01. Lesson 1.00: Course Introduction

Hi and welcome to Introduction to PVT. My name is Christoffer Duus and I work at Whitson as a PVT consultant and working on development of PVT software. So I'll be going through PVT now with you, which will be quite a fundamental course. We'll keep it practical. We'll start with some general information here.

02. General Information

We will try to keep it relatively short, make it a 1/2 day course, maybe 2 or 3 hours. And I'll also attach some additional slides, additional files, so you can look into some additional material. We also have some additional material in the appendix, so if there's something you're curious about and would like to look into, you could always find that there.

03. Disclaimer

As I mentioned, we'll try to keep things practical. We won't dig too much into the deep PVT areas, but another person from Whitson will have a follow-up course as well, which will go deep into fluid modeling and PVT and kind of build on this introductory PVT course.
We'll try to keep it very practical, as I mentioned, not go into theory too much but kind of understand how PVT can influence your fluid behavior or your production processes.
We won't go into QC and such and detailed analysis. We'll just kind of briefly touch on the various topics to get a good understanding. And we'll also not go into niche areas, we'll try to keep it general as well.

04. Course Progress 'Logic'

We'll start with going through petroleum fluids, and then how you would sample those fluids. Then, how would you utilize those sample data to get some laboratory experimental data, your measurements. And then how you can utilize that data to build a fluid model which will describe your actual hydrocarbon fluids, and then how that can be used in engineering purposes.

05. Course Goals

We'll start with classifying reservoirs. So of course for oil, we divide that into 2 separate oils based on the GOR. So typically if we have a very low GOR, it will be a black oil. We'll go through a volatile oil. And then when you have the switch going from an oil to a gas you could have a near-critical fluid, and then we could have gas condensates, wet gas, and dry gas. So we'll go through the differences between them and how that classification is done.
Also, when we do collect samples, we tend to differentiate between in-situ and reservoir representative samples. So we will dig into what that means as well.
And then we'll also talk about the inputs for an EOS model. What do you actually need to gather in order to build one for the guys who will actually sit and develop this later on.
And then we can see how you can estimate thePVT properties from that EOS model. Basically, what are your reservoir fluid properties?
And then, we'll also look into calculating original oil in place and original gas in place for both oil reservoir, gas reservoir, and the combined 2-phase system.
We'll also take a look at the PVT report, and then we can understand how the data is presented and what is actually calculated vs. measured.
And that's it for basically my introduction here. And then we'll go ahead to PVT for the first time.
