Abstract
Disclosed embodiments relate to well treatment fluids and methods that utilize nano-particles. Exemplary nano-particles are selected from the group consisting of particulate nano-silica, nano-alumina, nano-zinc oxide, nano-boron, nano-iron oxide, and combinations thereof. Embodiments also relate to methods of cementing that include the use of nano-particles. An exemplary method of cementing comprises introducing a cement composition into a subterranean formation, wherein the cement composition comprises cement, water and a particulate nano-silica. Embodiments also relate to use of nano-particles in drilling fluids, completion fluids, simulation fluids, and well clean-up fluids.
Claims21
A method of treating a subterranean formation comprising:
- introducing into the subterranean formation a treatment fluid at or above a pressure sufficient to create or enhance one or more fractures in the subterranean formation wherein at least a portion of the treatment fluid contains a proppant comprising nano-particulates;
- and
- depositing at least a portion of the nano-particulates in the one or more fractures, wherein the fractures are prevented from fully closing upon the release of pressure.
A fracturing fluid comprising a nano-sized proppant.
A method of treating a subterranean formation comprising:
- introducing into the subterranean formation a treatment fluid comprising particulate materials, the particulate materials comprising a particulate having a particle size of less than or equal to about 100 nm;
- and
- determining a packing volume fraction for the particulate materials in the treatment fluid.
