In one embodiment, the heavy metal precipitates remain in the formation. After the recovery of the produced fluid, the dilution fluid containing the heavy metal complexes is separated from the produced fluid, generating a treated produced fluid having a reduced concentration of heavy metals. In one embodiment, the dilution fluid is water, and the wastewater containing the heavy metal complexes after recovery can be recycled by injection into a reservoir.

  • Patent number: 9016374
    Abstract: Working fluids, such as drilling fluids, may remove heat from other fluids, tools, equipments and environments and transfer it to other locations by using reversible phase change elements. The heat removal occurs through the absorption of heat by one or more phase transitions or a sequence of phase transitions in the elements of the working fluid. For instance, heat is absorbed when the phase change portions of the reversible phase change elements change phase including, but not necessarily limited to, a change from solid to smectic liquid crystal, from solid to nematic liquid crystal, from smectic liquid crystal to isotropic liquid, from nematic liquid crystal to isotropic liquid, from solid to isotropic liquid, and sequences and combinations thereof. Heat is released when the phase change reverses. These phase changes are first-order transitions and are associated with a latent heat or enthalpy.

  • Patent number: 9010428
    Abstract: The swelling rate of a swelling packer element or a conforming foam screen material is accelerated with heat. Ferromagnetic particles or electrically conductive resins or polymers are interspersed in the swelling material and heat is generated at the particles by an inductive heater. A dielectric mandrel or base pipe can be used to focus the heating effect on the ferromagnetic particles or the electrically conductive resins or polymers in the sealing element or swelling foam screen element to focus the heating there without heating the base pipe. The heat accelerates the swelling process.

  • Publication number: 20150101814
    Abstract: Hydrocarbon-containing rocks comprising type IIs kerogen are introduced into an excavated enclosure (e.g. a pit or an impoundment) to form a bed of rocks therein. One or more heaters (e.g. molten salt heaters) are operated to pyrolyze type IIs kerogen of the rocks. In some embodiments, a hydrocarbon reflux loop is maintained within the enclosure to convectively heat the type IIs-kerogen-containing rocks by boiling hydrocarbon liquids from a reservoir at the bottom of the enclosure so that vapor passes to the top of the enclosure, condenses, and falls back through the bed. Alternatively or additionally, the rocks may be heated by heaters embedded within wall(s) and/or a floor of the enclosure.

  • Patent number: 8997869
    Abstract: Disclosed herein are methods for extracting a kerogen-based product from subsurface (oil) shale formations. These methods rely on chemically modifying the shale-bound kerogen using a chemical oxidant so as to render it mobile. The oxidant is provided to a formation fluid in contact with the kerogen in the subsurface shale. A mobile kerogen-based product which includes the organic acids is withdrawn from the subsurface shale formation and processed to isolate the organic acids contained therein. The isolated organic acids are upgraded by a reaction process that make the products suitable as refinery feedstocks, fuel or lubricant blendstocks, reaction intermediates, chemical feedstocks, or chemical intermediate blendstocks.

  • Patent number: 8991510
    Abstract: A system comprises an injection well for accessing a reservoir containing a native fluid comprising a hydrocarbon. The reservoir is located below one or more caprocks, is at a first temperature, and is accessible without using large-scale hydrofracturing. The system further includes a production well in fluid communication with the reservoir, a supply apparatus configured to feed a non-water based working fluid at a second temperature that is lower than the first temperature through the injection well to the reservoir. The working fluid mixes with the native fluid to form a production fluid comprising at least a portion of the working fluid and at least a portion of the hydrocarbon at a third temperature that is higher than the second temperature. An energy recovery apparatus in fluid communication with the productions well converts energy contained in the production fluid to electricity, heat, or combinations thereof.

  • Patent number: 8978755
    Abstract: The method begins by forming a gravity drainage production well pair within a formation comprising an injection well and a production well. The pre-soaking stage begins by soaking at least one of the wellbores of the well pair with a solvent, wherein the solvent does not include water. The pre-heating stage begins by heating the soaked wellbore of the well pair to produce a vapor. The squeezing stage begins by introducing the vapor into the soaked wellbore of the well pair, and can thus overlap with the pre-heating stage. The gravity drainage production begins after the squeezing stage, once the wells are in thermal communication and the heavy oil can drain to the lower well.
