  • Patent number: 10746582
    Abstract: Provided is a tool-body that arranges ultrasonic and electrical capacitance sensors at close distances to the casing wall of the wellbore such that properties of thickness, flow velocity, acoustic impedance and the dielectric constant of the liquid layer are measured at a number of circumferential locations inside the casing of the wellbore. These measured values may then be combined to derive the average flow rate of the layer and also used to identify whether the liquid is water or condensate/oil, or a mixture of the two with a certain water-in-liquid ratio. Combined with a gas flow rate and a liquid droplets concentration measurement, the total liquid flow rate and liquid type can be derived.

  • Patent number: 9938789
    Abstract: A ball is retained behind a circular array of collet fingers to be pushed out through the collets with a spring biased piston that is initially locked when run in the hole. The lock mechanism is a link that holds a potential force in the main spring. One end of the link is held by an acceleration or deceleration responsive retainer. The retainer has a conforming stop surface to a stop surface on the link. Sudden relative movement caused by acceleration of the housing allows the retainer that is flanked by opposed springs to move away from the stop surface or surfaces on the link. The link is an array of spaced fingers that can radially flex. The radial flexing combines with the power of the main spring to propel the piston against the ball for a release of the ball. A fracturing operation then ensues.

  • Patent number: 9784069
    Abstract: A hydraulically actuated tubing drain for service with oil wells, water wells, gas wells and/or thermal wells has a configuration of structural features which, upon hydraulically opening the drain, prevent any debris from the rupture disk from entering either the tubing or the tubing-casing annulus. The disk housing and flow diffuser of the present invention mate directly together, capturing between the disk housing and flow diffuser a shoulder of the mandrel. This design eliminates the need for a threaded aperture through the side wall of the mandrel and the need for elastomeric seals.

  • Patent number: 9715024
    Abstract: A disclosed downhole telemetry system employs an array of near-field electromagnetic communication devices to relay information along a tubular in a borehole. In some embodiments, the devices are permanently attached to pipe joints without requiring any structural modification of the pipe joints. As the pipe joints are strung together in the normal fashion to form a tubular, the devices automatically establish a wireless communications path between an uphole terminus device and any downhole sensors or tools. The devices can include built-in sensors to provide distributed sensing of parameters such as temperature and pressure. In some embodiments the device array incorporates redundancy to minimize the chance of a communications network failure. The device array has applications for logging-while-drilling, production testing, well completion, reservoir monitoring, and well control.

  • Patent number: 9618427
    Abstract: The disclosure describes a system to segregate, enrich and capture oil, water and gas samples from a multiphase flow. The system can be used in a subsea location, on the surface or in any other condition where it is connected to a flow of different phases of gas and/or liquid. The samples obtained are representative in composition of the phases flowing at well head conditions in terms of both pressure and temperature. Additionally, a relatively small volume of each phase is used in obtaining the samples. The system connects and disconnects to ports installed at the sampling location nearby the wellhead or the production line. The sampling flow is controlled by means of a pump. The collected samples are separated in mono (or nearly mono)—phase samples (oil, water and gas) and stored in individual bottles.

  • Patent number: 9441420
    Abstract: A lateral wellbore is formed from a high side of a horizontal portion of a primary wellbore with a drill bit assembly that has a selectively extendable pilot bit. The drill bit assembly is mounted on a lower end of a drill string. A bit guide is disposed adjacent the drill bit assembly for urging the drill bit assembly in a lateral direction against the high side of the primary wellbore. Rotating the drill bit assembly while urging the drill bit assembly upward creates a groove in a subterranean formation adjacent the primary wellbore. This forms a ledge at a far end of the groove. The drill string is then drawn back from the groove, and the pilot bit is deployed. Urging the drill bit assembly forward engages the pilot bit with the ledge, providing leverage for retaining the drill bit assembly in an orientation for excavating the lateral wellbore.
