01. Fundamentals of Wellbore Flow - Lesson 1.01: Overview of Well Flow Hello everyone. First of all, I'd like to welcome you all to this course. This course is titled Fundamentals of Wellbore Flow. Our main purpose/objective here is to give you a basic understanding of wellbore flow. And our motivation to do so is coming from prediction abilities or capabilities for reservoir performance or monitoring of the production from a given well. That typically requires the bottomhole flowing pressure. Bottomhole flowing pressure can be obtained by having a downhole gauge, pressure gauge; that is the ideal case. However, we may not have the bottomhole gauge. If we don't have the bottomhole gauge, what we're going to do is estimate the bottomhole flowing pressure based on the surface measurement or wellhead measurement of the pressure. What happens between wellhead and the sandface then becomes really crucial. How do I estimate bottomhole flowing pressure knowing the wellhead pressure? That is the primary objective of this course. There are a lot of things to cover. I'm going to try to start with the simple basics, and as we go along, we will go deeper into the subject matter. During the course, we will have a lot of example problems and homework assignments. We will also have some tests along the way. Without further ado, let me start with the introduction. I will cover introduction in 2 lessons. First, I will go over the well flow.
