Instructor: Roger L. Nutt 5 days
Who should attend:
Petroleum engineering and drilling managers; petroleum, reservoir, drilling, production and wireline service company engineers; petrophysicists and log analysts; technicians; and anyone who needs to understand what production logs and cased-hole surveys can tell us about how the well and adjacent reservoir are behaving.
Based on the highly successful Reservoir Monitoring and Production Log Interpretation course which Roger Nutt taught for OGCI for many years, this course has been re-designed. It includes Cement Bond and Casing Corrosion logs and their interpretation, but focusses particularly on production logs and reservoir monitoring surveys, including TDT, C/O, Gamma Spectroscopy and Water flow Log. The more you know about cased hole logs, the more you can expect to learn about designing the logging program, engineering the surveys, interpreting the results, and understanding what the answers tell you about the behaviour of the well and surrounding reservoir. You will learn by solving for yourself a host of real, practical and down-to-earth problems from a wide variety of wells and situations.
Course Content:
What you will learn...
How to integrate all the broad and subtle indications which your production and reservoir monitoring logs give you to understand what is happening inside your well and its environment. How to be sure where the different fluids which enter the casing are really coming from... and where your injection gas or water is going. How much of the apparent behaviour of your well is caused by the reservoir as a whole - and how much is a result of unseen local disruptions to the flow pattern caused by the well and its surroundings. Perhaps most important of all: how much oil and gas are you leaving in the reservoir?
