Well diagnostics
Annulus Pressure Investigation
Field reference · Offshore Malaysia
Problem & challenge
Annulus pressure behaviour needed to be understood to confirm whether communication was present and to quantify active flow.
Objective
- Evaluate annulus pressure integrity, determine fluid level and quantify any active flow or crossflow.
Solution
APIS annulus pressure integrity surveillance was combined with EchoPulse liquid-level measurement and Quantis direct flow metering.
Result
Annulus communication and flow behaviour were identified, giving a clear basis for the next integrity decision.
