G2: Operations & Wellsite Geologist


2024 Programme

4 Days | £2250+VAT per attendee

Course Aims

To provide an overview of the role of Operations and Wellsite Geologists in Well Planning and Drilling Surveillance phases. To provide practical instruction in wellsite geological techniques and geosteering co-ordination.

Target Audience​

Wellsite Geologists, Operations Geologists, Reservoir and Development Geologists, Drilling Engineers, Mudloggers, LWD Engineers, Directional Drillers, Support Staff.

Delegates Will Learn:

  • How to describe & Evaluate drill cuttings

  • How to produce a Formation Pressure Profile to include estimated pore pressure and fracture gradient data

  • How to determine Lithology and Reservoir information from well logs

  • How to use Mudlogging and MWD data to perform real-time geosteering co-ordination.
