01. Lesson 1.01: Introduction

Hi and welcome to a Practitioner's Guide to Well Test Design and Interpretation.

02. About the Instructor

My name is Dylan Lougheed. I'll be your instructor for this course. A little bit about me: I graduated with a Bachelor of Computer Engineering actually, and wasted my time with a general degree in biology before I later entered the industry and learned everything I could learn about petroleum engineering. I also completed a master's, or a MBA, at U of C in 2016.

03. About the Instructor - 2

So there's a picture of me when I used to have hair. I was an overseas volunteer for a year doing database instruction and teaching people how to build databases (even Excel) in West Africa. I then spent some time in the high-tech industry working for a high precision GPS company doing some coding. And then I became a reservoir engineer by accident in 2011 when I left the high-tech sector to join Fekete Associates. And there, if you are an engineer, you need to learn how to do reservoir engineering. And so I spent many early hours and late hours there getting taught as best as I could by some of the best in the industry around well testing. And then throughout most of that decade I was involved in supporting what was called the Fekete Well Test software. Of course that later became IHS Markit and at that time I did a lot of well test interpretation. I worked with a lot of clients who I would guide through doing well test interpretation. And I spent a brief time at NCS Multistage before coming to SAGA Wisdom.

04. About the Instructor - 3

I've written and co-authored a few SPE papers. Many of those have to do with well test analysis.

05. Recent Interests

And my recent interests are in applying well test analysis to CO₂ injectors and other disposal wells, as well as the idea of active learning and building companies.
So this course is going to be a little bit different in that I'm trying to throw in some exercises before we actually go through the full explanation of the material. In that way you can get tested before you learn. I'm interested in your feedback on how that goes. We will see as we progress through the course.

06. Learning Objectives: Understanding Well Tests

So what are you going to learn in this course? Well, first and foremost I want people to understand what a well test is and understand why would you test and when to test. These objectives and this intro-section, by the way, is for anyone. So some people may find it a little too introductory and may wish to skip to the later sections. Other people who maybe don't come from a reservoir background may find some benefit in understanding. And hopefully I can sell you on the idea of why certain techniques in well testing like pressure transient analysis can give you certain reservoir properties.

07. Learning Objectives: Pressure Transient Analysis

We're going to get into pressure transient analysis and understand a lot of the different concepts. We're going to review flow regimes, we're going to go through BourdetDerivative analysis, we're going to do some modeling and forecasting of well performance.

08. Learning Objectives: Deliverability

I'm also going to cover deliverability testing. So by the end of that lesson you should be able to understand and define properly what is well deliverability and understand how to create and analyze these deliverability tests.

09. Learning Objectives: Wellbore Effects

We'll talk a lot about wellbore effects (in Louis Mattar's world). Well testing is more than just pressure transient analysis. There are a lot of wellbore effects that come into play when we're doing well testing and sometimes you can learn a lot about the wellbore inadvertently when you do a well test. I'm going to go through test design and why that's important.

10. Learning Objectives: Injection Tests

We're going to get into injection tests and understand what can be obtained from injection tests.

11. Learning Objectives: Interference Tests

Finally, we'll briefly cover interference testing and its application in both conventional and unconventionals.
So that's it for this introduction. I hope you stick around and go through the course with me.
