Advanced Well Completion Design

Introduction

This LAKESHORE ISL Advanced Well Completion Design training provides in-depth information on the impact of workovers and completion design in maximizing field production and increasing recoverable reserves. It also emphasizes the importance of a team concept as a determining factor in operations success. Participants will gain a greater understanding of how to apply advanced technologies to designing and executing workover jobs, and how to select the best operations method to perform the task in the safest, most efficient manner.

This training will feature:

• Develop a high level completion strategy for wells in a variety of situations
• Select tubing, packers, and completion flow control equipment

Objectives

By the end of this training, participants will be able to:

• Appraise / design a suitable flow barrier strategy and suitable intervention strategy
• Make recommendations on installation and retrieval practices for tubing, packers, etc. in different well types
• Identify key features / applicability of the main sand control, frac pack and well stimulation options

Training Methodology

This training will utilise 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.

Organisational Impact

The organisation will gain, in sending their employees to attend this particular training, the following:

• Reduction in the cost of the well and the proper selection of production string
• Extending the well life and control it, achieve the optimum production
• Ensuring the well integrity and avoiding all risks

Personal Impact

• Obtain integrating knowledge of well completion design
• Hone their knowledge and get the self-confidence in designing proper completion
• Get the latest technology in well operations
• Solving and avoiding the problems which impact on the optimum production, and well integrity
