Abstract:
A method of propping created fractures and microfractures in tight formation. The method includes injecting into a wellbore a first pad fluid stage; injecting into the wellbore a second pad fluid stage; injecting into the wellbore a diverting agent; and injecting into the wellbore a main proppant slurry stage; wherein the first pad fluid stage includes an aqueous-based fluid at a rate above the fracturing gradient to create a fracture, wherein the second pad fluid stage includes an aqueous-based fluid and a low concentration of a proppant mixture including a slurry of small proppant materials and/or a slurry of conventional proppant materials to extend the fracture and open up secondary induced fractures, and wherein the main proppant slurry stage includes an aqueous-based fluid and a proppant with a larger size than the small proppant particles in the second pad fluid stage.

Claim (Index 13):
The method according to  claim 1 , wherein the proppant in the second pad fluid stage and the main proppant slurry stage are mixture of proppants with different specific gravities, crush strengths, and degradability, such that once injected into the fracture, the proppants can suspend, settle, form bridges, and/or pack, to ensure that the fracture remains open with high conductivity.
