RADIAL BOND TOOL

The Radial Bond Tool (RBT) is equipped with one transmitter and two receivers constructed out of piezoelectric crystals. The near receiver, located 3Ft from the transmitter, is constructed of an 8-sector radial sensor.  The primary amplitude is constructed from radial signals at the near receiver while the Variable Density Log is constructed from the far receiver. The RBT can be deployed in deviated holes and combines easily with any of the other range of tools. 

 

 

The analog waveform is completely digitized downhole and converted back to analog at surface for interpretation. By digitizing downhole the tool is able to:

  • By-pass analog calibration pulse issues on H2S line transmission

  • Store and revert to a calibrated configuration upon power up. Internal memory settings for sensor pickups circumvent the need for free pipe calibration
