Cement Bond Log Test

Cement Bond Log Test - The cement bond logs (cbl) gives a continuous measurement of the amplitude of the first casing arrival at a receiver spaced 3 ft from an acoustic transmitter. Precise cement sheath evaluation with the acoustic cement bond log service from baker hughes. The use of acoustic tools in the evaluation of cement placement is an established practice. Acoustic logs do not measure cement quality directly, rather, this value is inferred from the degree of acoustic coupling of the cement to the casing. A cement bond log (cbl) documents an evaluation of the integrity of cement job performed on an oil well. To test for a microannulus, the pipe is logged under pressure to see a reduction in 3’ amplitude, loss of pipe arrival in vdl and improved radials. Below is a cement bond log showing you an amplitude track and five different intervals to interpret. Simply, it gives the % of the pipe circumference cemented. Select the best interpretation for each interval based on your knowledge. The log is typically obtained from one of a variety of sonic.

The presence of a microannulus indicates. The distribution of cement around the casing is reported by the bond index. To test for a microannulus, the pipe is logged under pressure to see a reduction in 3’ amplitude, loss of pipe arrival in vdl and improved radials. A representation of the integrity of the cement job, especially whether the cement is adhering solidly to the outside of the casing. Reasons for bond log • bond logs are run to determine: Interpretations of these logs sometimes do not. Radial analysis bond log (ral) •improves cement evaluation capabilities compared with conventional cbls. The current edition, cement sheath evaluation api 10tr, is available through api.
