Abstract

A method may include: providing a spacer fluid comprising water and an agglomerated zeolite catalyst; and displacing a drilling fluid in a wellbore using the spacer fluid. The agglomerated zeolite catalyst may be a spent agglomerated zeolite catalyst and may include a matrix, a filler, a binder, and zeolite crystals. The zeolite crystals may be selected from the group consisting of type x, type y, ultra-stable type y, ZSM-5, SAPO-11, silicalite-1, mordenite, ferrierite, beta, and combinations thereof.

First claim

What is claimed is:

1. A method comprising:
providing a spacer fluid comprising water and an agglomerated zeolite catalyst wherein the agglomerated zeolite catalyst comprises a matrix, a filler, a binder, and zeolite crystals; and
displacing a drilling fluid in a wellbore using the spacer fluid.

2. The method of claim 1 wherein the spacer fluid further comprises hydrated lime.

3. The method of claim 2 further comprising allowing the spacer fluid to consolidate in an annular space in the wellbore.

4. The method of claim 1 wherein the agglomerated zeolite catalyst is a spent agglomerated zeolite catalyst.

5. The method of claim 1 wherein the zeolite crystals are selected from the group consisting of type x, type y, ultra-stable type y, ZSM-5, SAPO-11, silicalite-1, mordenite, ferrierite, beta, and combinations thereof.

6. The method of claim 1 wherein the agglomerated zeolite catalyst is present in an amount of about 1% to about 80% by weight of the spacer fluid.

7. A method comprising:
introducing a spacer fluid comprising agglomerated zeolite catalyst, hydrated lime, and water into a wellbore annulus such that the spacer fluid displaces a drilling fluid in the wellbore annulus, the agglomerated zeolite catalyst comprises a matrix, a filler, a binder, and zeolite crystals; and
introducing a cement composition into the wellbore annulus after the spacer fluid,
wherein at least a portion of the spacer fluid consolidates in the wellbore annulus to form a hardened mass.

8. The method of claim 7 wherein the agglomerated zeolite catalyst is a spent agglomerated zeolite catalyst.

9. The method of claim 7 wherein an agglomerated zeolite catalyst to hydrated lime weight ratio is about 1:3 to about 1:5, and wherein the spacer fluid is free of additional components that hydraulically set in the presence of water and hydrated lime.

10. The method of claim 7 wherein the zeolite crystals are selected from the group consisting of type x, type y, ultra-stable type y, ZSM-5, SAPO-11, silicalite-1, mordenite, ferrierite, beta, and combinations thereof.

11. The method of claim 7 wherein the cement composition comprises water and a hydraulic cement selected from the group consisting of Portland cements, pozzolana cements, gypsum cements, alumina based cements, silica cements, and combinations thereof.

12. A composition comprising:
an agglomerated zeolite catalyst, wherein the agglomerated zeolite catalyst comprises a matrix, a filler, a binder, and zeolite crystals;
hydrated lime; and
water.

13. The composition of claim 12 wherein the agglomerated zeolite catalyst is a spent agglomerated zeolite catalyst.

14. The composition of claim 12 wherein the zeolite crystals are selected from the group consisting of type x, type y, ultra-stable type y, ZSM-5, SAPO-11, silicalite-1, mordenite, ferrierite, beta, or combinations thereof.

15. The composition of claim 14 wherein the matrix is an amorphous solid comprising kaolin filler and silica sol binder, wherein the filler is a clay, and wherein the binder is an aluminate compound.

16. The composition of claim 12 wherein an agglomerated zeolite catalyst to lime weight ratio is about 1:3 to about 1:5.

17. The composition of claim 16 wherein the composition is free of additional components which hydraulically set in the presence of water and hydrated lime.
