Well Integrity - Cement Placement Evaluation

Cement integrity is critical for the whole well integrity as it is the first barrier in between the reservoir (P and T) and surface.
Measuring cement integrity remains a challenge. Most tools measure an acoustic property of the cement while integrity depends more on permeability. Hence the need to be able to read and interpret with the greatest confidence  as possible the logs.

The objectives of the two days are :
- Understand how to assess the quality of a sonic or ultrasonic log i.e can the information contained in the log be trusted
- Be able to read the logs without being tool specialists
- Be able to make the link in between the log and the cement job.

    Day 1

    Exercises on understanding how to assess the quality of a sonic or ultrasonic log i.e can the information contained in the log be trusted and be able to read the logs without being tool specialist.

    Day 2

    Real logs (ultrasonic and VDL) are given to the Participants. The instructor plays the role of the cementing company. The Participants have to take the decision to perforate the well or not at the depths specified and to suggest improvements to the cementing job.
