COMPOSITIONS AND METHODS FOR SERVICING SUBTERRANEAN WELLS
First Claim
1. A method for stimulating a subterranean formation penetrated by a wellbore, comprising:
- injecting into the wellbore a well-treatment fluid at a rate and pressure sufficient to create and propagate a fracture in the formation, wherein the treatment fluid comprises a first slurry comprising;
(a) at least one inorganic cement;
(b) water; and
(c) at least one disruptive agent.

Abstract
Subterreanean formations penetrated by a wellbore may be stimulated by injecting a well-treatment fluid at a rate and pressure sufficient to create and propagate a fracture in the formation. The treatment fluid comprises a first slurry comprising at least one inorganic cement, water and at least one disruptive agent that may cause the formation of open channels in the fracture through which hydrocarbons in the formation may flow into the wellbore. The disruptive agent may comprise (but would not be limited to) water-soluble polymers that cause flocculation and agglomeration of cement solids, expansive agents, explosive agents, degradable materials, or a combination thereof.
