Read MoreCement bond tools cbt-ha are sonic logging tools that have one omni-directional transmitter and two omni-directional receivers.Cement bond log tools are used to evaluate the effectiveness of cementing operations by - measuring the attenuation of the acoustic energy in the casing-to-cement interface.
Read MoreThe cement bond logging tools have become the standard method of evaluating cement jobs.They indicate how good the cement bond is.A cement bond log cbl documents an evaluation of the integrity of cement job performed on an oil well.It is basically a sonic tool which is run on wireline.
Read MoreThe segmented cement bonding tool sbtis a new type cement bond logging tool.The tool divides casing, cement annulus and formation into six segments.The sensors are pushed against well wall for measurement to achieve high accuracy, unaffected by casing fouling, micro annulus, fast formation and mud property change.
Read MoreSummary.Lightweight cement can present unique challenges to efficient and accurate evaluation of cement-sheath integrity.Standard bond-log tools require high compressional bonding to casing to observe an attenuation of the sonic signal that is set up inside the casing.
Read MoreThese tools are ultrasonic measurements, but they dont give you the 360 degree cement impedance maps like the modern tools do.Each group has their own advantages and limitations when it comes to detecting zones with good cement bond.We will start with the classic cement bond.
