The Radial Bond Log Tool (RBT)
The Radial Bond log Tool (RBT) provides proven superior reliability and responsiveness even in thin cement sheath conditions. With circumferential cement bond evaluation, the RBL identifies channels, in addition to standard cement bond logging. The main application of the Radial Bond Log Tool is to evaluate hydraulic isolation between producing and non-producing zones– a key factor needed to assess the integrity of the well.
The RBT features a powerful sonic transmitter and an array of radially segmented acoustic sensors that derive a calibrated amplitude measurement of the induced sonic signals as they propagate along the length of the casing or liner. These segmented measurements enable the identification of small axial channels. In addition, the tool provides the traditional 3 / amplitude and 5 ft. VDL measurements to provide comprehensive evaluation of cement to casing and cement to formation bonding.
