Detection of internal and exter- nal damage or deformation. Casing thickness analysis for collapse and burst pressure calculations. Measurement Specifications.
Acoustic impedance, cement bonding to casing, internal radius, casing thickness. Trouble with Linux virtual machines.
Unfortunately we are seeing some issues with some of our Linux VMs. We are hard at work looking for the root cause of the issue. Active colossus jobs will not be affected. We will post information about progress on the 28th on the operational log. Apologies for the inconvenience.

The UBI is an openhole tool for. What to look for in a USIT log. Table of Contents Common formats Cement evaluation examples. USIT Image Interpretation and guide Other Effects . Readings on USIT radius and thickness measurements . I would want to know the difference of the data being recorded by CBL-VDL over USIT. Do they run all three logs.
USIT stands for Ultrasonic Imaging Tool (cement bond logging ). USIT is defined as Ultrasonic Imaging Tool (cement bond logging ) very rarely. Acoustic cement bond logs do not measure hydraulic seal but instead measure loss of acoustic energy as it propagates through casing. This loss of energy is related to the fraction of casing perimeter covered by cement.

Third Interface imaging . Light-density cement evaluation. Ultrasonic radial-cement-evaluation devices and modified openhole-imaging devices are also used to evaluate casing . Acoustic logs do not measure cement quality directly, rather, this value is inferred from the degree of acoustic coupling of the cement to the casing and to the formation. Properly run and interprete cement-bond logs (CBL) provide highly reliable estimates of well integrity and zone isolation. AVAILABLE IN LOG HOME BOOKSTORE .
