Well Site Geology

Program Objectives


This 5-day course is intended for geologists that either have no previous well site experience or those that have no recent experience in well site geology. Emphasis is placed on providing the well site geologist with a basic understanding of their roles and responsibilities pertaining to the overall drilling operation both in the office and on the drilling rig. Participants will gain knowledge in preparing for a drilling operation, obtaining the best quality data during the drilling operation, providing onsite leadership, coordinating with other disciplines involved in the drilling operation and summarizing results at the end of drilling program.
