A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant () and proppant-spacing filler material () through a wellbore () into the fracture (), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands () spaced apart by the material (), and removing the filler material () to form open channels () around the pillars (). The filler material can be dissolvable particles, initially acting as a consolidator during placement of the proppant in the fracture, and later dissolving to leave flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Heterogeneous proppant placement in a fracture with removable extrametrical material fill

A method of injecting well treatment fluid including proppant and proppant-spacing filler material through a wellbore into the fracture, heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands spaced apart by the material, and removing the filler material to form open channels around the pillars for fluid flow from the formation through the fracture toward the wellbore. The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The filler material can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and/or to inhibit settling of the proppant.

This invention relates to petroleum industry, in particularly, to control and monitoring of processes related to reservoir stimulation. A method of real time diagnostic of fracture operations with combination of tube waves and microseismic monitoring, comprising performing a fracture in a wellbore, recording microseismic activity generated during the fracturing operations. Determining of microseismic event locations, generating low frequency pressure waves (tube waves) near the wellbore, recording of tube waves reflections from the fractures in real time and analyzing microseismic event locations and tube waves reflections from the fractures.
