The present invention relates to subterranean cementing operations, and more particularly, to methods of cementing in subterranean formations using cement compositions that autogenously cure voids that may form in such cement compositions. Methods of use of the fluids are also disclosed. A second cavitation bubble is created within the second outlet channel to block fluid flow out of the second outlet channel. The front face may include a number of configurations such as, but not limited to, an angled surface, a concave surface, and others. A deep security manager and deep security agent, at the customer site, collect local confidence attributes that are used for determining the local confidence score.
