Stuck Pipe Prevention Training

The Topics covered during the 2 day Stuck Pipe Prevention Training include:

Causes of stuck pipe

• Differential sticking
• Mechanical sticking

Prevention of stuck pipe

• Differential sticking
• Inadequate hole cleaning
• Formation instability
• Key seating
• Bottom hole assembly changes
• Plastic salts

Freeing stuck pipe

• Soluble formations
• Key seating
• When to give up attempts to free the pipe

Jars and accelerators

• Forces required to fire jars
• Handling of small drilling / fishing jars
• Accelerator description
• Jar and accelerator position

The Structure of the 2 day Stuck Pipe Prevention Training will include:

Day One

• What is stuck pipe, what is the cost of stuck pipe and when is it most likely to happen?
• An introduction to rocks and stresses including mechanical instability and planning for wellborn stability, avoiding high risk situations, tripping and reaming practices and the factors in hole cleaning and how they interact
• Sticking mechanisms and how to address them including hole cleaning, formations, fractured rock and junk and cement
• Differential Sticking, its causes and minimising risk
• Well Geometry, doglegs and ledges, mobile formations and collapsed casing

Day Two

• Mud properties and their effect on stuck pipe
• Drill pipe, jars and accelerators
• How are we sticking, where are we stuck and what should we do?
• Differential sticking
• Bore hole geometry
• Simulator session – Working through stuck pipe challenges as a team
• Exam and Results

On successful completion of the training, participants will be able to identify, reduce and free stuck pipe in rotary, directional, horizontal, mud, top drive, offshore or under-balanced drilling operations.

You will receive a certificate of completion. This is a technical course created by Harness Energy and is not aligned with national accreditation or qualifications.
