  • Patent number: 8371379
    Abstract: In accordance with some embodiments, a pumping station controller (14) is provided for monitoring pumping station hardware such as a well level sensor (8) and pumps (10a, . . . , 10n). A user interface (12) enables a user to input data to the controller (14) for controlling the operation of the pumps (10) based on the sensed liquid level. Pumping hardware configurations vary from site to site so that wiring the hardware to the controller may be confusing for the user. To address this problem the controller may comprise a software product (20). The software product may comprise instructions for processor (19) to determine a suitable wiring configuration between the controller (14) and the pumping station hardware, based upon user entered parameters identifying the pumping station hardware to be used.

    Abstract: A well watchman pumping and control system capable of operating in a wide range of ambient conditions is described. The system automatically maintains water level in a water storage vessel, while protecting the pump and generator from operating in conditions outside preset operating parameters to prevent premature failure and reduce repair. By operating to pump water only when preset operating conditions exist, e.g. low water level, ambient temperature, etc., the system reduces labor, fuel, and maintenance operating costs to the owner, improves well pumping reliability and production, reduces generator fuel consumption, reduces emissions, and conserves ground water.

  • Publication number: 20120318502
    Abstract: Methods and apparatus enable monitoring a hydrocarbon well for water within a flow stream of the well. A water detector includes a light source for emitting into a flow stream infrared light that includes a water absorbent wavelength band. A detector detects attenuation of the water absorbent wavelength band upon the infrared radiation passing through at least a portion of the flow stream. The water detector outputs a presence of water and/or a phase fraction or quantification of water as determined based on the attenuation. Detecting attenuation of a substantially transmissive wavelength band with respect to water simultaneously with detection of the attenuation of the water absorbent wavelength band can enable correction for non-wavelength dependent attenuation.

  • Patent number: 8206124
    Abstract: An oil-gas vapor collection, storage, and recovery system ensures that no air or oxygen leakage into the production tank occurs when gauging and/or emptying a tank. The system provides a constant reservoir-type storage system by utilizing a variable volume gas bag, expanding with a surge of gas from the separator and with minimal water column pressure from the plunger lift system, thereby containing the gas surge, but contracting with gas dissipation thus minimizing the compressor cycling, while accommodating rapid liquid and vapor influxes into the tank thus maintaining constant tank pressure. With expansion, the bag actuates a switch which activates a compressor, which, in turn, compresses the contained gas into the pipeline. Upon bag collapse, a switch is activated to turn off the compressor. Thus, the system provides constant storage tank pressure because the gas bag accommodates and controls variable gas volume.

    Abstract: An electrical submersible pump that regulates pump flow rate based on sensor measurements of the fluid is disclosed. The sensor measures a property of the fluid being processed. The sensor may be located at the intake, discharge or other area of the pump. The sensor measures the relative proportion of gas in the pumped liquid. The pump flow rate is adjusted to maintain a desired level for the gas in a production environment. The pump may be used to operate and control a seabed gas-liquid separation and centrifugal pump system.

  • Publication number: 20110236225
    Abstract: A system for changing a pump displacement configuration includes a blender that provides low-pressure fluid to a pump. The pump has a power end and fluid end, where the fluid end includes a number of plungers. The system includes an actuator that couples the power end with a selectable subset of the plungers. The system further includes a controller that selects a subset of the plungers according to a job pumping rate, a job pumping pressure, and/or a fluid end failure event indicator. The controller further commands the actuator to couple the selected subset of the plungers to the power end.

  • Patent number: 8006766
    Abstract: A method and apparatus for controlling a speed of a pump operating in a well. A first step involves monitoring a production flow rate of fluids produced from the well. A second step involves controlling the speed of the pump with reference to the production flow rate by increasing the speed of the pump when the production flow rate is rising and decreasing the speed of the pump when the production flow rate is declining.

  • Patent number: 7987074
    Abstract: Method for efficient processing of controlled source electromagnetic data, whereby Maxwell's equations are solved [107] by numerical techniques [109] such as finite difference or finite element in three dimensions for each source location and frequency of interest. The Reciprocity Principle is used [103] to reduce the number of computational source positions, and a multi-grid is used [105] for the computational grid to minimize the total number of cells yet properly treat the source singularity, which is essential to satisfying the conditions required for applicability of the Reciprocity Principle. An initial global resistivity model [101] is Fourier interpolated to the computational multi grids [106]. In inversion embodiments of the invention, Fourier prolongation is used to update [120] the global resistivity model based on optimization results from the multi-grids.

  • Patent number: 7963328
    Abstract: A process and system for release and recovery of methane from subterranean methane hydrate deposits in which heated CO2 is used to displace methane from the methane hydrate deposits and a portion of the displaced methane is routed to a combustion device proximate the deposit for combustion in-situ, generating heated CO2 which is introduced into the deposit, displacing additional methane, a portion of which is routed to the combustion device, thereby providing a substantially self-sustaining process. Portions of the displace methane not routed to the combustion device are captured for use elsewhere.

  • Patent number: 7950464
    Abstract: An improved multi-well control system (MWCS) has a centrally based multi-well controller (MWC) in communication with one or more slave controllers and one or more electronic flow measurement devices (EFMs) for instant data monitoring and control of individual wells. The system also provides for an application host sub-system (AHSS) in communication with the MWC for historical and instant data retention. The system is capable of assigning one or more wells to a group for allocation purposes and organizing groups dependent on production levels of individual wells. The MWC is capable of tracking gas volumes produced by each well independent of groupings and communicating such data to the AHSS. The MWC provides monitoring and tracking data from one or more EFM devices and assigns total flow volume to individual wells. The entire MWCS can result in the reduction of manpower and an increase in overall production efficiency.
