ABOUT COURSE
When you get stuck, your first action must be correct and swift. Otherwise your chances to free up your string will diminish exponentially with every passing minute. This course will be all about prevention rather than cure. It will teach the complete process of detection, diagnostics, and resolution in a methodical way. The student will be working in teams to analyze real field cases and present their solution. The course will address advanced topics in hole problems such as depleted sands, supra and subsalt gouge zones, fractured rocks, salt problems, and HPHT drilling windows. In addition, the student will learn how to perform the math required for diagnosing and resolving these problems. All 25 plus causes of stuck pipe will be addressed, what causes each, how to identify them, what immediate action can be taken. The Course shows the role of each member of the rig team in the chain to facilitate proactive early diagnosis. This course is set a part from other traditional courses by its extensive use of integrated approach of data analysis and clever use of drilling trends and cuttings analysis.
With your data, the course can be customized, and past stuck pipe incidents can be utilized in the course. Our experience indicate that customized courses to address regional hole problems is far more beneficial to the operators.
OBJECTIVE
This course is designed to address preventive measures to prevent the occurrence of stuck pipe or at least minimize its frequency. The full spectrum of monitoring, diagnosis, and resolution will be addressed. The student will leave this course fully mindful of the importance of adhering to best practices in all aspects of the well construction process.
WHO SHOULD ATTEND
Anyone who is connected with well construction from the planning phase to post mortem including drillers, tool pushers, drilling engineers, geologists, crew members, and service personnel.
COURSE MATERIALS
The course will be delivered using a mixture of power point presentation and heavy class participation (almost 70% hands on practical and discussions).
