Description
A-One Oil Cement Bond Logging Tools evaluate the bonding quality between the casing and cement as well as between the cement and the formation. It can provide the key indicators for assessing the sealing effectiveness of oil, gas, and water wells.
The CBL90C includes a 3-foot sector receiving probe, and a 5-foot VDL (Variable Density Log) probe. Each sector covers a 45° cross-section, allowing for a 360° assessment of the cement bond integrity.

Features
◆ Cement Bond Logging Tools adapting the ultrasonic probe heads are structured in an independent design, offering strong reliability and convenient maintenance.
◆ Owning the large-capacity storage system, high-speed data acquisition frequency, and ultra-fast data reading speed, enabling refined and rapid well logging.
◆ 360° evaluation: Each sector covers a 45° section, ensuring comprehensive evaluation of bonding integrity.
Applications
◆ Perform well logging in operations where cable provision is not possible.
◆ Provide a 360° cement bond log (CBL) image.
◆ Measure the quality of cement bonding in both horizontal and conventional wells.
◆ Quantitatively evaluate the bond index of the first interface, and qualitatively assess the bond index of the second interface.
FAQ
Q: Can Cement Bond Logging Tools be used for joint logging with an electromagnetic thickness – EMFD43C and a Multi - Arm Caliper Logging Tool?
A: Yes, we it can.
