... integrity. One of many ways to evaluate this is by running Cement Bond Log (CBL). Well condition prior, during, and after cement placement contribute high impact on the result of CBL. Aside from that, temperature and pressure changes also give significant outcome to CBL result. In this paper, some...

... by the tool with more circumferential coverage of the pipe than before. The tool performs this in real time at normal logging speed, thus saving operation and rig time. When the new ultrasonic radial scanner tool is combined with the new multi-sensor caliper, the magnetic flux-leakage tool, and the CBL...

...J.J. Jutten; E. Corrigall Summary We intend (1) to show that formation characteristics affect the cement bond log (CBL) signal in most wells, (2) to prove that high-amplitude CBL's obtained in concentric casing-string configurations are often an artifact resulting paradoxically from the excellent...

... ABSTRACT A new "radial" cement bond instrument, the Micro CBL, has been developed to measure the quality of cement to casing bond. The instrument is capable of measuring the quality of the cement bond both vertically and circumferentially. Four arrays of sectored transmitters and receivers...

...L.E. Albert; T.E. Standley; L.N. Tello; G.T. Alford Summary The introduction of new ultrasonic and ratio logging techniques has dramatically transformed cement evaluation. Previous methods [cement bond logs (CBL's)] that used a low-frequency (appx. 20 × 103-cycle/sec [appx. 20-kHz]) acoustic signal...

.... The introduction of foamed cement in the oil field by the major well service companies presents a new challenge to the well logging companies. These new foamed cements showed little effect on the amplitude curve of early CBL logs. Because of this lack of response, it became important to determine the validity...
