A major oil and gas operator in North America required a more detailed evaluation of its lightweight zonal isolation job after the initial cement bond log (CBL) data yielded inconclusive results. The operator had used a low-density resin material in its Permian Basin well to help minimize lost circulation and achieve the specified top of cement, but the resin additive—which increased the shear bond strength between the casing and the annular material—also reduced the slurry weight to only 9.4 ppg. The low-density cement made evaluation difficult using conventional acoustic-based technologies, and the 7-in. casing had an Inconel coating on the inside of the pipe which also compromised the measurements.
