  • Patent number: 10202289
    Abstract: Method and apparatus are provided for treating salt water. In the method, a feed water is run through a skimmer unit to form de-oiled water. The de-oiled water is passed through an electrocoagulation unit to form electrocoagulated water. A precipitating agent is added to the electrocoagulated water and stirred to form a water/floc mixture. A polymeric coagulation enhancing agent is added to the water/floc mixture with mild stirring and coagulants in the mixture are permitted to settle. A partly clarified water from the mixture is drawn out from a level above the settled coagulants. The partly clarified water is run through at least one settler and coagulants are removed from the bottom of the at least one settler. A clarified salt water stream is withdrawn from the final settler. The necessary equipment can be mounted on a trailer.

    Abstract: A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

  • Patent number: 8789622
    Abstract: A continuous microwave particulate treatment system for treating fluid from a wellbore. The system uses a material 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 and treatment system controllers.

    Abstract: A system for conditioning drilling fluid includes a conditioning device having a first conduit configured to receive the drilling fluid, a flow restriction disposed adjacent the first conduit, the flow restriction comprising a fluid inlet and a fluid outlet, an impact plate disposed downstream of the flow restriction, a first chamber disposed between the flow restriction and the impact plate, and a second chamber disposed downstream of the impact plate, wherein the first chamber is fluidly connected to the second chamber. A method for conditioning drilling fluid using a conditioning device, includes pumping a drilling fluid through a flow restriction, accelerating the drilling fluid into a mixing chamber, subjecting the drilling fluid to elongational shearing, decelerating the drilling fluid against an impact plate, subjecting the drilling fluid to impact shearing, and emptying drilling fluid from the mixing chamber.

  • Patent number: 8753517
    Abstract: A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.

  • Publication number: 20140060838
    Abstract: The invention relates to the completion and enhancement of oil and gas wells. The invention provides for a downhole tool which: enters vertical or horizontal wells located adjacent to the oil and gas bearing formation, parts the casing and extends outward forming micro-boreholes necessary to remove residual oil and gas which remain in place. After the initial fluid production has been harvested, the invention can be employed on new or old wells and can operate in all conditions which wells encounter during the standard drilling process. The process of micro-holes can replace the process known as “fracking”. Fracking is being employed; however the process is being reviewed due to safety of human life. The invention employs special alloys and procedures to form the extended reach micro-boreholes.

  • Patent number: 8651201
    Abstract: A combined cuttings stream inlet and air stream outlet apparatus, for placement within the inspection hatch of a conventional drill cuttings box, is disclosed. The combined cuttings stream inlet and air stream outlet apparatus has a central cuttings stream inlet conduit, disposed within a larger air stream outlet conduit. The air stream outlet conduit is sized to closely engage the diameter of the inspection hatch when inserted into the hatch opening. The annulus between the two conduits forms a flow area for air to exit the cuttings box. In use, the combined apparatus is easily inserted into the hatch opening of the cuttings box, preferably with a gasket between the apparatus and the hatch opening, and is held in place by the cuttings/air stream. When the cuttings box is full, the apparatus is simply pulled out and inserted into an empty cuttings box.
