Stuck Pipe And Hole Cleaning
Course Objectives
A practical treatment of the causes of stuck pipe concentrating on (poor) hole cleaning as a primary cause. Covers drill string design, wellbore stability and lost circulation. Detailed discussion on the key elements of stuck pipe together with drilling fluids, hole cleaning and cuttings behavior.
Prerequisites
Participants should have a fundamental understanding of drill strings and some exposure to well site drilling operations, as well as basic math skills.
