Remedial cementing operations are done to repair the primary cementing problems and also to treat conditions arising after wellbore cementing has been done. Remedial cementing is done either by doing squeeze cementing or by placing cement plugs to repair the cement related problems. This problem is common in new wells when the cement is not properly placed during development or when poor cementing is done. This problem is highest in the newly developed areas as the cementing is primarily done while drilling the well.
Remedial cementing, sometimes referred to as squeeze cementing, is the process of using pump pressure to inject or squeeze cement into a challenging void space at a desired location in the well. The operations may be performed at any time during the life of the well such as drilling, completions or producing phases. Depending on the remediation need, cementing can be performed above or below the rupture gradient of the exposed formation (high pressure squeeze and low pressure squeeze, respectively).
Remedial cementing is commonly used to:
- Discarding a non-productive or depleted zone or the entire well
- Remedy a deficient primary cement job such as incomplete coverage of cement
- Seal lost-circulation zones
- Repair casing leaks
- Change the water/oil or gas by shutting off the breached zone
- Modify injection profiles
Remedial cementing is an operation undertaken to remedy a problem and presents the challenge of placing the proper amount of cement in the targeted location. The increasing trend in the remedial cementing market is set to continue further with the current surge in offshore and onshore activities and unconventional resources exploratory activities.
