CASE STUDIES
Validating Formation Annular Seals for Well Abandonment
Challenge
Determine whether competent formation seals could be technically demonstrated for well abandonment.
Approach
The operator’s P&A and geology teams worked with Cementing Performance to integrate cement evaluation and casing condition data with cementing history and geological information.
Decision Supported
The operator confirmed formation seals providing annular isolation across uncemented intervals and validated the barriers required for well abandonment. No further remedial work was required.
