Applied Drillstring Mechanics for Drilling Engineers

Robello Samuel, PhD

INSTRUCTOR: Robello Samuel, PhD
DISCIPLINE: Engineering
COURSE LENGTH: 2 Days (Classroom), 4 half-day sessions (Live Online)
CEUS: 1.6
AVAILABILITY: Public, In-House, & Live Online

SAMPLE TOPICS FROM THE CLASS: “Drillstring Design and Drilling Optimization with Mud Motor Operation” “How Does Well Design, Engineering and Realtime Operation Impact Performance, Efficiency and Optimization?”

WHO SHOULD ATTEND: Drilling engineers, well operations personnel, rig supervisors, drilling supervisors, and pipe manufacturers who would like to gain greater understanding of mud motor design and their applications in drilling.

COURSE DESCRIPTIONThe course provides a comprehensive treatment of drill string design, practices with theoretical underpinnings. Various operational loads and limits discussed will provide more comprehensive view of the drillstring mechanics. It also covers advanced drilling engineering, enabling participants to understand the drillstring integrity under various operating load conditions. The class also covers the BHA design concepts, drillahead and drillstring dynamics. Participants will be provided on the realtime time monitoring and optimization and predictive conditions when the well is drilled. Upon completion of this course, participants will not only have deeper knowledge of the basic engineering principles used in the drillstring design but also have confidence to use them efficiently for consulting as well as solving complex problems effectively.
