  • Evaluate cement bond to both pipe and formation

  • Indicate channels or intervals with only partial bond

  • Locate free pipe and top of cement

With more than 75 years of experience, Halliburton has the right tools and the superior on-site capabilities to provide reliable cement bond logs in any downhole environment.

Full Suite of Tools Halliburton's array of nine different CBL tools produce accurate bond logs in any casing size – from 2 in. to 20 in. – over a wide range of temperatures and pressures.

Bond Logs in Hostile and Slimhole Environments Haliburton's Hostile Full Wave Sonic tool can provide reliable bond data in temperatures up to 500°F and pressures as high as 25,000 psi.And with an OD of just 2.75 inches, the HFWS is also ideal for slimhole applications.

  • is cement bond log is across a section containing free pipe. e log

exhibits a classic MSG signal of very straight lines with a casing collar pattern near the center of the log. e volumetric map shows approximately 97% liquid while the amplitude curve is reading between 60 and 70 m , revealing that there is virtually no cement present in this interval.

  • e cement bond logs shown below

utilize acoustic data to determine the degree of cement bonding to the pipe and formation. Primary log presentations include pipe amplitude curves in Track 2 and a Micro- Seismogram® (MSG) waveform in Track 4.Amplitude curves are used in the calculation of percent of bond to the pipe while the MSG reveals qualitative information on both the pipe and formation bond.

  • is cement bond log shows a fully bonded section. Note the low amplitude signals in track 2

(approximately 1 mV) and the absence of pipe signals in Track 4 of the MSG. e volumetric map in Track 3 shows 100% solid material except for a small section in the middle, where it is approximately 70% to 75% bonded. Formation signals in the MSG waveform indicate cement bond to the formation.
