About Course

The course provides a comprehensive understanding of three stuck pipe mechanisms, causes leading to each mechanism, and recognition of warning signs.


Skills Gained

On completion of this course you will be able to fully understand how to:

  • Identify the three sticking mechanisms and the causes
  • Recognize the sticking causes at an early stage and what preventive actions to take before full sticking develops
  • Understand the fundamentals of hole cleaning
  • Discover techniques on stuck pipe prevention
  • Learn to “listen to the well”
  • Perform trend analysis of drilling parameters
  • Stratigraphic column with identification of potential problem formations
  • Review case histories with in-depth analysis.
  • Understand drilling jars, pump open force, and jarring load calculations
  • Appreciate the team approach and the need for good communication

Identify the sticking mechanism and what “First Actions” to take to free a stuck pipe
