  • Publication number: 20230406765
    Abstract: A cement composition can include water and a blended cement. The cement composition can be free of Portland cement. The blended cement can include cement and a supplementary cementitious material. The cement can be calcium aluminate cement or calcium aluminophosphate cement. Fly ash is a common supplementary cementitious material containing silica. However, fly ash can have large variances depending on the source of the fly ash. Instead of fly ash, the supplementary cementitious material can be ground synthetic glass, such as soda-lime glass, which has consistent properties regardless of the source.

  • Patent number: 11480025
    Abstract: Methods, compositions, and tools for use in creating rapidly forming plugs in situ in subterranean formations. In one instance, the disclosure provides a method that includes: placing a first pill comprising a calcium-aluminate-based cement composition at a plug location within the wellbore with the tubing; and placing a second pill comprising an alkaline fluid composition into the wellbore adjacent to the first pill with the tubing. In some cases there is a spacer fluid or spacer device between the first pill and the second pill. In some cases tubing having a mixing device is located at the bottom of the tubing in the wellbore to aid I mixing the first pill and the second pill to facilitate a chemical in situ reaction of the first pill and the second pill. The reaction between the first pill and the second pill forms a set plug at the plug location.
