ABOUT COURSE
OBJECTIVE
This course will address advanced drilling topics which is essential and timely in today’s drilling technology climate. These topics were carefully selected to add to the skill set of a novice as well as advanced drilling engineer. The course intends to stress the appreciation of the complexity of the management of the drilling process to better integrate with company strategic goals. Key drilling efficiency improvements areas were presented in a way to emphasis real time drilling problems diagnostics, mitigations, prevention, and problem solving. Issues concerning technical limits, advanced wellbore stability analysis, pore pressure and fracture gradient estimation strategies before and during drilling are highly critical topics for anyone involved in the drilling process. These topics shine throughout the fabric of this highly acclaimed and practical course.
WHO SHOULD ATTEND?
Anyone who is connected with well construction from the planning phase to post mortem including drillers, engineers, geologists, geophysicists, and environmental engineers.
