The WOS Radial Bond Log tool provides proven superior responsiveness and reliability 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 assess hydraulic isolation between producing and non-producing zones, a critical factor needed to assess well integrity.
In addition to standard cement bond amplitude (CBL) through near receiver (3-ft) and variable density log (VDL) through far receiver (5-ft), the RBL tool provides a cement map through eight receivers (Radial @2Ft ). Each segment covers a 45° section of the pipe which gives a complete 360° evaluation of bond integrity.
