  • Patent number: 9938803
    Abstract: A method for controlling the liquid load size of a plunger lift well during the shut in time of the well to facilitate a controlled plunger rise. Intra-cycle control allows dynamic adjustments within a cycle to keep the plunger running and not stalling out or rising too fast. The method includes the steps of shutting in the well to build up pressure within the well, adjusting a size of a liquid slug within the tubing while the well is shut in, opening a valve to relieve pressure within the well and raise the plunger within the tubing, pushing the liquid slug out of the well with the plunger, and closing the valve wherein the plunger falls within the tubing. The intra-cycle adjustments include reducing the size of the liquid slug for preventing fluid loading and increasing the size of the liquid slug for controlling a rise rate of the plunger.

  • Patent number: 9291033
    Abstract: Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly.

  • Publication number: 20150047835
    Abstract: The present disclosure relates to determining hydrogen indexes of downhole fluids using fluid composition data. In certain embodiments, the type of the fluid, such as gas, water, or oil, may be determined downhole and used to select a method for determining the hydrogen index of the fluid. The selected method may then be employed while the tool is downhole to calculate the hydrogen index of the fluid.

  • Publication number: 20150021018
    Abstract: Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear.

  • Publication number: 20150013973
    Abstract: A method for routing a fluid within a flowline of a downhole tool is provided. In one embodiment, the method includes moving a piston within a chamber of a downhole tool to push a fluid out of the chamber and into a flowline. The method also includes using a pump in the downhole tool and in fluid communication with the flowline to route the fluid within the downhole tool via the flowline while moving the piston within the chamber. Additional systems, devices, and methods are also disclosed.

  • Publication number: 20150013968
    Abstract: A method includes pumping fluid from outside of a downhole tool through a flowline of the downhole tool with a pump and taking first measurements, using at least one sensor, within the flowline during a first stage of pumping the fluid. The method further includes estimating a saturation pressure of the fluid, via a processor, based on the first measurements and a saturation pressure model generated based on second measurements taken using the at least one sensor during a second stage of pumping the fluid, and operating the pump to maintain a fluid pressure in the flowline greater than the estimated saturation pressure.

  • Patent number: 8931570
    Abstract: An apparatus for controlling fluid in-flow into a wellbore tubular includes a translating flow control element having one or more fluid conveying conduits; and a reactive element that actuates the flow control element. The reactive element may be responsive to a change in composition of the in-flowing fluid. The reactive element may change volume or shape when exposed to or not exposed to a selected fluid. The selected fluid may be oil, water, or some other fluid (e.g., liquid, gas, mixture, etc.). The reactive element may slide the flow control element such that a conduit formed on the flow control element changes length, which then changes a pressure differential across the flow control element.

  • Publication number: 20140374089
    Abstract: A system for pump down operations includes a diversion valve unit that is adjustable between a pumping position and a diversion position and a controller coupled to the diversion valve unit. The system further includes a fluid reservoir, a downhole fluid path between the fluid reservoir and a tool downhole, a driving unit in the downhole fluid path for advancing the tool, and a diversion fluid path between a portion of the downhole fluid path downstream of the driving unit and the fluid reservoir or another fluid receptacle. The diversion valve is in the diversion fluid path and the controller automates the diversion valve position for the diversion valve unit based on a monitored wireline speed or a monitored wireline tension for a wireline unit.

  • Publication number: 20140374090
    Abstract: The invention relates to an apparatus and a method for opening and closing an automatic valve installed in the discharge line of an oil well, characterized by the installation and setup of the apparatus which controls an automatic valve, which is installed in the discharge line of the casing pipes of an oil well. In said oil well a progressive cavity pump system (PCP) has been installed, which pumps the hydrocarbon to the storage tank through the production pipe, said system maintaining the level of hydrocarbon inside the well for improved production. The apparatus to be installed in the oil well consists of three pressure transmitters, which are placed in the discharge lines of the production pipes, casing pipes and in the discharge line going into the storage tank near the well. In addition, in the storage tank, a radar-type level transmitter is installed to keep monitoring the production from the oil well.

  • Patent number: 8910710
    Abstract: A method, software, and apparatus for controlling a pump configured to pump liquid out of a well. Such control may involve determining whether a production rate of gas from the well is increasing, decreasing, or steady, and whether to switch the pump between an OFF state and an ON state. Whether the pump is switched may depend upon whether the production rate of the gas is determined to be increasing, decreasing, or steady.
