  • High impulse energy and liquid membrane scale removal
    Patent number: 4671360
    Abstract: A process wherein energy generated from a high impulse device is used to jar, loosen, or dislodge scale from a wellbore, downhole production equipment, or near well formation flow channels. Such jarred, loosened, or dislodged scale allows for increased amounts of scale-forming ions to be removed. Alterwards, an emulsified liquid membrane system containing surfactants therein sufficient to remove scale-forming ions is placed in said wellbore. Said emulsified membrane system is removed when the scale-forming ions have been absorbed therein.

  • Method to improve vertical hydraulic fracturing in inclined wellbores
    Patent number: 4669546
    Abstract: A method for improving vertical hydraulic fracturing of an inclined wellbore through in-line openings in said wellbore. Via this method, the initiation, growth, and propagation of vertical fractures are controlled.

  • Minimizing formation damage during gravel pack operations
    Patent number: 4664191
    Abstract: A method for minimizing formation damage during gravel packing operations in a loosely consolidated hydrocarbonaceous fluid producing formation penetrated by at least one well. Solidifiable chemical blocking agents are used to keep intrusive fluids, e.g. kill fluids, from the hydrocarbonaceous fluid producing interval of said formation during said gravel packing operation.

  • Foam enhancement of controlled pulse fracturing
    Patent number: 4617997
    Abstract: The effectiveness of controlled pulse fracturing treatment ("CPF") is enhanced by creating a foam when energy is released from the pulse device. Foam created by a foaming agent in the wellbore fluid increases said fluid's apparent viscosity and controls fluid loss. The increased viscosity causes additional fracture propagation. Upon commencement of production of hydrocarbonaceous fluids, fines and debris resultant from CPF are transported from the fractures which cleans up the well.

  • Apparatus for plugging a wellbore in high impulse fracturing
    Patent number: 4605061
    Abstract: An apparatus for plugging a wellbore with a solid gel plug stem in high impulse or high energy fracturing. This apparatus facilitates the removal of the propellant canister support means, the propellant ignition means, as well as any debris adhering thereto. By this apparatus, damage to the wellbore and formation is minimized.
