... Abstract Recent changes in guidelines for isolation of potential flow zones during well construction present new challenges for cement bond logging (CBL) tools. One challenge is cement evaluation logging in large thickwalled casing, i.e., casing with an outside diameter (OD) of 14 in or larger...
