Drilling & Reservoir Training
Introduction
  • The training program provides details knowledge of Fishing Tools and their application.
  • The course provides comprehensive and complete coverage and handling in the industry to understand and master the main issues that lead to stuck pipes. Stuck pipes are the main source of (NPT) Non-Productive Time that is associated with drilling operations, loss of circulation, and wellbore instability. Non-productive time costs companies thousands of dollars and preventing such incidents could save a lot of funds.
  • How do you keep a pipe from drilling stuck?

Stuck pipes can cost an organization thousands of dollars in costs if not handled or eliminated with high efficiency. This course from Zoe will produce professionals who can handle stuck pipes with a high degree of efficiency and reduce the operational costs that a company might face.

  • Some of the main skills that will be delivered include how to analyze predict and make a contingency plan to avoid or in case there is a stuck pipe.
Objective
  • Operational knowledge to specify tools and procedures to ensure the recovery of tools and/or equipment left downhole.
  • Evaluate the techno-economics and risks involved in fishing as compared with other alternatives such as sidetracking.
  • Ability to specify tools and procedures to ensure the recovery of tools and/or equipment left downhole under supervision.
  • Evaluate the economics and risks involved in fishing as compared with other alternatives such as sidetracking.
  • Monitor fishing operations in the field and provide recommendations regarding the tools and methods being used.
Audience
  • Drilling superintendents who need to understand the main concepts of stuck pipe prevention and fishing in drilling.
  • Tool pushers that will interact with stuck pipes
  • Senior drillers who will be undertaking drilling to prevent stuck pipes in the future.
  • Drilling engineers play key roles in stuck pipe prevention through design and actualization.
  • Mud engineers who seek to understand the problems associated with stuck pipes.
  • Drilling supervisors are interested in knowing more about stuck pipe prevention.
  • Any other professional whose interest is in stuck pipe prevention, fishing in drilling, tools, and their operation.

Methodology

This course combines sound engineering, operation and maintenance principles, applicable standards, and best industry practices for reliable and cost-effective process plant systems. Delegates will be encouraged to introduce problems of their own for discussion and analysis. Copies of all lecture materials, case studies, and workbooks will be provided. Group discussions will be carried out on problems faced.  This training program is lecture-based and customized to the needs of the audience, providing a meaningful experience for personnel who work in petroleum plants. Daily sessions include formal presentations, prepared in PowerPoint, interspersed with directed discussions and case studies. In addition to formal lectures and discussions, the delegates will learn by active participation through the use of problem-solving exercises, group discussions, analysis of real-life case studies, etc. Many relevant videos will be shown during the training.
