Zone
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.

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).
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
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
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.
• 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
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]
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 ...
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 .
