01. DCA Reserves and Economics - Lesson 1.01: IntroductionYears ago, a friend of mine took his first job in the petroleum industry at a small private operator in West Texas. He sat down in his office the first day and the owner came to see him. The owner sat down and said, now listen son, I know that you've spent 4 years studying petroleum engineering at one of the finest schools around... Texas A&M. But notwithstanding that fact, you are no longer a petroleum engineer. He said, from now on, you're an economics engineer. Your job is not to tell me how many barrels of oil or MCF of gas we're going to produce, your job is to make sure that our company makes money. Maybe I'm the only one but for me, I can lose track of that fact. And what we're going to do in this course is try to keep that issue, that ultimate issue front and center.
02. ObjectiveWe're going to talk about what it takes to make a quality estimate of future cash flows so that we can enable profitable decisions. Quality means fit for purpose, useful for the purpose. So I think of it with 3 criteria:.
03. QualityQuality engineering or quality cash flow analysis first must be reliable for the question at hand. It's not that one analysis is complete and useful for all time and all situations. Often the analysis runs in an iterative and progressive manner, and we'll talk more about that. But it only has to be reliable for the decision at hand. And that helps people like me to twisted off and sometimes not be done where it should be, because that's the second criteria.
04. Volumes, Prices & CostsThe first part is volumes. What will the oil and gas wells produce in the future? That is subject to engineering. Geology as well. We can do lots of work to try to define that part of the equation.
05. Diminishing Cash FlowSo what we get is a diminishing cash flow. It starts high at the beginning, gets smaller with time. All else being equal prices can outweigh that, but it accumulates.
06. Accumulated future profits must be converted to present timeAnd we have to decide how to translate those future accumulated cash flows back to a particular point in time. And make the decision, does that present value or some other method, some other kind of economic yardstick, does it justify the expense? How much can we pay? How much should we pay. Should we drill? Should we not drill? How do we balance the issues of costs, capital costs and future net income?
07. Cash Flow TableNow all of those variables end up on a cash flow table that looks like this. This is a portrait layout, others are very commonly... I'm sorry, this is a landscape layout. Others are very commonly portrait. But you can see all of the pieces. A cash flow, like any work, must have a label, must have an identifier to explain what it is. And then we have a column for years for orientation. After that, it flows left to right. Volumes, prices. There are some columns there for revenues, a subtotal. Then we have various kinds of costs. Cash flows at the right, net cash flows, cumulative cash flows. And then yardsticks at the bottom.
08. Each part requires analysis, but...And those streams of incomes are the pillars of the overall analysis that we're building. They're not the foundation, they're not the ultimate, those are the pieces. They are very important pieces, everything else relies on them.
09. ...analysis is only part of a larger processBut at the foundation of the larger process is data. Collecting data and putting it into some sort of useful form. Everything that we do is built on that foundation. And if you want to spend a lot of time remodeling your work, just change that data foundation. But then we go into the various kinds of analysis; LOS analysis, price differentials, variable cost, gathering and processing costs. When we get all of those pieces together, then we can make a holistic view of what's going on in that situation, in the cash flow that we want . That's not still the ultimate. Ultimately, we want to make a decision. What are we going to do? What does this mean? And what does it mean not just here, for this one cash flow, what does it mean in the context of the business?
10. Course OverviewNow we're going to break this down into 5 parts. Very fancy here, we're going to begin at the beginning. My dad's a preacher. His narrative style is maybe a little different, but we're going to talk about how to start a project. It is said from research that an expert spends more time than an amateur planning his work, but less time performing it. Lets talk about how to start right as one of my early mentors used to say.
11. Generic Cash Flow TableAnd at the end of that, I hope you'll be able to make a cash flow analysis that looks kind of like this. Now, this one is a portrait view, but it's the same basic layout. We have headers at the top. Years, volumes, prices, costs, cash flows and yardsticks.
12. Me...In the 25 years I've been at this career, I've worked all over the world helping people to make decisions. I've been the engineer. I've been the engineering manager. I've been the reserves manager. I've been the executive making the decision. And I've been the expert witness whose job it is to come along at the end of the day and decide whether people make good decisions or not decisions. Now I said before that we want to focus on making money but the truth is, we don't actually make money. We don't write it, we don't print it. And in truth, we don't even make oil and gas. We can't create it.
13. Analyses and Holes in the GroundWhat we do make are analyses and holes in the ground. And we hope that we've made good decisions, the juncture of these two, interface with these two, so that we get oil out of the ground, so it's produced naturally. But all we have control over are our analyses, holes in the ground and their intersection at decisions, and that's what we want to talk. Building good analyses so we can make good decisions. Now let's get started.
14. A Note of ThanksSo notwithstanding that I just said let's get started, let's do a detour. A note of thanks and a little bit of a commercial. I've been teaching the materials that we're going to talk about for 5 years. But some of those materials have been codified into a course that I teach for the American Association of Petroleum Landmen called Petroleum Economics. This course is designed for non-engineers to give a survey of the kinds of decisions we make and how we build cash flows.
