  • Patent number: 10711176
    Abstract: The present invention is a device and a method that combines a carbon disulfide-releasing chemical with a low pH organic or inorganic acid to produce a carbon disulfide-containing fluid at or near the point of injection that minimizes or eliminates the possible exposure of carbon disulfide to workers and the environment. In one particular embodiment a positive displacement injection pump injects the carbon disulfide-containing fluid into a crude oil system for treating crude oil transmission lines and in downhole tubulars to remove paraffin deposits. The device uses a unique in-line motion mixer to mix two fluids. The device is electronically controlled locally and remotely with the system operating data displayed locally and transmitted remotely. The paraffin treating carbon disulfide-containing fluid and supplemental chemicals dissolve, disperse and remove paraffin deposits.

  • Patent number: 9580996
    Abstract: A method for processing a flowback composition stream from a well head includes controlling a first flow rate of the flow back composition stream to a second flow rate by regulating the flowback composition stream from a first pressure to a second pressure. The method also includes separating the flowback composition stream into a first gas stream and a condensed stream. The method includes discharging the condensed stream to a degasser and degassing a carbon dioxide rich gas from the condensed stream. The method also includes mixing the carbon dioxide rich gas stream with the first gas stream to produce a second gas stream. The method includes controlling a third flow rate of the second gas stream by regulating a third pressure of the second gas stream to a fourth pressure that is different than the third pressure.

  • Patent number: 9546314
    Abstract: Methods and compositions are described for treating water- and hydrocarbon-producing subterranean formations with a relative permeability modifier at concentrations below those conventionally used in the art, while not substantially impacting the treatment fluid's performance. Treatment fluids described herein comprise a base fluid, a relative permeability modifier comprising a hydrophobically modified hydrophilic polymer, and a companion polymer interacting synergistically with the relative permeability modifier such that the treatment fluid is operable to reduce the water permeability or to increase an aqueous fluid injection pressure of at least a portion of a subterranean formation by more than the relative permeability modifier or the companion polymer acting alone at like concentration. The water permeability reduction and/or the aqueous fluid injection pressure increase can be more than additive.

  • Patent number: 9168482
    Abstract: A method for capturing dust generated during movement of sand through a sand delivery system includes positioning an inlet at a first end of each of a plurality of conduits for collecting dust in a corresponding space surrounding a corresponding point along a conveyor. A second end of each of the plurality of conduits is coupled in fluid communication with a manifold system including at least one manifold extending generally parallel to the ground. Substantially an entire length of the conveyor, including the space corresponding to the inlet of each of the plurality of conduits, is covered with a cover for containing dust generated during movement of sand along the conveyor. Air is drawn through the manifold system and the plurality of conduits to capture dust generated during the movement of sand along the conveyor through the inlet of each of the plurality of conduits.

  • Patent number: 9034180
    Abstract: Disclosed is an improved water treatment cavitation reactor cone. The tank operates on a continuous flow of fluids which are subjected to ultrasonic waves in combination with a high level of injected ozone. The treatment tank includes a tangential inlet that induces a rotating flow into the tank thereby increasing the mixing of the ozone within the effluent. The effluent is further treated with DC current. The treatment tank provides a cost efficient and environmentally friendly process and apparatus for cleaning and recycling fluids as contaminated as frac water, used to stimulate gas production from shale formations, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids. The calcium carbonate scaling tendency is reduced to an acceptable level without the use of acids, ion exchange materials, or anti scaling chemicals which is of economical and environmental significance and benefit.

  • Patent number: 8997863
    Abstract: A method of improving natural gas release from a well via an enhanced hydraulic fracturing operation. The method includes capturing or retrieving the flow back from the well following the fracturing operation. The flow back or other source water is introduced to an electrocoagulation (“EC”) treatment process. EC treatment separates the water from other fracturing fluid components in the flow back and also removes bacteria and other contaminants. Thereafter, the EC-treated fluid is recycled for subsequent fracturing operations. The process may also be used to treat all source water, including fresh water delivered to the well before it is used as a fracturing fluid.
