  • Patent number: 9896917
    Abstract: The oil production intensification method includes injecting the reagent into the reservoir and treating the bottom zone of the well with high voltage pulse discharges with an electric discharge device continuously traveling from bottom to top in the atmosphere of such reagent. The number of pulses of such high voltage pulse discharges is set subject to the real porosity of the reservoir and the empirical dependence of the number of pulses of high voltage pulse discharges per meter of the reservoir and porosity of rocks pre-estimated with the core material. After the electric discharge device stops traveling up, the treatment with high voltage pulse discharges also stops, and the well is pressurized until the pressure stabilizes in it. Then, the bottom hole area of the well is further treated with high voltage pulses as the electric discharge device travels from top to bottom. Whereby an intensified oil production is realized, from 2 to 20 times more oil may be extracted.

  • Patent number: 9896923
    Abstract: A technique facilitates a fracturing operation by maintaining the heterogeneity of proppant fluid as it is injected into reservoir fractures. The technique comprises using a blender to deliver proppant material in a pulsating manner to create pulses of proppant. The pulses of proppant are mixed with a fluid to create a proppant slurry having the pulses of proppant material separated by a second fluid. The proppant slurry is then split between a plurality of pumps which are operated to pump the slurry to a well. To maintain heterogeneity, the pump rates of the pumps are individually adjusted to control dispersion of the pulses of proppant downstream of the pumps and to substantially maintain the separated pulses of proppant material in the slurry. A wide variety of other system adjustments also may be made for enhancing the ability of the overall fracturing system to maintain separated pulses of concentrated proppant material.

  • Patent number: 9809716
    Abstract: Inadvertent or unavoidable contact of an acid with an acid-reactive substance may preclude the acid's use in another location where its reactivity is more desired. Excessive reactivity of acids toward acid-reactive substances may lead to undesired effects such as surface erosion, matrix deconsolidation, scaling, and the like. Methods for protecting an acid-reactive surface from excessive reaction may comprise: depositing a protective coating comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof onto an acid-reactive surface; and contacting a mineral acid or an organic acid with the protective coating without substantially reacting the acid-reactive surface.

  • Patent number: 9803442
    Abstract: A method to induce pressure transients in fluids for use in hydrocarbon recovery operations by inducing the pressure transients in a fluid by a collision process. The collision process employs a moving object (103,203,303,403) that collides outside the fluid with a body (102,202,302,402) that is in contact with the fluid inside a partly enclosed space (101,201,301,401). Furthermore, the pressure transients must be allowed to propagate in the fluid. The fluid may be one or more of the following group: primarily water, consolidation fluid, treatment fluid, cleaning fluid, drilling fluid, fracturing fluid and cement.
