Abstract: Methods and systems for enhancing acid fracture conductivity of acid fracture treatments on subterranean formations are provided. An example method of acid fracture treatment includes initiating fracturing of a subterranean formation in which a wellbore is formed to create a formation fracture, after initiating the fracturing for a period of time, injecting an acidic fluid into the wellbore to etch walls of the formation fracture to thereby create fracture conductivity, introducing a gas into the wellbore to foam fluids in the wellbore, and increasing a foam quality of the fluids with time during the treatment. The foam quality is based on a volume of the introduced gas and a total volume of the fluids in the wellbore.

Abstract: The complexity of a fracture network within a subterranean formation may be enhanced by pumping a high breakdown pressure fluid followed by a low breakdown pressure fluid into the formation. The method increases the Stimulated Reservoir Volume (SRV) of the formation and provides for a network of ancillary fractures within the formation.

Abstract: Provided herein are compositions and methods for treating wells in geologic formations. The method involves introducing a first aqueous composition containing an organic acid into a well, introducing a second aqueous composition into the well, and forming a third composition useful for stimulating wells, fracturing geologic formations, and cleaning wells of filter cakes and other well blockages.

Abstract: A method for extracting natural gas or petroleum-based products, including: introducing shape memory alloy beads into a wellbore with hydraulic fracturing fluid to form a bridge comprising shape memory alloy beads in a tertiary path, where the shape memory alloy beads forming the bridge have a first phase, and the hydraulic fracturing fluid has an initial hydraulic fracturing fluid flow rate across the bridge; applying a pressure to transform the shape memory alloy beads to a second phase, where deforming the shape memory alloy beads causes the hydraulic fracturing fluid to have a second hydraulic fracturing fluid flow rate across the bridge.

Abstract: Fracturing a reservoir includes providing a pad fluid to the reservoir via a wellbore in a well to create fractures in the reservoir, providing a fracturing fluid to the fractures via the wellbore, providing a geopolymer precursor fluid to the fractures via the wellbore, shutting in the wellbore at a wellbore pressure, thereby allowing the geopolymer precursor fluid to harden and form geopolymer proppant pillars in the fractures. Providing the geopolymer precursor fluid to the fractures includes pulsing quantities of the geopolymer precursor fluid into a continuous flow of the fracturing fluid or alternately pulsing quantities of the geopolymer precursor fluid and the fracturing fluid. An elapsed time between pulsing the quantities of the geopolymer precursor fluid is between 2 seconds and 20 minutes.

Abstract: A method of enhancing conductivity within a hydrocarbon-bearing reservoir by building proppant pillars in a spatial arrangement in fractures created or enlarged in the reservoir. Two fluids of differing stability are simultaneously pumped into the reservoir. The fluids may contain identical proppant mixtures which include a first proppant which has an apparent specific gravity less than the apparent specific gravity of a second proppant. The fluids may contain identical proppants mixtures where the average particle size of a first proppant is greater than the average particle size of a second proppant. Vertically extending pillars are created within the formation when the fluids are destabilized and the first proppant is then released from the destabilized fluids. The area between the pillars may be held open by the presence of the second proppant in the remaining fluid.

Abstract: Materials and methods for generating isolated pillar structures and conductive channels within hydrofracturing reservoirs are provided herein.

Abstract: The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a divert system comprising dissolvable diverter particulates and proppant. At least a portion of the high permeability zone is propped open with the proppant of the divert system and at least a portion of the high permeability zone is blocked with the diverter particulates. A fluid is pumped into the formation and into a lower permeability zone farther from the wellbore. The diverter particulates in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The divert system has particular applicability in the enhancement of production of hydrocarbons from high permeability zones in a fracture network located far field from the wellbore.
