Mixture for pre-cementing operation in wellbore
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 pre-cementing operations with respect to the wellbore.
1. A method comprising:
preparing a wellbore fluid, the wellbore fluid including a base fluid, a crushed glass material, a biopolymer viscosifier that includes at least one of diutan gum or welan gum, and an alkali activator, wherein the crushed glass material comprises soda-lime glass particles;
positioning the wellbore fluid in a wellbore;
activating the alkali activator to interact with the wellbore fluid to form a plugging matrix in one or more lost circulation zones of the wellbore; and
performing a pre-cementing operation comprising a lost circulation operation with respect to the wellbore using the wellbore fluid, wherein the plugging matrix is retained in the one or more lost circulation zones.
2. The method of claim 1 , wherein the crushed glass material comprises recycled glass material, and wherein the base fluid comprises water.
3. The method of claim 1 , wherein the crushed glass material includes particles within a predetermined size-range.
4. The method of claim 3 , wherein performing the pre-cementing operation includes performing the lost circulation operation in the wellbore using the particles of the crushed glass material within the predetermined size-range.
5. The method of claim 4 , wherein positioning the wellbore fluid in the wellbore includes batch-mixing the crushed glass material with the base fluid prior to positioning the wellbore fluid in the wellbore.
6. The method of claim 1 , further comprising:
identifying a plurality of perforations located in the wellbore, the plurality of perforations including a size range of perforations included in the plurality of perforations; and
selecting, based on the size range of perforations included in the plurality of perforations, a plurality of particle sizes for the crushed glass material.
7. The method of claim 6 , wherein:
identifying the plurality of perforations comprises identifying a first perforation located in a first location of the wellbore and identifying a second perforation located in a second location of the wellbore;
the first perforation has a first size and the second perforation has a second size; and
the second size is different than the first size and the second location is different than the first location.
8. The method of claim 7 , wherein selecting the plurality of particle sizes for the crushed glass material comprises:
selecting a first size of crushed glass material, wherein the first size of crushed glass material corresponds to the first size of the first perforation; and
selecting a second size of crushed glass material, wherein the second size of crushed glass material corresponds to the second size of the second perforation.
