Abstract
Improved well fluids that include hollow particles, and methods of using such improved well fluids in subterranean cementing operations are provided. Also provided are methods of cementing, methods of reducing annular pressure, and well fluid compositions. While the compositions and methods of the present invention are useful in a variety of subterranean applications, they may be particularly useful in deepwater offshore cementing operations.
Claims20
A method of affecting annular pressure buildup in an annulus in a subterranean formation comprising placing within the annulus a well fluid comprising a base fluid and hollow particles, wherein at least a portion of the hollow particles collapse or reduce in volume so as to affect the annular pressure.
