    Abstract: An example method includes introducing a solution into at least part of a reservoir. The solution includes a contrast agent and a fluid. The contrast agent includes a polymer having a dielectric constant that may be greater than a predefined value. The example method also includes using at least one EM transmitter antenna to direct a first electromagnetic (EM) signal into the reservoir. The first EM signal passes through the at least part of the reservoir into which the solution was introduced. The first EM signal is received using at least one EM receiver antenna following passage through the at least part of the reservoir. Data is determined that represents a difference between a first travel time of the first EM signal transmitted through the contrast agent in the reservoir and a second travel time of a second EM signal transmitted through water-saturated reservoir rock. Information about a physical feature of the at least part of the reservoir is generated based on the data.

  • Patent number: 10145212
    Abstract: A system and method for providing artificial lift to production fluids within a subterranean well includes loading an electrical submersible pump assembly into an interior cavity of a pump launcher. The electrical submersible pump assembly has a motor and a pump. The pump launcher is releasably secured to a wellhead so that the interior cavity is in fluid communication with an inner bore of a production tubing that extends a length into the subterranean well. A propulsion system is activated to move the electrical submersible pump assembly from the pump launcher and into the subterranean well, wherein the propulsion system includes a self-powered robotic system having a propulsion mechanism. The propulsion system can be communicated with to control the descent of the electrical submersible pump assembly through the subterranean well.

  • Patent number: 10113549
    Abstract: A method for monitoring an electric submersible pump. The method includes acquiring a baseline signature for the electric submersible pump in a first environment, acquiring a downhole signature for the electric submersible pump in a downhole environment while the electric submersible pump is confirmed to be healthy, applying an operator to the baseline signature and the downhole signature that results in a downhole noise component, acquiring a vibration signature for the electric submersible pump in the downhole environment while the electric submersible pump is in an operating mode, removing the downhole noise component from the vibration signature to produce an isolated electric submersible pump signature, and determining a health status of the electric submersible pump based on the isolated electric submersible pump signature.

  • Patent number: 10036231
    Abstract: A flow control method and assembly for an oil or gas well comprises generating a pressure signature in the fluid in a bore of the well comprising a minimum rate of change of pressure, and transmitting the pressure signature to a control mechanism to trigger a change in the configuration of a flow control device in the bore in response to the detection of the pressure signature in the fluid. The flow control device can comprise a barrier, such as a flapper, sleeve, valve or similar. The pressure signature is transmitted via fluid flowing in the bore, typically being injected into the well, optionally during or before frac operations, via fluid being used for the frac operations. The control mechanism typically includes an RFID reader to receive RF signals from tags deployed in the fluid flowing in the bore.

  • Patent number: 10030508
    Abstract: Evaluating annulus-tubing communication points in a production well having an annulus between a production string and a surrounding string(s) of casing. Determining a composition of production fluids produced from the well, and injecting one or more tracer materials into the annulus of the well under pressure as part of a lift gas. Each of the one or more tracer materials defines a material that is not native to the production fluids, and each has a different rate of diffusivity in the lift gas. The tracer materials are detected upon being produced at the surface. A mass spectrometer or other analyzer capable of detecting tracer materials at concentrations of less than 1,000 ppm is used. Determining injection points of the one or more tracer materials, and determining whether each of the injection points represents a gas lift valve along the production tubing.

    Abstract: A system, method and apparatus for autonomous data collection from variable frequency drives (VFD) is described. The system includes at least two embedded control systems, each built on a commercial platform, with customized components in transportable cases. A computer program with multiple instantiations operates on the at least two embedded control systems to provide a client-server implementation of data collection and recording units. The units communicate by Wi-Fi autonomously when the client comes within range of the server. Units do not require any direct intervention by technicians to gather and store VFD system data. The client is a mobile unit is installed in a field truck operated by a driver without the training to operate a VFD. When the mobile unit obtains a communications link to a central receiving server, the unit uploads its data for processing in a processing system.
