Cement Integrity (DRI43)

Description

Cement log interpretation is often left to the logging company. There is very little input from the cementing engineers. So the decision to do an eventual remedial job is very often difficult to take. The objective of this course is to give the drilling engineer / company man / fluid specialist the knowledge required to challenge the log interpretation for a wiser decision on hypothetical remedial jobs.

Course Level: Advanced
Duration: 4 days
Instructor: Benoit Vidick

Designed for you, if you are...

A drilling engineer
A company man
A fluid specialist or superintendent

How we build your confidence

This course will use a lot of logging examples and participants are strongly encouraged to present their own logs.
One full day is devoted to an exercise: Participants will have to answer to some completion questions (perforate? What depth? Do something different on the next jobs?) based on a real case history. The instructor will play the role of the cementing company.

The benefits from attending

By the end of the course you will feel confident in your understanding of:

The sonic and ultrasonic logs
The cementing job parameters which can affect cement logs
Other non-logging techniques which can be used to evaluate a cement job
