OUTLINE
This course covers the fundamentals of modern well completions design, teaches the architecture of oil and gas wells, investigates the mechanics of the hardware, discusses methods for completing and servicing wells, and reviews procedures and practices of well planning and design. It presents important aspects of equipment engineering, including specifications, materials selection, design review and failure analysis. It discusses methods for production string deployment, well intervention, and well service and repairs.

The program covers traditional platform and subsea well completion, vertical, slant, extended reach, horizontal and multi-lateral well bores. Emerging techniques for constructing, completing and servicing these wells receive a considerable coverage.

TARGET ATTENDEES
This course is aimed at engineers who have to acquire an in-depth knowledge of the hardware, the architecture, the design, and the operations of production wells. The course is on a graduate level and assumes basic knowledge of engineering mechanics. However, senior well service supervisors and other professionals interacting with well operations will benefit from the course.

AIMS
To developed an in-depth understanding of the systems, components and procedures used to complete oil and gas wells. To develop skills needed to select and maintain well hardware. To develop knowledge needed to design, audit, and assess well completion and well operations. To understand the trends of well completions and well service evolution, and to comprehend the on-going efforts to stretch the limits of existing well construction and servicing technologies.

LEARNING OBJECTIVE
Having attended the course, participants will:

• Understand the issues and the parameters that govern the configuration, the architecture and the detailed design of a well.
• Be capable to translate operational and production requirements to well construction design and hardware selection considerations.
• Be familiar with the hardware of the well and it's principles of operation. Be capable of specifying equipment and performing design review and fit-for-purpose assessment.
