  • Patent number: 10370950
    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.

  • Patent number: 10280737
    Abstract: Carbon quantum dots are used as tracers during the production of hydrocarbons. The tracer may be used to identify fluids produced from the reservoir. When used in the fracturing of multiple zones of the reservoir, qualitatively distinguishable carbon quantum dots may be used to identify the zone within the reservoir from which recovered fluid was produced. The carbon quantum dots may also be used in water flooding to determine water breakthrough in the production well. Upon water breakthrough in a production well, they may also be used to identify those injection wells from which breakthrough water originates.

  • Patent number: 10240447
    Abstract: A method of distributing proppant in a spatial arrangement throughout a created or enlarged fracture by pumping into a subterranean formation penetrated by a well multiple stages of fracturing fluid wherein a fluid laden with proppant is pumped into the well and a fluid substantially free of proppant is then pumped into the well; the fluid of the fluid laden with proppant and the fluid substantially free of proppant being the same. Vertically extending pillars are created within the formation. Fluid produced from the hydrocarbon-bearing reservoir is then flowed at least partially through channels between the vertically extending pillars.

  • Publication number: 20190040312
    Abstract: Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. In addition, the non-spherical particulates exhibit higher conductivity at higher stresses than spherical shaped particulates.

  • Patent number: 10161223
    Abstract: A method of hydraulically fracturing a subterranean formation penetrated by a wellbore comprises: providing a diverting fluid comprising a carrier fluid, a first superabsorbent polymer and a second superabsorbent polymer, the second superabsorbent polymer having a shape, or a composition, or a combination thereof different from that of the first superabsorbent polymer; injecting the diverting fluid into the subterranean formation; and injecting a fracturing fluid into the formation after injecting the diverting fluid. A viscosity modifying agent can be present in the diverting fluid. Superabsorbent polymers can also be used to develop a temporary filter cake at the formation face to reduce or eliminate the fluid leakoff out of the wellbore.

  • Publication number: 20180347332
    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.
