Ensuring rock-to-rock barrier restoration for fluid pressure isolation in the annulus
between dual casing strings.
Complex Remediation for Dual-Casing Isolation
Results:
• A dual-casing section milling operation was safely executed using a Kelly Rig.
• As a critical part of the well Plug and
• Abandonment plan, rock-to-rock barriers were effectively placed across both casing strings.
• Successfully prevented hydrocarbon migration to the surface.
• Ensured protection of the freshwater reservoir from contamination
• Eliminated the need for 112 days of conventional pilot milling from the surface.
