STUCK PIPE PREVENTION AND FISHING OPERATIONS
Course Description
Why Choose this Training Course?
This Stuck Pipe Prevention & Fishing
Operations training course provides a comprehensive coverage in the industry
for understanding and preventing the underlying causes of Stuck Pipe, Wellbore
Instability, Loss Circulation, and other sources of Non-Productive Time (NPT)
in drilling operations. The course also focuses on correct responses by
individuals and teams, early warning signs, and minimizing the impact to
drilling operations. Through world-class presentations, practical discussion,
and the best reference and instructional materials available, delegates hone
their knowledge of basic drilling technology and how it relates to avoiding
NPT.
Preventing stuck pipe incidents can save
thousands of dollars in non-productive time. Stuck Pipe Prevention covers
topics to eliminate or greatly reduce stuck pipe incidents on your rig.
This course emphasizes on the prevention of stuck pipe and the team concept is
used throughout the course, explaining the contribution and value of every
crewmember in the goal of keeping the pipe free.
This training course will feature:
- How
to predict and make the contingency plan to prevent the stuck pipe
- How
to write the proper report for the stuck pipe incidents
Training Objectives

Instability, Hole Cleaning, Differential Sticking, and Wellbore Geometry)
- Assess
mechanics of wellbore stresses and the impact on wellbore stability
- Analyze
trends to identify early warning signs of developing wellbore problems
- Implement
effective drilling and tripping practices
- Make
cost-effective choices in planning fishing operations

Training Methods
How will this Training Course be Presented?
This course will utilize a variety of proven adult learning
techniques to ensure maximum understanding, comprehension and retention of the
information presented. The daily workshops will be highly interactive and
participative. The course will include all types of stuck pipe and the
recommended procedures for preventing by analyzing the operations, how to free
the stuck pipe in case of occurrence, hole cleaning and impact on the problems,
and fishing tools and jar energize.
