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.

Claims (29)

1 . 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.

2 . The treatment fluid of claim 1 , wherein the particles included in the first subset and the second subset have a hardness and angularity to form the scouring agent in the wellbore.

3 . The treatment fluid of claim 1 , wherein the treatment fluid is positionable in the wellbore subsequent to being batch-mixed using the crushed, synthetic, recycled glass material, the base fluid, and the biopolymer viscosifier.

4 . The treatment fluid of claim 3 , wherein the pre-cementing operation in the wellbore includes a wellbore cleaning operation in which the treatment fluid is usable as a spacer to clean the wellbore prior to performing a cementing operation in the wellbore.

5 . The treatment fluid of claim 3 , wherein the treatment fluid is positionable in the wellbore while the crushed, synthetic, recycled glass material is being mixed with the base fluid and the biopolymer viscosifier.

6 . The treatment fluid of claim 1 , wherein the biopolymer viscosifier includes at least one of diutan gum or welan gum.

7 . A treatment fluid comprising:

a wellbore fluid comprising a biopolymer viscosifier;

an alkali activator dispersed in the wellbore fluid; and

a crushed, synthetic, recycled glass material dispersed in the wellbore 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.

8 . The treatment fluid of claim 7 , wherein the particles included in the first subset and the second subset have a hardness and angularity to form the scouring agent in the wellbore.

9 . The treatment fluid of claim 8 , wherein the plurality of particles of the crushed, synthetic, recycled glass material is usable to perform the lost circulation operation, and wherein the treatment fluid is positionable in the wellbore subsequent to the crushed, synthetic, recycled glass material being batch-mixed with the wellbore fluid.

10 . The treatment fluid of claim 7 , wherein the pre-cementing operation in the wellbore includes a wellbore cleaning operation in which the treatment fluid is usable as a spacer to clean the wellbore prior to performing a cementing operation in the wellbore, and wherein the treatment fluid is positionable in the wellbore while the crushed, synthetic, recycled glass material is being mixed with the wellbore fluid.

11 . The treatment fluid of claim 7 , wherein the plugging matrix is retainable in one or more lost circulation zones of the wellbore.

12 . The treatment fluid of claim 7 , wherein the biopolymer viscosifier includes at least one of diutan gum or welan gum.

13 . 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.

14 . The treatment fluid of claim 13 , wherein the crushed, synthetic, recycled glass material comprises soda-lime glass particles.

15 . The treatment fluid of claim 13 , wherein the particles included in the first subset and the second subset have a hardness and angularity to form the scouring agent in the wellbore.

16 . The treatment fluid of claim 15 , wherein the plurality of particles of the crushed, synthetic, recycled glass material is usable to perform the lost circulation operation, and wherein the treatment fluid is positionable in the wellbore subsequent to the crushed, synthetic, recycled glass material being batch-mixed with the base fluid.

17 . The treatment fluid of claim 13 , wherein the pre-cementing operation in the wellbore includes a wellbore cleaning operation in which the treatment fluid is usable as a spacer to clean the wellbore prior to performing a cementing operation in the wellbore, and wherein the treatment fluid is positionable in the wellbore while the crushed, synthetic, recycled glass material is being mixed with the base fluid.

18 . The treatment fluid of claim 13 , wherein the biopolymer viscosifier includes at least one of diutan gum or welan gum.
