CITM Casing Inspection Tool

CITM – Coming Soon!

Casing Inspection Thickness Measurement

CBG-5

We are currently redesigning the original version of the CITM to better accommodate the Water Well Industry. The original CITM required the use additional, and more expensive, tools designed for the Oil & Gas industry. It also required the knowledge and use of a surface system called the Warrior Logging System, often unknown to those outside of the O&G industry. The newer version CITM will provide the same measurements at a greatly reduced price and be considerably easier to manage in the field. We expect the CITM-B to be in field-test in the U.S. by the end of 2020.

The CITM tool is used for inspecting large water well casings from 12” to 30” diameter. Based on our Induction Collar Locator (ICL), it is the only water well casing inspection tool capable of simultaneously measuring Casing Weight, Internal Casing Diameter, Collars, Centralizers, Perforations, Internal/External Corrosion, Internal Pipe Pressure and Fluid Temperature. During the casing inspection procedure, the tool provides information on casing irregularities often missed by video surveys.

The tool uses oscillating magnetic fields to set up and measure Remote Field Eddy Currents in the casing via a combination of transmitter and receiver coils at two separate frequency ranges. For casing inspection, the phase shift is measured between a transmitter and receiver coil, operating at low frequencies of 10-30 Hz. A differential phase measurement between the two receiver coils provides a highly resolved view of the casing wall thickness.

A high frequency signal of 50-100KHz is used to provide an amplitude measurement between the transmitted and received signal which provides the internal casing diameter or caliper. The casing outside diameter can then be calculated using the wall thickness and ID measured values, providing a sectional view of the casing.

Additional Features

  • Diagnostics – Tool status measurements such as current and voltage.
  • Diagnostics – Tool status measurements such as current and voltage.
  • Calibration – Store customer calibration data across a range of pipe sizes.
  • Real Time Data – Interface with standard telemetry systems to send real time data to and receive commands from a surface logging system.
  • Memory Logging – Data record to memory at a predefined interval for post run analysis.
