Treatment Of Produced Fluids Patents (Class 166/75.12)
  • Patent number: 9328856
    Abstract: A system and method for improving oil-and-water separation in a blended fluid stream are presented. The system includes a pressure reduction device that causes cyclonic flow in the stream. The pressure reduction device may be a wafer-based hydrocyclone or a modified hydrocyclone having an underflow outlet but no overflow outlet. The system may also include a valve that is located upstream or downstream of the pressure reduction device. Both the valve and the pressure reduction device reduce the pressure of the fluid stream while reducing the shearing of oil and water droplets within the stream. As a result, the droplets are more likely to coalesce and less likely to form emulsions, thus improving oil-and-water separation in downstream treatment processes.

  • Patent number: 8623221
    Abstract: A sand separator for capturing sand and rock debris from recovered natural gas fracturing fluid includes a cylindrical, high-pressure-rated vessel disposed vertically and immediately downstream of the gas wellhead. High pressure fracturing fluid enters the top of the separator into an inner flue extending coaxially downward to terminate a spaced distance above the bottom of the vessel. Transverse baffles spaced apart along the length of the flue extend through the flue to the inner walls of the vessel to keep the flue centered within the separator. As the fluid enters the separator, openings through the flue near the vessel inlet permit lighter weight and gaseous constituents to escape the fluid and bypass the flue, thereby reducing the velocity of the fluid remaining inside the flue. As the remaining fluid falls to the bottom of the vessel, it further slows as it reverses direction to rise between the flue and the vessel walls.

  • Patent number: 8439999
    Abstract: A device for capturing gas included within a produced-water stream is described. Gas and water pressure coordination is not required. Controls prevent liquid entry to the gas system and prevent gas entry into the water system. A gas/liquid separator receives an inner vessel lower end. A separator inlet receives a combined fluid stream. A liquid line passes into the inner vessel and down into the separator below the inlet so that liquid separated from the combined stream will flow up the liquid line. Motor valves are in the liquid line and in a gas line. The gas line extends from the inner vessel upper end. The gas line conveys gas from the inner vessel upper end to a gas collection system. A top float in the inner vessel activates the gas line motor valve. A bottom float in the inner vessel activates the liquid line motor valve.

  • Patent number: 8371380
    Abstract: Methods and systems relate to generating a flow of steam and splitting the flow of steam to enable both its injection into a formation to assist in oil recovery and its introduction into a pathway where the steam is used for generating electricity and capturing carbon dioxide (CO2). At least part of the CO2 that is captured comes from burning of fuel used to generate the steam. Steam assisted gravity drainage requires the steam that is injected to have a higher pressure than the steam that is needed for CO2 capture. Exhaust steam from a steam turbine used to generate the electricity reduces pressure of the steam prior to use of the steam for capturing CO2.

  • Publication number: 20120325470
    Abstract: An integrated thermal recovery process using a solvent of a pentane or hexane or both as an additive to, or sole component of, a gravity-dominated process for recovering bitumen or heavy oil from a reservoir. A pentane-hexane specific solvent fraction is extracted at surface from a diluent stream. That pentane-hexane solvent fraction is then injected into the reservoir as part of a gravity-dominated recovery process within the reservoir, and when that solvent fraction is subsequently produced as part of the oil or bitumen blend, it is allowed to remain within the blend to enhance the subsequent blend treating and transportation steps. Meanwhile, the remainder of the diluent from which the solvent stream had been extracted is utilized at surface as a blending stream to serve as an aid in treating of produced fluids and also to serve as a means of rendering the bitumen or heavy oil stream pipelineable.

    Abstract: Apparatus and methods for recovering hydrocarbonaceous and additional products from nonrubilized oil shale and oil/tar sands. One or more initial condensation steps are performed to recover crude-oil products from the effluent gas, followed by one or more subsequent condensation steps to recover additional, non-crude-oil products. At least a portion of the exhaust gas from a combustor may be routed through a heat exchanger to produce the processing gas, the composition of which may be adjusted so that it contains approximately 1% oxygen or less. The subsequent condensation steps may be carried out in at least one cooled chamber having a sequence of critical orifices maintained at a negative pressure. Carbon sequestration steps may be performed wherein recovered carbon dioxide is delivered down the hole following the recovery of the hydrocarbonaceous products. Various physical parameters may be adjusted to vary the recovery of crude oil or other products or contaminants from the effluent gas.
