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

Cement bond logs were run as early as 1958 with early sonic logs and the temperature log was used to find cement top beginning in 1933. Cement integrity logs are run to determine the quality of the cement bond to the production casing, and to evaluate cement fillup between the casing and the reservoir rock.
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 .
temperature survey or cement bond log well be required in the event that the cement is not circulated to the ground surface 4 Surface Casing Regulations Texas Railroad Commission District 10 Nov 2005 Maximum casing depth will not exceed 3500 ft Surface casing shall be set before drilling into known shallow oil and gas formations. Zone
CementBondLog Interpretation Reliability. Two kinds of cementbondlog (CBL) tools are run as part of a standard cementevaluation program. The effectiveness of these tools and their evaluations often are challenged, and they are not regarded as a replacement for reservoir interzonalcommunication tests performed between producing reservoirs.
Jul 03, 2017· The Cement Bond Logging tools have become the standard method of evaluating cement jobs. They indicate how good the cement bond is. A cement bond log (CBL) documents an evaluation of the integrity of cement job performed on an oil well. It .
A Cement Evalua tion (CET*) log from a well in a Middle East carbonate reservoir. The CET tool has eight ultrasonic transducers distributed radially on a mandrel. Emitted acoustic energy res onates the casing if there IS no cement bond and shows up as white on the image in track 3 of the log. A good bond shows up as black. The top third of the
A log that uses the variations in amplitude of an acoustic signal traveling down the casing wall between a transmitter and receiver to determine the quality of cement bond on the exterior casing wall. The fundamental principle is that the acoustic signal will be more attenuated in the presence of cement than if the casing were uncemented.

Feb 17, 2016· A cement bond log (CBL) is a type of log that measures the loss of acoustic energy as it passes through casing. A cement bond log documents an evaluation of the integrity of cement work performed on an oil well. In the process of drilling and completing a well, cement is injected through the wellbore and rises up the annulus between the steel ...

Comparison of the full waveform to logs that are sensitive to porosity/lithology can help to evaluate the cement bond log. Caliper information from the open hole is important. Knowledge of the well mechanics and facts about, as well as conditions during, the cement job is extremely important in evaluating the measurements from cement bond logs.
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 industrystandard sonic tools are usually displayed on a cement bond log (CBL) in millivolt units, decibel attenuation, or both.
