Course Information
This course has been written for Operators, Drilling Contractors and Service personnel who require an in-depth detailed understanding of the causes of stuck pipe (which includes drill pipe, BHA’s, casing, liners and logging tools) and how sticking can be prevented.
As compared with the standard Stuck Pipe Prevention Course, we spend more time studying downhole tectonic / rock mechanics forces (including wellbore stability / instability with respect to mud weight, mud chemistry, hole angle and azimuth), the importance of optimised drilling fluids design, BHA design, optimised well design, optimised drilling practices, jar placement, jar calculations & jar firing, why problems exacerbate on high angle / ERD / horizontal wells and the importance of effective teamwork & communication.
For the “practical session” of the course, we work through a number of advanced-level stuck pipe case histories (which were all preventable) to cement the delegates learning & understanding.
Duration: 3 Days
Skill Level: Advanced
