PETROG includes patent protected technology.



We offer training for PETROG and PetrogLite.

Please contact us if you would like more information.


We have training available in how to use and get the best out of your software. The training can be arranged to be at your site, in the UK or on-line.

Training courses can be given to individuals or on a group basis and can be tailored to suit new or existing users.

For who ?

PetrogLite and PETROG are rich in features, and so user training can help you get the best out of the tool, to make your workflow more efficient and allowing you to concentrate on producing quality data.

Even if you are already using PetrogLite and PETROG, consider a refresher course to ensure you are making the best use of your software.

We have set courses, or the course can be tailored to meet your requirements, novice or expert.

How many ?

Training can be tailored to suit individuals or groups.

Where ?

Training can be arranged at a location of your choosing. It can be at your site or here in the UK; or we also offer RILT (Remote Instructor-Led Training) courses.

PETROG Training Courses:

Overall Goals:

  1. Optimising petrographic data collection, using PETROG based on sound statistical practice.
  2. Maximising benefit from data analysis, using statistical methods in PETROG and using PETROG to prepare data for analysis in other software.

Delivery Options and Schedules

Training can be offered as either remote instructor-led courses or as on-site courses. If remote, the modules can be organised into short sessions, e.g. of one hour each, spaced as requested and to fit in with working routines. For example, it may be most convenient to have one session each day or one session each week. In any case, there would be practices and exercises set between modules. If training is undertaken on-site, the practical work can be incorporated within each module, in which case the set of petrographer–aimed modules (2 to 6) should be completed in 3 days.

Module 1 is primarily aimed at IT specialists e.g. installers, database administrators.  This module represents one half day of contact time, and can be offered stand-alone or in addition to the main modules.
