Abstract
A treatment fluid for performing one or more pre-cementing operations in a wellbore can include a base fluid, a viscosifier, and a crushed glass material. The viscosifier can be dispersed in the base fluid. The crushed glass material can be dispersed in the base fluid for performing one or more cementing operations with respect to the wellbore.
Claims18
A treatment fluid comprising:
- a base fluid;
- a biopolymer viscosifier dispersed in the base fluid;
- an alkali activator dispersed in the base fluid;
- and
- a crushed, synthetic, recycled glass material dispersed in the base fluid for performing a pre-cementing operation in a wellbore, wherein the crushed, synthetic, recycled glass material comprises soda-lime glass particles, wherein the pre-cementing operation comprises a lost circulation operation, wherein the crushed, synthetic, recycled glass material includes a plurality of particles, wherein a first subset of the plurality of particles has a first predetermined size range and a second subset of the plurality of particles has a second predetermined size range that is different than the first predetermined size range, wherein the alkali activator comprises material to hydrate over time to form a plugging matrix, and wherein the first subset and the second subset include particles that are combinable to form a scouring agent.

A treatment fluid comprising:
- a base fluid;
- a biopolymer viscosifier dispersed in the base fluid;
- an alkali activator dispersed in the base fluid, the alkali activator activatable to form a plugging matrix;
- and
- a crushed, synthetic, recycled glass material dispersed in the base fluid for performing a pre-cementing operation in a wellbore, wherein the plugging matrix is retainable in one or more lost circulation zones of the wellbore during a pre-cementing operation that comprises a lost circulation operation, wherein the crushed, synthetic, recycled glass material includes a plurality of particles, wherein a first subset of the plurality of particles has a first predetermined size range and a second subset of the plurality of particles has a second predetermined size range that is different than the first predetermined size range, wherein the alkali activator comprises material to hydrate over time to form a plugging matrix, and wherein the first subset and the second subset include particles that are combinable to form a scouring agent.
