Radial Bond Log Tool (RBT)
Description
The 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 Wellscience well integrity tools. The tool is comprised of H2S resistant materials throughout. The RBT tool has a built-in orientation sensor that allows for relative bearing and deviation data.
