Qualitative interpretation of the cement-to-formation interface. This amplitude is maximum in unsupported pipe Bond index. These amplitudes are a function of drilling mud, cement acoustic properties, casing size and thickness • Quick basics of purposes of cement & scenarios bond logs run in How traditional acoustic bond logs work and what is measured and presented Amplitude Travel Time Variable Density Log (VDL) Examples of good cement bond and free pipe and what things to look for Channeling – why run a radial investigation log PART VLOG INTERPRETATION Do not rely on the service company charts for amplitudes corresponding to a good bond. Tool response depends on the acoustic impedance of the cement, which, in turn is function of density and velocity. All Section Staff Montana Operations Office. These amplitudes depend on many factors: type of cement used, fluid in the hole, etc. On the basis of empirical data, the log can be calibrated directly in terms of cement compressive strength The interpretation of the CBL cement bond log response with bond index requires correct knowledge of the amplitude of % cemented sheath and of free pipe used in the cementing operations. However, despite the technical advances, the perceived accuracy of the CBL as a diagnostic tool has remained Interpretation products have moved from consulting a nomograph to colourful displays that provide clearer representations of anticipated cement placement in the annulus. Tom Pike, Chief UIC Direct Implementation Section. • Quick basics of purposes of cement & scenarios bond logs run in How traditional acoustic bond logs work and what is measured and presented Amplitude Travel Time Cement Bond Log Quick Reference BrooksRed DeerWhitecourtGrande PrairieCased Hole Logging TCP and logging techniques and interpretation. These procedures are to be followed when Cement bond log tools (CBLs) have evolved over the years as technology and telecommunications have advanced. To estimate bond index, choose intervals on the log that correspond to 0% bond and % bond reliability and signal to noise capability. From the s basic single transmitter and dual The Cement Bond Log (CBL) gives a continous measurement of the amplitude of sound pulses from a transmitter to receiver.
