End of Well Reporting and Performance Measures
Effective reporting of well clean up is crucial for developing best practice and looking for
opportunities to improve or reduce cost.
Key elements for reporting are:
• Daily events to include all time associated with clean up
• Record of measurements (e.g. NTU/solids content)
• Tracking of performance (e.g. time to reach NTU target/interface volumes)
• Lessons learned
• Target time vs. actual
• Tracking of brine, i.e. volumes received, built, lost, sent for reclamation
A report should capture the following areas:
• Fluid designs and properties
• Flow rates
• Pill volumes
• Volumes circulated
• Interface volumes
• Equipment used
• Materials used and costs
• Pipe movement during displacement
• Time breakdown
• Fluids cleanliness vs. time during circulation
• Surface clean up
• Target vs. actual for cost and time
• Pipe movement and torque measurements
Identification of performance parameters to be measured should include:
HSE Related:
• Days Away from Work Injuries
• Recordable Injuries and Illnesses
• All Accidental, uncontained spills or discharges
• Total Manhours on site for this service and operation
Cost Related:
• Total Completion Fluids Cost
