The Cement Bond Log (CBL) gives a continous measurement of the amplitude of sound pulses from a transmitter to receiver. This amplitude is maximum in unsupported pipe and minimum in .
1.2 BASIC LOG TYPES Below is a list of the main types of logs that may be run, and why they are run. 1.2.1 Logging While Drilling (LWD) Traditionally, petrophysicists were concerned only with wireline logging, that is, the data acquired by running tools on a cable from a winch after the hole had been drilled. However, advances in drilling/logging
Cement-Bond-Log Interpretation Reliability. Two kinds of cement-bond-log (CBL) tools are run as part of a standard cement-evaluation program. The effectiveness of these tools and their evaluations often are challenged, and they are not regarded as a replacement for reservoir interzonal-communication tests performed between producing reservoirs.
The SCBT evaluates the cement bond quality and integrity to both pipe and formation by providing the measurements of the cement bond amplitude (CBL) through the near receiver (3-ft crystal), and variable density log (VDL) through the far receiver (5-ft Crystal).
May 22, 2010· On the other hand, BP has been criticized – as in the linked article – for not running a Schlumberger cement bond log to evaluate the condition of the cement. I'm no deepwater drilling expert, but I would have found it a little unusual for them to .

Oct 15, 2009· Acoustic energy is absorbed when cement is in contact with the casing and formation. CEMENT BOND LOG INTERPRETATION: In general terms, A high signal amplitude indicates poor cement bond. A low signal amplitude indicates good cement bond. Amplitude is normally presented on a scale of 0 to 100 percent amplitude.

CEMENT DESIGN IMPACTS ON LOG RESPONSE The closer the cement density is to that of the drilling fluid used, the more difficult it is to distinguish between a solid & a liquid The lower the compressive strength of the cement, the more difficult it is to "find" on a log, and requires use of specialty tools and evaluation software
A cement bond log (CBL) must be submitted showing adequate cement isolation above the perforations. The casing must be pressure tested before perforating (or with a bridge plug if already perforated). An RTS with a time-drive supplement may be run. Oil-based fluids are not authorized.

Cement bond tools measure the bond between casing and the cement placed in the annulus between the casing and the wellbore. The measurement is made by using acoustic sonic and ultrasonic tools. The measurements of industry-standard sonic tools are usually displayed on a cement bond log (CBL) in millivolt units, decibel attenuation, or both.
The surveys included in this group are: Gamma Ray Neutron Temperature Pulsed Neutron Cement Bond Log Some of these surveys like the gamma ray, neutron and temperature logs can be run in both open and cased hole wells.
