... liner, created by poor casing centricity. Data acquired with new transducer showed moderate to good cement quality across majority of the 7.25-inch liner, despite suspected liner eccentricity. Poor cement quality confirmed near the liner shoe. Along with ultrasonic pulse-echo measurements...

... and water saturation. Analysis in these wells is performed not only to evaluate cement quality, but also to relate it to casing centricity with respect to formation or outer casing walls to help reaching objectives for cementing jobs in future wells. Cement evaluation with wireline tools is one...
