Casing and cement bond logs Ahmed, A.E., 1977, A neutron logging method for locating the top of cement behind borehole casing: Journal of Petroleum Technology, v. 29, no. 9, p. 1089-1090.
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 .
Apr 11, 2019· The setting time depends on the type of cement, temperature, pressure, and the use of setting accelerants. Excess pressure on the casing should be avoided during the curing period so that the cement bond to the pipe is not disturbed. A cement bond log documents has an evaluation of the integrity of cement work performed on an oil well.[1]
A cement bond log (CBL) is a type of log that. measures the loss of acoustic energy as it. passes through casing. CEMENT BOND LOG (CBL) What is it used for? Cement bond logs are used to detect the. presence or absence of external cement. ... LOGGING REQUIREMENTS Last modified by: ladnr
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.
ESRA seminar, 5th of March 2009 ... Consider to verify the cement behind the production casing/liner with a cement bond log. 7) The minimum horizontal stress should be higher than the initial pore pressure. 8) The static BHP should exceed the collapse pressure of the formation. ...

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. ATTACHMENTS (SLIDE NOS. 27-35) $252 NON-REFUNDABLE ...
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.

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
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 .
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 ...

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).
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 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.
Introduction to cement bond logs FEBRUARY FACT SHEET 2017 Cement bond log tools (CBLs) have evolved over the years as technology and telecommunications have advanced. From the 1950s basic single transmitter and dual receiver design with analog communication and zero reprocessing capability, industry has moved to broadband transmitters
