About the Well

• Country:  Malaysia
• Type of well: Oil producer (Dual string)        
• Deployment system: Electric Line
• Objectives: To detect the source causing the pressure build-up in B-annulus.

Well data while logging

• Tubing Pressure: 100 bar
• A-annulus Pressure: 90 bar
• B-annulus Pressure: 2-8 bar

Fluids in the well while logging

• Tubing: Oil
• A-annulus: Gas
• Leak rate: 14.7 l/min

Logging data:

• Line speed:  9 ft/min
• Depth correlation: - 4 ft

Results: Acoustic energy with various intensities caused by flow behind 9 5/8” casing is seen. Warm colors are indicating higher levels of energy.
