Abstract
Proppant compositions for hydraulic fracturing that include Portland cement clinker are provided. A cement clinker proppant composition for hydraulic fracturing may include Portland cement clinker and another proppant. Another cement clinker proppant composition for hydraulic fracturing may include resin-coated Portland cement clinker and another proppant. Methods of hydraulic fracturing using the cement clinker proppant compositions and manufacturing the cement clinker proppant compositions are also provided.
Claims8
A method of manufacturing a proppant composition for use in hydraulic fracturing a subterranean formation, the method comprising:
- heating Portland cement clinker in a mixer to a temperature of at least 370° F.;
- adding a resin to the Portland cement clinker to form a clinker-resin mixture;
- mixing the clinker-resin mixture for a mixing time period;
- adding a curing agent to the clinker-resin mixture;
- and
- curing the resin for a curing time period to produce resin-coated Portland cement clinker;
- and
- mixing the resin-coated Portland cement clinker with a proppant selected from the group consisting of a frac sand, a bauxite proppant, a ceramic proppant, and a polymer proppant,
- wherein the Portland cement clinker is dissolved by an acid to create conductivity pathways in a plurality of fractures in the subterranean formation.
