Abstract
Methods of stimulating subterranean formations are provided. More particularly, methods of fracturing subterranean formations using a fracturing fluid comprising a self-degrading cement composition are provided. An example of a method is a method of treating a subterranean formation. Another example of a method is a method of fracturing a subterranean formation. Another example of a method is a method of producing hydrocarbons from a subterranean formation.
Claims20
A method comprising:
- providing a fracture in a portion of a subterranean formation;
- placing a fluid in the fracture, the fluid comprising an acid source, a base source, a water source, and a degradable material;
- permitting the fluid to set within the fracture to form a solid mass;
- and
- permitting the degradable material to at least substantially degrade.
2 more elements
A method comprising:
- hydraulically fracturing a portion of the formation to create or enhance at least one fracture therein;
- placing a fluid in the at least one created or enhanced fracture, the fluid comprising an acid source, a base source, a water source, and a degradable material;
- permitting the fluid to set within the at least one created or enhanced fracture to form a solid mass;
- and
- permitting the degradable material to at least substantially degrade, after the fluid sets in the at least one created or enhanced fracture to form a solid mass, so as to create voids in the solid mass.
2 more elements
A method comprising:
- providing a fracture in a portion of a subterranean formation;
- placing a fluid in the fracture, the fluid comprising an acid source, a base source, a water source, and a degradable material, wherein
- the acid source comprises at least one acid source selected from the group consisting of magnesium chloride, potassium phosphate monobasic, ammonium phosphate monobasic, and phosphoric acid;
- permitting the fluid to set within the fracture to form a solid mass;
- and
- permitting the degradable material to at least substantially degrade.
