G1: Introduction to


2024 Programme

3 Days | £1500+VAT per attendee

Course Aims

To provide an introduction to Petroleum Geology and practical wellsite geological procedures for engineers and other staff without formal geological training.

Target Audience​

Drilling Engineers, LWD Engineers, Directional Drillers, Drilling Fluids Engineers, Support Staff, all non-geological personnel.

Delegates Will Learn:

  • How to recognise the physical and chemical properties of the major sedimentary rocks

  • How to examine hand specimens and drill cuttings

  • How to understand subsurface structures and basic reservoir geology

  • How to understand the effect of geology on key drilling practice

  • How to interpret lithology and geological features from LWD and wireline logs.
