... of the data will reduce well cost by avoiding unnecessary operational measures (squeeze jobs, sidetracks) or hardware additions (tie- back packers) and by confirming well integrity. The authors will present case studies in which a combination of cement bond log and variable density log (CBL-VDL) logs together...

... are somewhat different. For the Cement Bond Log a short spacing is desired in order to show more clearly the attenuation rate of the casing arrival. For the VDL a longer spacing is desired in order to show the formation arrivals in well bonded intervals. To satisfy these differing requirements, a two-receiver...
