Abstract
The present invention relates to well bore operations, and more particularly, to contained micro-particles, and methods for using such contained micro-particles in cementing operations. An exemplary method of facilitating the use of micro-particles in a well bore fluid comprises the steps of providing contained micro-particles, and adding the contained micro-particles to the well bore fluid. In an exemplary embodiment, the well bore fluids of the present invention comprise encapsulated micro-particles. In another exemplary embodiment, the well bore fluids of the present invention comprise pelletized micro-particles.
Claims54
A method of cementing in a subterranean formation comprising the steps of:
- providing a cement composition, wherein at least one component of the cement composition comprises micro-particles that were added to the cement composition as encapsulated micro-particles;
- placing the cement composition into the subterranean formation;
- and
- allowing the cement composition to set.
A method of cementing in a subterranean formation comprising the steps of:
- providing a cement composition wherein the cement composition comprises:
- cement and micro-particle silica, wherein at least a portion of the micro-particle silica was added to the cement composition as encapsulated micro-particle silica;
- placing the cement composition into the subterranean formation;
- and
- allowing the cement composition to set.
A method of cementing in a subterranean formation comprising the steps of:
- providing a cement composition wherein the cement composition comprises:
- cement and crystalline micro-particle silica, wherein at least a portion of the crystalline micro-particle silica was added to the cement composition as encapsulated crystalline micro-particle silica;
- placing the cement composition into the subterranean formation;
- and
- allowing the cement composition to set.
A method of cementing in a subterranean formation comprising:
- providing a cement composition, wherein at least one component of the cement composition comprises encapsulated micro-particles;
- placing the cement composition into the subterranean formation;
- and
- allowing the cement composition to set.
