  • Patent number: 11242733
    Abstract: A well production method uses side gas lift valves above a packer and an ESP below the packer. In a gas lift mode, a controller turns the ESP motor off, and shifts a tubing valve below the packer to a gas lift position while flowing gas down the casing. While in the gas lift mode, a pressure gauge monitors motor lubricant pressure, which correlates with a flowing bottom hole pressure of the well fluid in the lower casing annulus. In an ESP mode, the controller stops the flow of gas from the gas source, shifts the tubing valve to an ESP position and turns on the motor, causing well fluid to flow through the pump intake. The pressure gauge continues to monitor the lubricant pressure during the ESP mode.

The method includes degasifying the wastewater for the removal of dissolved gases and thereafter chemically softening the wastewater. After the chemical softening step, the wastewater is directed through a media filter or membrane which removes additional solids and precipitants. Thereafter the wastewater is directed through a sodium ion exchange that further softens the wastewater. The effluent from the ion exchange is directed through a cartridge filter and the effluent from the cartridge filter is directed through one or more reverse osmosis units. At a selected phase of the process, prior to the wastewater reaching the reverse osmosis unit or units, the pH of the wastewater is raised and maintained such that the pH of the wastewater reaching a reverse osmosis unit is at a pH greater than 10.5.

  • Patent number: 10590749
    Abstract: Methods for making efficient use of steam in a steam-assisted gravity drainage (SAGD) process for recovering heavy oils from tar sands and similar petroleum deposits are disclosed. The methods utilize a surfactant to generate steam foam in ways that maximize efficient use of steam. In some aspects, steam foam is used in water layers or gas caps that reside above steam chambers to prevent loss of steam from the steam chamber. The predominant use of relatively dry steam in SAGD processes makes it challenging to find ways to introduce surfactants and generate steam foam. However, decreasing the mobility of the steam by converting at least some of it to foam allows the wellbore and steam chambers above the injection site to be more fully developed, provides for more effective heat transfer to the heavy oil and rock, improves production, and allows recovery of the heavy oil with a minimum amount of steam usage.

  • Patent number: 9080443
    Abstract: A down hole fluid conditioning assembly, includable within a drilling bottom hole assembly or other tool configuration, creates a vortex to separate fluids such as drilling mud and the like into a lower density first portion and higher density second portion. The lower density first portion is directed toward the bottom hole assembly or other equipment to improve operational performance of the bottom hole assembly or other equipment.

  • Patent number: 9010440
    Abstract: Embodiments of the present invention generally relate to methods and apparatus for centrifugal separation. In one embodiment, a separator includes an outer tubular having ends sealed from the environment and an inner tubular. The inner tubular is disposed within the outer tubular, has ends in fluid communication with a bore of the outer tubular, and is attached to the outer tubular. The separator further includes an inlet. The inlet is disposed through a wall of the outer tubular, in fluid communication with a bore of the inner tubular, and tangentially attached to the inner tubular so that fluid flow from the inlet to the inner tubular is centrifugally accelerated. The separator further includes a gas outlet in fluid communication with the outer tubular bore; and a liquid outlet in fluid communication with the outer tubular bore.

  • Patent number: 9004166
    Abstract: A gas separator for separating gas from a fluid in a production stream in a producing hydrocarbon well is described. The gas separator includes a central tube sized to fit into a well casing of the producing hydrocarbon well and having an input at its lower end for receiving the production stream and perforations at its upper end to allow the production stream to flow into the space between the central tube and the well casing. A suction tube is located inside the central tube, the suction tube is operable to draw fluid from the space between the central tube and the well casing and to deliver the fluid to an artificial lift mechanism.

  • Patent number: 8978753
    Abstract: A cyclonic strainer for a well intake that provides for improved separation of gas and fluid in naturally flowing wells during mechanical pumping operations. The strainer includes an elongated member having a channel formed longitudinally therein. A plurality of apertures extend through the elongated member angled downwardly into the channel and away from a center of the channel allowing for a better shear between gas and fluids. The angle of the ports causes fluid to be forced in an opposite direction, resulting in gases and fluids shearing more quickly and cleanly, due to kinetic energy. The angle of the ports can be varied to accommodate different conditions in various well environments. In well environments in which gaseous conditions are extreme, it can be desired for the ports to be sloped southwardly or downwardly at a greater angle than for well environments in which gaseous conditions are not as extreme.

  • Publication number: 20150068741
    Abstract: The disclosure is directed toward a downhole tool for separating fluids into a liquid and a gas component. The downhole tool includes an inlet for receiving a multiphase fluid, the multiphase fluid comprising a gas component and a liquid component. The tool also includes a hydrocyclone portion where the flow of the multiphase fluid is vortical and the liquid component migrates to an inner surface of the hydrocyclone portion and the gas component is forced to a central area of the hydrocyclone portion and exits the downhole tool via a gas outlet. The tool further includes a liquid outlet permitting the liquid component to exit the downhole tool.

  • Patent number: 8960283
    Abstract: An apparatus for use in launching cement plugs in a well cementing operation comprises a cylinder, a piston slideably received in the bore of the cylinder and an actuator extending from the piston through the cylinder. The actuator is operable by the piston for launching plugs from the apparatus into the well. A resilient damper cartridge is slideably mounted on the actuator in the cylinder so as to be contactable by the piston. A series of frangible pins is located in the cylinder wall so as to provide temporary limits to the movement of the cartridge in the cylinder as the piston slides along the cylinder.

  • Patent number: 8960282
    Abstract: A subterranean debris catcher takes in debris laden fluid at a lower end. The inlet flow is induced with an eductor whose discharge goes around the housing to the lower end inlet for the debris. The eductor suction induces flow into the lower end of the housing as well. Incoming debris goes up an annular space around the collection receptacle and turns to pass through a bladed wheel that imparts a spin to the flowing stream. The flow direction reverses from up before the wheel to down through a tube after the wheel. The solids are flung to the tube periphery and the fluid reverses direction to go back up to a screen before reaching the eductor suction connection. The debris swirls down an open bottom tube and is collected in a housing surrounding the down tube.

  • Patent number: 8936094
    Abstract: An example flow control device includes a body having an inlet and an outlet and a flow chamber extending therebetween. The flow chamber is configured to convey a fluid composition comprising a desired and an undesired fluid from the inlet to the outlet. A nozzle is arranged at the outlet and in fluid communication with the flow chamber, and at least one helical groove is defined along at least a portion of an axial length of the flow chamber. The at least one helical groove is configured to impart rotational motion to the fluid composition and thereby force at least some of the undesired fluid into the at least one helical groove and slow a progress of the undesired fluid along the axial length of the flow chamber.
