Abstract
Wellbore fluids comprising an expanded and ground perlite and methods of using the same are disclosed. In one embodiment, the methods include a method of cementing comprising preparing or placing a cement composition comprising cement, water, and an expanded and ground perlite. The method further comprises allowing the cement composition to set. A method of servicing a wellbore, comprising providing a wellbore fluid comprising a base fluid and an expanded and ground perlite, placing the wellbore fluid into an annulus in the wellbore, placing a cement composition into the annulus, and allowing the cement composition to set.

A method of servicing a wellbore, comprising:
- providing a spacer fluid comprising a base fluid and an expanded and ground perlite, wherein the expanded and ground perlite was expanded prior to being ground;
- placing the spacer fluid into an annulus in the wellbore;
- placing a cement composition into the annulus to displace the spacer fluid that has been placed into the annulus;
- and
- allowing the cement composition to set.
A method of servicing a wellbore, comprising:
- circulating a drilling fluid in an annulus in the well bore;
- providing a spacer fluid comprising a base fluid and an expanded and ground perlite, wherein the expanded and ground perlite was expanded prior to being ground;
- placing the spacer fluid into the annulus in the wellbore;
- placing a cement composition into the annulus to displace the spacer fluid that has been placed into the annulus;
- and
- allowing the cement composition to set.
A method of servicing a wellbore, comprising:
- providing a spacer fluid comprising a base fluid and an expanded and ground perlite, wherein the expanded and ground perlite was expanded prior to being ground, wherein the expanded and ground perlite is present in the spacer fluid in an amount of about 10% to about 25% by weight of the spacer fluid, wherein the expanded and ground perlite has a mean particle size from about 10 microns to about 120 microns;
- placing the spacer fluid into an annulus in the wellbore;
- placing a cement composition into the annulus to displace the spacer fluid that has been placed into the annulus;
- and
- allowing the cement composition to set.
