Halliburton’s ACX™ Service – Key Features
Uses an array of acoustic sensors
Finalized product capability:
Detects oil/gas/water flow in tubing, casing annuli, behind casing, and downhole components such as packers
Geometrically isolates phase movement point within 1-m depth resolution
Estimates radial location of communication
Characterizes detected flow:
Estimates communicational flow rate (based on empirical models)
Estimates flow composition – oil, gas, water, multiphase
