studies covering key active areas of the globe." An interactive map on the site lets you view where these projects are located — worth checking if you want evidence of experience in your region.

On data quality, the site states that "all of our projects involve vigorous QC of available data to ensure high quality and consistency." This matters in geochemistry, where results are only as reliable as the calibration and screening behind them. One of APT's own news items asks, "Do you know how good your geochemical data is?" — a signal that data validation is part of how they position their work.

Beyond services: training and resources

APT also publishes material that may be useful even if you are not commissioning a study:

  • Training courses — the site announced "Geochemistry Training Courses Now Live!"
  • Technical notes and downloads — including a "Production Allocation Using Geochemistry" article and an "APT SI Toolkit for Drainage Diagnostics" PDF.
  • Conference activity — APT lists appearances at events such as the Unconventional Resources Technology Conference (URTeC) 2026 and a 2025 conference schedule.
  • Company background — the site notes APT "reaches a new milestone with 25 years of continuous operations."

How to decide if APT fits your needs

Consider APT if you need:

  • Geochemical analysis paired with interpretation, not just lab output.
  • Petroleum systems models calibrated against measured data.
  • Biostratigraphy alongside geochemistry in one study.
  • A provider with documented project experience across multiple global basins.

The site does not publish pricing, so cost and contracting terms would need to be raised directly. The most practical next steps are to browse the services-by-sample-type page for your material, check the interactive map for regional experience, and review the downloadable technical resources to gauge whether their methods match your problem.
