• 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 toolsproduce 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 WaveSonic 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. SuperiorWellsite Presentations Real-time results can be presented in a variety of formats to match specific wellsite operations. The wellsite engineer can switch between formats during logging for optimalviewing. The 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 anda MicroSeismogram® (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 formationbond.
