  • 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: 9664665
    Abstract: Methods are provided for reservoir analysis. In some embodiments, a reservoir may be analyzed by obtaining abundance ratios at a first measurement station and a second measurement station and determining an abundance ratio trend. Abundance ratios at a third measurement station may be obtained and plotted versus depth with the previously obtained abundance ratios. A change in the abundance ratio trend may be identified and result in further investigation of the reservoir. If the abundance ratio is unchanged, additional abundance ratios may be obtained and plotted versus depth to further evaluate the abundance ratio trend. Methods for reservoir analysis using fluid predictions with and without offset well information are also provided.

  • 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.

  • Patent number: 8978757
    Abstract: A remote actuation tool equipped with an intermediate volumetric mechanism for enhanced tool durability in high pressure differential downhole environments. Valve segments of the tool are actuated by power available due to a pressure differential between atmospheric and hydrostatic chambers of the tool. Yet, the intermediate volumetric mechanism, whether in the form of a discrete chamber or a hydraulic line system, minimizes stresses of the differential pressure on tool hydraulics. Thus, failure rates are substantially reduced. So, for example, the tool may be reliably employed in downhole environments which present differential pressures in excess of about 30,000 PSI.
