Deepwater completions must address challenges from installation to abandonment. It starts with a field development plan with well count, trajectories ,and targets to meet economic, production, and recovery objectives. Completions must provide efficient installation, avoid intervention, and handle production over long intervals of often highly variable reservoir properties.
Optimizing perforation designs, predicting and controlling sand production, and designing reservoir stimulation programs are critical components of choosing the right completions program and optimizing production.
The majority of deepwater wells require some form of sand control to stabilize the reservoir, prevent the migration of sand and fines into a wellbore, and enhance productivity.
Minimizing formation damage during completion installation often relies on mechanical barriers which serve the dual purpose of providing mechanical integrity.
Balancing the ability to reconfigure an intelligent completion well during the production phase versus the cost and future production unknowns presents a significant challenge in deepwater completion design.
Fluids designed specifically for deepwater completions address issues associated with operational and well integrity, compatibility, and flow assurance.
