  • Patent number: 10266757
    Abstract: A method for improving the performance of fracturing processes in oil production fields may rely on polymer coated particles carried in the fracturing fluid. The particles may include heavy substrates, such as sand, ceramic sand, or the like coated with polymers selected to absorb water, increasing the area and volume to travel more readily with the flow of fluid without settling out, or allowing the substrate to settle out. Ultimately, the substrate may become lodged in the fissures formed by the pressure or hydraulic fracturing, resulting in propping open of the fissures for improved productivity.

  • Patent number: 10221649
    Abstract: The disclosure pertains to the design and implementation of a diversion procedure for geologic openings. Embodiments involve performing a screening analysis to determine if a well or formation is appropriate for stimulation. If a well is appropriate, a modeling analysis is performed to determine candidate parameters for a diversion procedure. The analysis is divided into two segments, a dry analysis of jamming and a wet and full-physics-based analysis of plugging. The jamming analysis provides candidates to the plugging analysis to reduce the work of the more intensive wet full-physics modeling.

  • Patent number: 10196888
    Abstract: Improving the flow of hydrocarbons from shale lateral wellbores in unconventional wellbores may be accomplished with various configurations of assisting lateral wellbores and/or kick-off wellbores from primary lateral wellbores and/or secondary or assisting lateral wellbores. By extending fracture networks from adjacent lateral wellbores and/or adjacent kick-off wellbores so that the fracture networks from different wellbores are in fluid communication with one another, the flow of various fluids between the adjacent wellbores provides another dimension of control over the wellbores and fracture networks used to recover hydrocarbons from the shale intervals of interest.

  • Patent number: 10174568
    Abstract: A treatment fluid that comprises a carrier fluid and a degradable material in the form of particles, fibers or both is provided or prepared. The treatment fluid is placed in a borehole such that the treatment fluid contacts a liner, a downhole filter, perforations, natural fractures, induced fractures, or a subterranean formation or combinations thereof. The treatment fluid is allowed to flow into the liner, downhole filter, perforation, natural or induced fracture or subterranean formation such that the degradable material forms at least one plug or filter cake (or both), preventing or reducing further fluid movement between the wellbore and the subterranean formation. The degradable material is then allowed to dissolve after a period of time, causing the plug or filter cake (or both) to weaken, thereby allowing removal of the plug or filter cake (or both) and reestablishing fluid movement between formation and the wellbore.
