Since cementing procedures form the basis of any gas or oil well, they are essential to well life. If every casing project is not completed with effective cementing operations, well integrity is jeopardized. Similar to a home's foundation, cementing serves as the cornerstone for effective well performance.

Course Objectives:

By the end of this training course, participants will learn to:

Calculate Volumes of Cement, Mix Water and Additives
Understand the critical parameters for any cementing operation
Select displacement rates for effective mud removal
When to select Two Stage Cementing
Select the proper Additives based on Well Conditions
Read and perform Interpretation of Cement Bond Logs
Understand Special Cement Systems
Select Casing Hardware for successful Cementing Operations
