Cement Remediation

Disciplines: Completions | Drilling

Course Description

This one day training course focuses on the repair of channels, voids and leaks in a cemented wellbore. Poor cement coverage and lack of zonal isolation in the casing-borehole annulus often leads to production of undesired fluids and reduced hydrocarbons production, disposal problems, reservoir pressure decline, loss of hydrocarbon reserves and other problems. Objective of the course is to evaluate and discuss various technologies used to repair wellbore communication paths due to wellbore aging that can develop allowing fluid to migrate from the high pressure downhole strata through leakage paths in the cement containment.

Learning Level

Intermediate to Advanced

Course Length

1 Day

Why Attend

Poor cement coverage and inadequate zonal isolation affects nearly every aspect of a well during its life. This course will give participants a better understanding of some critical well safety and integrity issues and methods to repair wells that have reliability issues, including sustained casing pressure (SCP).

Who Attends

This course is designed for asset managers, drilling and completion engineers, petroleum engineers and geologists, independent producers, production managers and engineers, reservoir managers and engineers, field supervisors, company executives and officials, field personnel with operating and service companies.
