Welcome to the IGI website

IGI: Integrated Geochemical Interpretation.

Established in 1983, IGI Ltd is a petroleum geochemical consultancy and producer of geochemical software.  Operating worldwide, we offer the following services to the petroleum industry:

  • Consultancy: geochemical interpretation and basin & petroleum systems modelling project work
  • Training Courses: a range of training courses on petroleum geochemistry & basin modelling, and field trips
  • Data and Reports: a suite of geochemical databases/reports for various petroleum-producing regions
  • Software: specialist programs for collating, storing, quality assuring and interpreting geochemical data, built to be applicable across a range of scientific application domains

We are continually innovating, and are exploring diversifying into other areas including decommissioning, and other application domains requiring geochemistry expertise, collaborating with other companies where mutual benefit exists.


The North Sea Transition Authority (NSTA) have announced the 33rd Offshore Licensing Round, with nearly 900 blocks and part-blocks available across the West of Shetland, Northern North Sea, Central North Sea, Southern North Sea and East Irish Sea. Over 35 years, IGI have worked across the whole UKCS to help understand petroleum charge risk through integrated geochemistry and basin modelling. We can provide a range of cost-effective and time-efficient services; from regional studies defining the timing/quantity of hydrocarbon charge to detailed prospect appraisal with PVT prediction. Contact us now to discuss how we can support you.
