  • Patent number: 10787797
    Abstract: An odor venting water pump system uses an air pump to agitate well water within a well enclosure in order to separate unpleasant smelling gases from the well water. A water pump is positioned at the bottom of a well enclosure and surrounded by well water received into the well enclosure from the surrounding ground water supply. An air tube is connected to an air pump and a terminal end of the air tube is positioned at the lower end of a venting pipe which has an inlet to accept well water. The pumped air agitates the water within the venting pipe and pushes the air/water mixture upwards through the venting pipe to an outlet, where the water returns to the main water supply while the odious gases are free to exit the well enclosure through an air vent at the upper end of the well enclosure.

  • Patent number: 9915134
    Abstract: An integrated system is disclosed to handle production of multiphase fluid consisting of oil, gas and water. The production stream is first separated into two streams: a liquid dominated stream (GVF<5% for example) and a gas dominated stream (GVF>95% for example). The separation can be done through shrouds, cylindrical cyclonic, gravity, in-line or the like separation techniques. The two streams are then routed separately to pumps which pump dissimilar fluids, such as a liquid pump and a gas compressor, and subsequently recombined. Both pumps are driven by a single motor shaft which includes an internal passageway associated with one of the pumps for reception of the fluid from the other pump, thereby providing better cooling and greater overall efficiency of all systems associated therewith. A method for providing artificial lift or pressure boosting of multiphase fluid is also disclosed.

  • Patent number: 9687759
    Abstract: The invention relates to an apparatus for cyclone separation of a fluid flow into essentially a gas phase fraction and a liquid phase fraction, by bringing the fluid flow into rotation so that said fluid flow is separated into a central zone essentially containing the gas phase fraction, and an outer annular zone essentially containing the liquid phase fraction, comprising: a housing (2); a swirl element (6) for rotation of the fluid; a gas phase outlet (5); and a liquid phase outlet (4); whereby the gas phase outlet and the liquid phase outlet both connect to a common collecting chamber outside the housing. The invention also relates to a vessel provided with at least one such apparatus.

  • Patent number: 9670758
    Abstract: A centrifugal well fluid pump has a pump intake and a pump discharge conduit extending upward from the pump. A barrier between the motor and the pump intake seals to casing in a well. A bypass tube extends from below the barrier, alongside the pump and has an outlet at an upper end of the pump. A riser surrounds the pump discharge conduit, the riser having a riser inlet in fluid communication with the bypass tube outlet. Liquid portions of the well fluid flow upward through the riser to discharge from the riser outlet and flow down to the pump intake. Gaseous portions of the well fluid flow upward through the riser and continue flowing upward into the casing.

  • Patent number: 9638014
    Abstract: A well pump assembly includes rotary pump and a submersible motor. A shroud surrounds the pump intake and the motor. The shroud has an open upper end in fluid communication with the pump intake for drawing well fluid along an upper flow path down the shroud into the pump intake. A dip tube is secured to and extends downward from a junction with a lower end of the shroud. The dip tube is in fluid communication with the pump intake and has an open lower end for drawing well fluid along a lower flow path up the dip tube to the pump intake. The upper flow path has a minimum flow area that is smaller than a minimum flow area of the lower flow path. The dip tube has a smaller outer diameter than an outer diameter of the shroud.

  • Patent number: 9617822
    Abstract: A setting assembly for a packer seal features peripherally mounted rod pistons that abut the seal to be set by advancing the seal relative to a tapered surface. When parts of the seal engage an inner tubular wall before other parts of the seal the continuation of application of hydraulic pressure to the pistons moves parts of the seal that have yet to make contact with the tubular wall further relative to the ramp so that plastic deformation of the seal assembly can occur to allow portions thereof to move radially further outwardly to seal in the region where the radius of the tubular is enlarged. When hydraulic pressure is applied to the pistons in an opposite direction a lock mechanism is defeated and the c-ring or scroll reverts to a smaller shape optionally aided by a garter spring so that the packer can be selectively retrieved.

  • Patent number: 9545598
    Abstract: An absorber is provided which uses a liquid solvent formed into a myriad of bubbles and micro-droplets. The solvent froth is a solvent for a selected component in an incoming gas stream. A plurality of spaced apart mesh assemblies is placed in one or more absorber tubes or in a reaction vessel. Using screens having cross-sections that are substantially rectangular wave in design together with proper operating parameters, the phenomenon of solvent pulsing is induced and maintained, maximizing efficiency of the absorber.

  • Patent number: 9534603
    Abstract: An apparatus and system for a thrust-absorbing horizontal surface pump assembly is described. A thrust-absorbing horizontal surface pump system includes an intake chamber including a stationary thrust bearing paired with a rotatable thrust runner to form a thrust bearing set, wherein a first face of the stationary thrust bearing positioned towards the rotatable thrust runner is at least partially diamond-coated, and wherein a second face of the rotatable thrust runner positioned towards the stationary thrust bearing is at least partially diamond-coated, a fluid entrance that receives a fluid into the intake chamber, and a pump inlet that receives the fluid into the multi-stage centrifugal pump, wherein the thrust bearing set is arranged around the intake shaft such that during operation of the electric motor the thrust bearing is in a pathway of the fluid as the fluid flows between the fluid entrance and the pump inlet.

  • Patent number: 9518458
    Abstract: A gas separator assembly generates an artificial sump in a production casing receiving a production tubing string with a downhole pump at the bottom end thereof. The assembly includes an inner casing in series with the production casing of the well and an outer casing supported externally of the inner casing. First and second ports at opposing top and bottom ends of the outer casing communicate from a primary passage in the inner casing to a secondary passage between the inner and outer casings. A barrier supported in the primary passage between the first and second ports diverts flow through the secondary passage and effectively defines the sump area in the primary passage between an inlet of the downhole pump adjacent the barrier and the first port thereabove.

  • Patent number: 9388679
    Abstract: A gas separator connectable to a pump for flowing production fluid, the separator having a housing defining an internal cavity with an inlet end defining for the production fluid. A housing first pumping stage pressurizes the production fluid, and a first fluid flow restrictor downstream of the first pumping stage limits the production fluid to a selected first flow rate. A first separation chamber in the housing downstream of the first fluid flow restrictor separates some gas from the production fluid, and a housing second pumping stage further pressurizes the production. A second fluid flow restrictor downstream of the second pumping stage limits the production fluid flow to a selected second flow rate, and a second separation chamber downstream to the second fluid flow restrictor effects further gas separation from the production fluid.
