  • Patent number: 10590334
    Abstract: A well treatment fluid contains a surface modifying treatment agent having an anchor and a hydrophobic tail. The surface modifying treatment agent is an organophosphorus acid derivative. After the well treatment fluid is pumped into a well penetrating the subterranean formation, the anchor binds to the surface of the formation. The subterranean formation is a siliceous formation or a metal oxide-containing subterranean formation. The anchor bonds to a Si atom when the formation is a siliceous formation and to the metal of the metal oxide when the formation is a metal oxide-containing formation. After being bound to the surface of the formation, frictional drag within the well is reduced. This allows for faster recovery of formation fluids. The bonding of the surface modifying treatment agent onto the formation may further be enhanced by first pre-treating the formation with an aqueous fluid.

  • Patent number: 10544353
    Abstract: A surfactant that changes the wettability of tight sandstone and its preparation method and application. By adding the aqueous phase solution into the oil phase solution, and under the action of the emulsifier, a uniformly dispersed phase is achieved. Then adding initiator, stirring and raising the temperature, reacting the reaction at the temperature to obtain a colorless and transparent liquid, i.e., high polymer. At room temperature, adding fluorocarbon surfactant and biosurfactant and stirring was continued for 4 hours to obtain a surfactant that changes the surface wettability of tight sandstone. The surfactant of the present invention can reduce the oil-water interfacial tension, transform the oil-wet surface into water-wet surface, which reduces the adhesion of oil droplets to rock surface and improves the flowability of crude oil in the original stratum, and improves the recovery of low-permeability reservoir.

    Abstract: Uncertainty of microseismic monitoring results can be reduced to improve hydraulic fracture modeling. A computing device can use a fracture model to determine a predicted geometry of a hydraulic fracture in a subterranean formation based on properties of a fracturing fluid that is introduced into the subterranean formation. An uncertainty index of the predicted geometry of the hydraulic fracture can be determined based on an uncertainty value of the predicted geometry and a trend of uncertainty values. When the injection flow rate of the fracturing fluid is less than a maximum flow rate, it can be increased from an initial injection flow rate to an increased injection flow rate in response to determining the uncertainty index exceeds a pre-set maximum.

  • Patent number: 9366124
    Abstract: A packer on a tubing string and diverting material pumped down the tubing string may be used to isolate a fracture cluster in a multizone horizontal wellbore that has been previously hydraulically fractured. Once hydraulically isolated, fluid may be pumped down the tubing string to re-fracture the previously fractured fracture cluster in an effort to increase hydrocarbon production from the horizontal wellbore. The tubing string may include a testing device used to determine whether a specific fracture cluster within the horizontal wellbore should be re-fractured. Diverting material may be pumped down the tubing string and positioned adjacent a fracture cluster to hydraulically isolate the fracture cluster during the re-fracturing process. The diverting material may be cleaned out of the horizontal wellbore after all desired fracture clusters along the horizontal wellbore have been individually re-fractured.

  • Patent number: 9157022
    Abstract: Water soluble uncrosslinked polysaccharides may be fluid loss control agents for viscoelastic surfactant (VES) fluids used for stimulation (e.g. fracturing) or well completion in hydrocarbon recovery operations. The VES fluid may further include proppant or gravel, if it is intended for use as a fracturing fluid or a gravel packing fluid, although such uses do not require that the fluid contain proppant or gravel. The water soluble uncrosslinked polysaccharide fluid loss control agents may include, but not be limited to guar gum and derivatives thereof; cellulose and derivatives thereof; propylene glycol alginate; salts (e.g. sodium, potassium, and calcium salts) of iota, kappa, and lambda carrageenan; agar-agar; xanthan gum; and the like; and/or mixtures thereof. The fluid loss control agent may be added to the aqueous viscoelastic treating fluid prior to VES addition, and/or at the same time and/or after the VES is added.
