DACC IRP Volume #26 - Wellbore Remediation
IRP 26: Wellbore Remediation contains recommended practices to re-establish wellbore integrity and/or ensure hydraulic isolation between porous intervals. The IRP assumes the type of remediation required has been identified through regulatory requirements or existing well information.
Information about remedial cementing was originally provided in IRP 25: Primary Cementing. The Drilling and Completions Committee (DACC) decided (2017) to expand on remedial cementing and create one document for all wellbore remediation, including the use of pumpable products other than cement.
The IRP discusses the data analysis, job design (i.e., technique selection and material selection), job execution and post-job evaluation of the following remediations:
• Groundwater Protection
• Surface Casing Vent Flow (SCVF) and/or Gas Migration (GM) Repair
• Porous Zone Isolation
• Water or Gas Shutoff and Injector Conformance
• Completion Interval Isolation
• Casing Repair
