ABSTRACT:
Cement bonding and bond logs in wells are significantly improved by imparting random or periodic, pulsating, oscillating or vibrating pressure to the fluids present during all stages of a cementing operation. The effect is to eliminate gelation of the fluids to improve cement placement and to enable consolidation of the cement slurry. The pressure pulses can also be detected to monitor the condition of the setting slurry.
