Course Objective

Learning Objectives

Pre-requisites

To provide an overview of the fluid flow equations and methods to estimate well production capacities and conditions for optimum flow, as applied to Conventional, Unconventional or Coal seam gas exploitation.

Students will learn and understand how to:

1. Determine the flow rate at which an existing oil or gas well will produce considering wellbore geometry and completion limitations, by natural flow or artificial lift.

2. Determine under what flow and time dependent conditions a well will load, become unstable or die.

3. Select the most economical time for the installation of artificial lift and to assist in the selection of the optimum lift method.

4. Optimize the system to produce the objective flow rate most economically.

5. Diagnose each component in the well system to determine whether it is restricting the flow rate unnecessarily.

6. Identify ways to increase production rates.

1. Students should have an background in Petroleum, Mechanical, Electrical or Chemical Engineering.

2. Students should be familiar with the components of a petroleum production system.

3. Ideally, students should have some experiece in production, drilling and/or completions operations.

4. Lecture intensity level to be adjusted to the average knowledge gaps of the class.

There are numerous oil and gas wells around the world that have not been optimized to achieve an objective rate efficiently.

In fact, many may have been completed in such a

manner that their maximum potential rate

cannot be achieved.

Many wells placed on artificial lift do not achieve

the expected efficiency due to other interactions

in the production environment.

Integrated production model, also known as

system’s nodal analysis, is defined as a systems

approach to the optimization of oil and gas

wells, and is used to evaluate thoroughly a

complete producing system.

Every component in a producing well or all wells

in a producing system can be optimized to

achieve the objective flow rate most economically.

All present components, beginning with the static

reservoir pressure, ending with the separator,

and including inflow performance, as well as

flow across the completion, up the tubing

string (including any downhole restrictions and safety valves), across the

surface choke, through horizontal flow lines, and

into the separation facilities- are analyzed.
