Course Description
This Stuck Pipe Prevention & Fishing Operations seminar 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 seminar 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 seminar emphasizes on the prevention of stuck pipe and the team concept is used throughout the seminar, explaining the contribution and value of every crew member in the goal of keeping the pipe free.
The Training Course Will Highlight ?
This training seminar 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 Objective
By the end of this training seminar, participants will be able to:
- Identify mechanisms and risk factors that lead to stuck pipe incidents (Wellbore 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
Target Audience
This training seminar is suitable to a wide range of professionals but will greatly benefit:
- Mud Engineers
- Drilling Supervisors
- Drilling Engineers
- Tool Pushers
- Senior Drillers
- Drilling Superintendents
Training Methods
This training seminar 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 seminar 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.
