  • Patent number: 10508527
    Abstract: Methods for creating vertical mini-holes in a subterranean formation while creating multi-directional Bernoulli-induced fractures therein are provided. These methods are particularly useful in horizontal or deviated wells. In some embodiments, the method includes forming a mini-hole in the subterranean formation perpendicular to the deviated wellbore. The mini-hole is in fluid communication with the deviated wellbore at a proximal end and has a tip located at a distal end. The method further includes injecting fluid into the mini-hole with a maximum pressure forming at the tip so as to initiate a fracture along local formation stresses proximate the tip of the mini-hole.

  • Patent number: 10436004
    Abstract: Methods including isolating a first treatment zone comprising an opening into a subterranean formation. A high-viscosity treatment fluid (HVTF) is introduced through the opening and incrementally increased fracturing rate steps (IIFRSs) are applied to create or enhance a dominate fracture, wherein between each IIFRS a downhole pressure slope over time will increase, decline, or stabilize at a measured pressure slope. The measured pressure slope is evaluated to determine whether an increasing pressure slope, a stabilizing pressure slope, or a declining pressure slope exists to determine whether and when to apply a subsequent IIFRS. The result is increasing a volume of the dominate fracture due to efficient dominate fracturing with generated back pressure until a first maximum fracturing rate is reached.

  • Patent number: 9879175
    Abstract: A capsule for carrying a proppant for emplaced in a formation containing formation fluid by a hydraulic fracture operation using a fracturing fluid. The capsule includes a capsule body. The capsule body includes a proppant. There is a surface layer on the capsule body that is permeable to the formation fluid or the fracturing fluid or is permeable to both the formation fluid and the fracturing fluid. The proppant material is dry cement that interacts with the formation fluid or the fracturing fluid or both the formation fluid and the fracturing fluid that migrate through the surface layer and is taken up by the dry cement causing the dry cement to harden.

  • Patent number: 9845670
    Abstract: Systems and methods for placing proppant in a portion of a subterranean formation (e.g., in a fracturing operation) using two or more immiscible fluids are provided. In certain embodiments, the methods comprise: introducing into a well bore penetrating a portion of a subterranean formation alternating stages of a first treatment fluid comprising one or more proppants, and a second treatment fluid comprising a lesser concentration of proppants than the first fluid, wherein the first fluid and the second fluid are substantially immiscible in one another, and wherein the alternating stages of the first and second treatment fluids are introduced into the well bore at or above a pressure sufficient to create or enhance one or more fractures in the subterranean formation.

  • Patent number: 9828843
    Abstract: The disclosure provides a method of treating a subterranean formation penetrated by a wellbore. The method includes introducing a gas phase gas into fractures of the subterranean formation extending from the wellbore, followed by introducing a carrier fluid into the subterranean formation under sufficient pressure to fracture a portion of the subterranean formation and release hydrocarbons from the subterranean formation. The gas phase gas occupies the fractures at a sufficient pressure to cause the carrier fluid to be diverted to additional fractures of the subterranean formation defined by the portion.

  • Patent number: 9816365
    Abstract: A method of servicing a wellbore in a subterranean formation comprising placing in the wellbore and/or subterranean formation a pad fluid and forming a fracture in the subterranean formation. Next, a first slurry fluid may be placed into the fracture in the subterranean formation. The first slurry fluid may comprise a reducible material and a first particulate material. Next, a second slurry fluid and a spacer fluid may be placed into the fracture in the subterranean formation in an alternating sequence. The second slurry fluid may comprise a second particulate material. Then, the fracture is allowed to close and the fluids are allowed to break. Finally, the reducible materials degrade, to form a particulate-laden proppant pack (PLPP).

    Abstract: The fracturing methods can provide an advantage over the current fracturing methods. The disclosed fracturing methods can change the fracture gradient of the downhole subterranean formation. For example, one or more of the fracture gradients of the low and high stress zones of the downhole subterranean formation can be changed. Furthermore, the methods of present disclosure, in relation to current practices, can decrease the extent and/or degree of fracturing within low stress downhole formations and increase the degree of fracturing within high stress formations.

  • Patent number: 9637675
    Abstract: Loss of wellbore fluids (such as drilling fluids, completion fluids and workover fluids) into the flow passages of a subterranean formation may be reduced or eliminated by introducing into the wellbore in communication with the formation a composition containing a composite of a deformable core having a hardened coating which contains a viscosifying agent and, optionally, a crosslinking agent. The viscosity of the composition increases in-situ as the viscosifying agent, and optional crosslinking agent, disassociate from the deformable core and react. A fluid-impermeable barrier is thereby formed. The composites may also be used in spacers, well cements, workover and completion fluids as their need arises.
