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 ...

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.
• No cement bond log was run • 9:30 PM : The well begins to kick The Blow Out • 9:08 Pumps off, but well pressure kept rising • Mud was being pumped overboard into the Damon Bankston so they could not keep track of fluid volume changes • 9:40 Mud begins to flow onto the rig floor
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 .
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.
BASIC LOG TYPES Below is a list of the main types of logs that may be run, and why they are run. 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
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 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.
Non Hazardous Materials Examples Salt saturated or high chloride contaminated soils or semi solid material derived from oil/gas industry, underground cavern storage facilities, salt solution mined facilities, pipeline facilities, etc. Formation cuttings, muds, excess cement slurry from Class I, II, III, V, VI, oil and gas wells, and underground ...
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 (3ft crystal), and variable density log (VDL) through the far receiver (5ft Crystal).
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.

A cement bond log cannot be required as an external MIT under any circumstances, not even under RegFix''s 40 CFR §(f); cement bond logging is not a legal external or Part II MIT. Interestingly, at least EPA Region V seems to recognize that cement bond .

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.
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 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 timedrive supplement may be run. Oilbased fluids are not authorized.

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
