  • Patent number: 9765578
    Abstract: A sanitary check valve arranged between a drop and outlet pipes in a water well casing that will prevent operate to block a back flow of water through the drop pipe when pumping from a water source is discontinued as could contaminate that water source. The valve is for fitting into an actuator fitting body that mounts between the drop and outlet pipes opposite ends and includes a side plate for releasable coupling to a separate actuator mount that connects through the well casing and includes a drain pipe. The drop and outlet pipes fitted to the fitting body are lowered into the well casing to where the side plate edges slid between parallel sides of the mount, coupling the assembly together such that an upward water flow moves the float valve off of the drop pipe end to pass that flow through the outlet pipe for use, and, when that upward flow is stopped, the valve closes over the drop pipe end and opens to the mount drain pipe to a water flow that dumps outside the well casing.

  • Patent number: 9297247
    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.

    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.

  • 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.

  • Publication number: 20140352950
    Abstract: The present invention relates to a method for controlling a drilling or cutting operation performed by a wireline tool downhole, comprising the steps of commencing a drilling or cutting operation in a downhole object, such as a casing or valve; detecting vibration produced during the drilling or cutting operation in the downhole object using a vibration sensor adapted to transmit detected vibrations; processing a vibration signal from the vibration sensor to produce a real-time frequency spectrum; comparing the frequency spectrum to a reference frequency spectrum; and controlling the operation based upon the comparison of the frequency spectrum and the frequency spectrum specification. Furthermore, the present invention relates to a wireline tool for performing a drilling or cutting operation downhole and carrying out the method according to the invention.

  • Patent number: 8898046
    Abstract: A method for modeling flow properties over a series of time increments of a reservoir in an earth formation having a plurality of fractures is disclosed. The method includes: building a three-dimensional stress field representing stresses in the reservoir; building a three-dimensional discrete fracture network (NFM) having fracture flow properties using information obtained from a tool or changes to the stress field; running a flow simulation of the reservoir for a time increment using the NFM to model the flow properties of the reservoir for that time increment; computing a latest change in the three-dimensional stress field from the flow simulation; and incrementing the time increment and iterating the building the NFM using the latest change in the stress field, the running of the flow simulation using the latest NFM, and the computing a latest change in the stress field from the latest running of the flow simulation.

  • Publication number: 20140332199
    Abstract: Tunable down-hole stimulation systems feature closed-loop control of pumps and tunable down-hole stimulators. Stimulators generate and hydraulically transmit broad vibration spectra tuned for resonance excitation and fracturing of geologic materials adjacent to the wellbore. Feedback data for controlling stimulation includes backscatter vibration originating in stimulated geologic material and detected at the stimulator(s). For initial fracturing with relatively large particle sizes, the power spectral density (PSD) of each stimulator output is down-shifted toward the lower resonant frequencies of large particles. As fracturing proceeds to smaller (proppant-sized) fragments having higher resonant frequencies, backscatter vibration guides progressive up-shifting of stimulator PSD to higher vibration frequencies. Stimulator power requirements are minimized by concentrating vibration energy efficiently in frequency bands to which geologic materials are most sensitive at every stage of stimulation.

  • Patent number: 8881798
    Abstract: A subterranean tool that is self contained for actuation can be run into a desired location on an automatic set mode controlled by a timer. If a problem develops in getting the tool to the desired location in time a magnetic field created by permanent or electro-magnets can be brought to bear on the tool to stop the timer before the tool actuates. Once the tool is subsequently positioned at the desired location another magnetic field can be brought to bear near the tool to set it. Alternatively, the tool can be run to the desired location without activation with the timer and then the magnetic field can be brought to the tool to set it. The magnetic field can be lowered to the tool with wireline or can be dropped or pumped past the tool to actuate the tool. Optionally the field can be generated from within an object that ultimately lands on a seat to provide a backup way to set the tool using tubing pressure.

  • Publication number: 20140318761
    Abstract: A hydrostatically set packer is held against setting by a locking member that is made of controlled electrolytic material (CEM). After introduction into a wellbore and exposure to thermal or well fluid inputs the lock made of CEM dissolves or is otherwise weakened to the point where relative movement can occur for the setting of the packer with available hydrostatic pressure. The locking member can also be a shape memory alloy at least in part whose shape change allows the tool to set.
