Abstract
Zeolite compositions having enhanced compressive strength and methods therefor are provided. In particular, methods and compositions for wellbore treating fluids, especially settable spotting fluids having enhanced compressive strength are provided.
Claims7
A method of performing drilling operations comprising:
- penetrating a subterranean zone with a wellbore;
- introducing a wellbore treating fluid into the wellbore, the fluid comprising a blended composition comprising zeolite having a mean particle size less than or equal to 100 microns, an organic acid or salt thereof in an amount of greater than or equal to 0.1% and less than or equal to 5.0% by weight of zeolite, and a carrier fluid;
- introducing a subsequent composition into the wellbore, the subsequent composition comprising an activator in an amount of greater than or equal to 5% and less than or equal to 50% by weight of the zeolite/activator composition, to displace all but a remaining portion of the wellbore treating fluid from the wellbore;
- and
- contacting the blended composition in the remaining portion of the wellbore treating fluid with the subsequent composition to form a set composition.
