  • Patent number: 10857488
    Abstract: A system for separating solids from a fluid includes a containment vessel having a V-shaped tank in fluid communication with an agitated overflow tank. Baffles within the V-shaped tank provide a series of zones where the fluid is deposited for processing. A shaftless auger at the bottom of the V-shaped tank transfers solids to an area where they are pumped to a first hydrocyclone assembly associated with a first shaker. Overflow from the hydrocyclone assembly and underflow from the first shaker is further processed by a second hydrocyclone assembly associated with a second shaker. Overflow from the second hydrocyclone assembly and underflow from the second shaker are deposited into overflow tank which contains the cleaned fluid.

  • Publication number: 20140332282
    Abstract: This application relates to an apparatus and method for cleaning drill cuttings recovered from a wellbore. Specifically, the apparatus includes an effective system for handling and washing drill cuttings at a well site to remove hydrocarbon contaminants. The system successively washes hydrocarbon contaminated drill cuttings in organic solvent and water to remove and recover the hydrocarbon contaminates, and produce cleaned drill cuttings that may enable disposal of clean drill cuttings without further treatment.

  • Patent number: 8871097
    Abstract: A method of reclaiming a formate brine may include increasing the pH of a spent formate brine fluid comprising water-soluble polymers; treating the fluid with an oxidizing agent; and removing at least a portion of suspended solids from the fluid. Further, a method of reclaiming a formate brine may include lowering the pH of the spent formate brine fluid comprising water-soluble polymers; increasing the pH of the spent formate brine fluid to initiate precipitation of materials solubilized in the fluid; treating the fluid with an oxidizing agent to break down remaining water-soluble polymer; and recovering at least a portion of the formate brine.

  • Patent number: 8844650
    Abstract: The present invention is generally directed to a closed loop apparatus, system, process or method adapted for processing drilling mud used in a down hole well drilling process such that any undesirable particulate such as cuttings will be substantially, if not completely separated from the dirty mud while at the same time allowing the recycled drilling mud to be continuously circulated with the drilling mud. In one embodiment, the present invention includes the following components, all in fluid or mud flow communication with one another and with an adjacent drilling rig: at least one clean mud mixing tank, at least one pump system, at least one dirty mud shakers, at least one optional conveyor belt system, at least one recycled mud reclamation tank and one or more filtering centrifugal pumps or centrifuge systems.

  • Publication number: 20140262510
    Abstract: A closed loop drilling fluids circulation system includes a first drilling fluid circulation system disposed at a first subterranean drill site. The first drilling fluid circulation system includes a supply tank for holding clean drilling fluid and a solids control device configured to separate solids from used drilling fluid. In addition, the system includes a central processing facility disposed at a location remote from the first drill site and configured to receive used drilling fluid from the solids control device and supply clean drilling fluid to the supply tank.

  • Patent number: 8834726
    Abstract: A method of treating a wastewater is provided and can be used, for example, to treat a gas well hydrofracture wastewater. The method can involve precipitating barium as barium sulfate, precipitating calcium and strontium as calcium carbonate and strontium carbonate, precipitating magnesium hydroxide, and filtering out the metal compounds to form a recycle water. The recycle water produced from the method is also provided, as is a method for using the recycle water as a gas well hydrofracture water. In some embodiments, discharge water from a coal mine, and/or water from an abandoned coal mine, is used as a source of sulfate ions to precipitate barium as barium sulfate.

  • Patent number: 8813875
    Abstract: A drilling rig with continuous microwavable particulate treatment system for treating fluid from a wellbore on an offshore platform. The system uses a materials handling controller, a vibrating sieve device or filtering device to separate particulate from drilling fluid, a cuttings discharge collection device for continuously moving the slurry to a cuttings processing station, a treatment system controller controlling the continuous cuttings processing station that uses a microwave generator creating microwaves that heat the slurry and a plurality of non-deforming microwave heatable polishing and grinding media in a vibrating trough. The system continuously creates water vapor with oil droplets and cleaned cuttings, and a vapor recovery system is used for removing the oil droplets from the water vapor having a vapor recovery system controller in communication with the material handling controller and treatment system controller.
