Overview


The Radial Bond Tool (RBT) is equipped with one transmitter and two receivers constructed of piezoelectric crystals. The near receiver, located 3ft from the transmitter, is constructed of an 8-sector radial receiver. Each sector provides bond data covering a 45 degree section of casing. The primary amplitude is constructed from radial signals at the near receiver. The far receiver, located 5ft from the transmitter, generates a Variable Density Log. The RBT deploys in deviated holes and combines readily with any of the complete range of tools. Its slotted sleeve technology provides sound isolation, rigidity and tool strength. The tool is comprised of corrosion resistant materials throughout.

Benefits

· To provide quantitative analysis of cement bond in eight 45 degrees segments for 360 degrees coverage across the borehole
· To effectively identify intervals of uniform bonding and detect cement channels or voids in casing sizes ranging from 4.5″ to 13.4″
· Quantitative analysis of cement bond to casing
· Quantitative analysis of cement bond to formation
· H2S resistant
