  • Patent number: 11274244
    Abstract: This invention describes and claims the stimulation of several Wolfcamp and Bone Springs targeted wells in the northern Delaware Basin using fracturing treatments and a new method employing relatively small pre-pad pill volumes of Brine Resistant Silicon Dioxide Nanoparticle Dispersions ahead of each stage of treatment have been successfully performed. The invention includes a method of extending an oil and gas system ESRV comprising the steps of adding a Brine Resistant Silicon Dioxide Nanoparticle Dispersion (“BRINE RESISTANT SDND”) to conventional oil well treatment fluids. The invention also includes a method of increasing initial production rates of an oil well by over 20.0% as compared to wells either not treated with the BRINE RESISTANT SDND technology or treated by conventional nano-emulsion surfactants. The Method focuses on the steps of adding a Brine Resistant Silicon Dioxide Nanoparticle Dispersion to conventional oil well treatment fluids.

  • Publication number: 20120255887
    Abstract: Method for recovery of bitumen from tar sand is provided. An aqueous fluid containing a wetting agent and nanoparticles is injected into a first horizontal well at a temperature above reservoir temperature. Bitumen is released from sand grains and flows into a second horizontal well, where it is transported to surface. In a surface treatment facility, a slurry of tar sand is formed and surfactant and nanoparticles are added to the slurry.

  • Publication number: 20120175120
    Abstract: Nanoparticles are added to a fluid containing a wetting agent and the fluid is pumped down a well to enhance wetting of solid surfaces in and around the well before pumping an acid solution down the well. After acid is pumped, a fluid containing nanoparticles and wetting agent is again pumped down the well, leading to improved flow capacity of the well.

  • Publication number: 20120168165
    Abstract: Nanoparticles are added to a fluid containing a wetting agent to enhance wetting of solid surfaces in and around the well and removing a water-block from the well. The wetting agent and nanoparticles combine to produce a wetting of the surfaces of the rock that allows recovery of the excess water near the well (water block).

  • Patent number: 5929437
    Abstract: Radioactive particles are provided for use in tracing the flow path in or near a well of fluids injected into the well. The particles include an element which can be made radioactive by bombardment with neutrons and a material to encapsulate the element. The encapsulant is preferably an organic polymer having a high softening temperature.
