Stuck Pipe Prevention

Stuck Pipe Prevention Measures 1

Mechanisms for Stuck Pipe – Causes, Occurrence, and Prevention

• Introduction to Stuck Pipe

• Solids Pack Off
  • Case History, Group Exercise and Discussion

• Differential Pressure
  • Case History, Group Exercise and Discussion

• Wellbore Geometry
  • Case History, Group Exercises and Discussion

Participants will receive a quick review of stuck pipe problems and their huge impact on the economic and feasibility of drilling projects. The day will move forward with a detailed analysis of stuck pipe mechanisms illustrated with group discussion of case histories and class exercises.

Stuck Pipe Prevention Measures 2

• Stuck Pipe Diagnosis – First Actions
  • Group Exercise and Discussion

• Hole Cleaning, Low & High Angle
  • Group Exercises and Discussion

• Principles of Wellbore Stability
  • Case History, Group Exercises and Discussion

Participants will learn the identification of the stuck pipe mechanisms and the recommended first actions using the tools available, illustrated with group exercises.

Both Hole Cleaning Practices for low and high angle wells, and wellbore stability problems, will be complemented with group exercises, discussions and case history.

Stuck Pipe Prevention Measures 3

Tools and Procedures;

• Hole Conditions Monitoring: Rig Site Warning Analysis
  • Case History, Group Exercise and Discussion

• Well Engineering and Offset Well Analysis
  • Group Exercise and Discussion

• Recommended Practices for Stuck Pipe Avoidance

Day three will be focus in the interpretation of Rig Site Warning Signs through real time monitoring of drilling parameters. Then a discussion of Offset Well Analysis as a tool for prevention of stuck pipe events.  The day will end with a detailed discussion of the operational practices for stuck pipe avoidance.

Stuck Pipe Prevention Measures 4

• Connection Practices – ECD Management – Tripping Practices

• Reaming and Back Reaming Procedures
  • Case History, Group Exercise and Discussion

• Jar Placement and Operation

• String Separation Options: Cutting and Back-Off

Participants will learn additional practices for making connections, tripping procedures, reaming and back reaming operations. The day will continue with selection, installation, and operation of the Drilling Jar, as well as string separation options once the drill pipe becomes stuck.
