PROGRAM'S BACKGROUND

This program will provide well testers with a comprehensive theoretical and practical knowledge of well testing operations. Participants will also be exposed to different well testing analysis techniques. Emphasis will be placed on the practical aspects of well testing and a number of relevant examples will be presented as well. This program builds the skills necessary to ensure that well construction plans achieve production or exploration goals while managing risks to honor time and budgetary requirements. The program emphasizes critical decision making skills through extensive use of real world practical examples. Instructors are experienced well designers who facilitate learning in this unique case study environment.

This program also stresses practical application of well test theory to design and interpretation of pressure transient tests. An integrated approach to well test interpretation is emphasized throughout the program. Class exercises involving hand calculations and simple spreadsheet applications will reinforce the concepts covered in class. Concepts will be illustrated by both synthetic data sets and real field examples. Participants will be able to apply the knowledge and skills in their job assignments upon program completion as they will learn how to analyze well tests in naturally fractured reservoirs, perform draw down testing and reservoir limit testing and effectively carry out two rate flow test analysis, variable rate flow tests and perform a multi rate flow test analysis. This program brings together a documented planning and design process, maximizes drilling efficiency and transfers the execution plan to the well site for implementation. Participants will learn to analyze inefficient practices at the well site and utilize their newfound skills to improve the operation.
