  • Patent number: 9739905
    Abstract: A method for sensing a condition of a hydrocarbon reservoir from a subterranean well having a lined section with a liner and an unlined section includes attaching an electric current sensor to the liner proximate to a lower end of the lined section and a plurality of electromagnetic sources located along the unlined section. The electromagnetic sources are activated independently and the resulting current induced in the liner by each electromagnetic source is measured with the electric current sensor. These measurements can be inverted to determine the spatial distribution of the electric conductivity within the reservoir and its changes in time due to fluid substitution during production. Alternatively, a fast and robust method for interpretation of the data is presented for early detection and location of a possible water front approaching the production well.

  • Patent number: 9714549
    Abstract: Adjustable drill string housings are described for use in the directional drilling of wellbores, e.g. wellbores for hydrocarbon recovery wells. The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected.

    Abstract: Disclosed is a system and method for horizontal directional drilling (HDD). The system and method utilize predictive algorithms to both characterize the soil within the borehole and to quantify instability within the drillstring. The soil characteristics are represented by a soil coefficient (?) which relates the curvature of the borehole with the length of thrust of the drill rig as well as by comparison of thrust while thrusting with torque while drilling. The value of (?) is obtained by comparison of the historical orientation of the drilling head over the length of the borehole and the borehole shape as determined by an arbitrary navigation sensor. Drillstring instability is determined as a function of historical thrust and torque efficiencies and windup over the length of the borehole.

Magnetic-related values from the signals can be processed, relative to the tool, to determine a position of a conductive structure from which the signal was generated in response to current flowing on the conductive structure. Additional apparatus, systems, and methods are disclosed.

  • Patent number: 9334701
    Abstract: An improved downhole well control tool (“WCT”) allows for the control of in-situ fluid flow from a production well having one or more production zones. The WCT is installed in a tubing string in a zone to be controlled. A ported seal stem having an orifice of a size and shape to provide the desired choking is seated in the WCT using wireline tools to allow for the production of oil and/or gas. The WCT has an orientation sleeve that causes the seal stem to rotate and align the orifice with a port in the WCT. The seal stem may be removed to fully-open the port of WCT for injection operations, or a non-ported seal stem may be seated in the WCT to seal off the zone. WCTs of different diameters allow for multiple zones to be controlled.

  • Patent number: 9291738
    Abstract: A portable locator and method for establishing the location of the cable line in a region which includes at least one generally straight electrically conductive cable line extending across the region from which cable line a locating signal includes a first arrangement for measuring a local flux intensity of the locating signal at a first above ground point within the region with the portable locator in a particular orientation at the first above ground point. A second arrangement uses the local flux intensity to establish a cable line angular orientation which limits the possible directions to the cable line relative to the particular orientation of the portable locator at the above ground point. A third arrangement uses the measured local flux intensity to establish an actual direction of the cable line that is selected from the possible directions based on certain characteristics of the locating signal.

  • Patent number: 9243455
    Abstract: Methods allowing precise directional drilling are provided. Such methods include use of directional drilling equipment which include a drill string with a hollow bottom rod connected to a boring tool by means of an obtuse-angle connection piece or “bent sub”. In order to restore the verticality of the drilling a vertical borehole section (F) is formed and then a probe equipped with an inclinometer is lowered inside the bottom rod. The string may be rotated into four angular positions and the inclination values of the probe in each angular position are detected at the depth reached. The string is rotated so as to bring it into an angular position corresponding to the maximum inclination value detected. The string is moved so as to move the boring tool further downwards and the inclination of the probe is detected again in order to check that verticality has been reached.

  • Patent number: 9181791
    Abstract: Disclosed is a system and method for horizontal directional drilling (HDD). The system and method utilize predictive algorithms to both characterize the soil within the borehole and to quantify instability within the drillstring. The soil characteristics are represented by a soil coefficient (?), which relates the curvature of the borehole with the length of thrust of the drill rig as well as by comparison of thrust while thrusting with torque while drilling. The value of (?) is obtained by comparison of the historical orientation of the drilling head over the length of the borehole and the borehole shape as determined by an arbitrary navigation sensor. Drillstring instability is determined as a function of historical thrust and torque efficiencies and windup over the length of the borehole.

  • Patent number: 9068414
    Abstract: A hydraulically actuated setting tool has a plurality of pistons that move in tandem when unlocked. The pistons are initially in pressure balance to take a load off a single locking mechanism that retains all the pistons. The pistons move due to admission of hydrostatic and/or applied pressure from the annulus on one side of each piston with an opposite side exposed to atmospheric pressure. The locking member is exposed to the annulus and is located away from any atmospheric chambers associated with the pistons. In this manner the components can be made thicker to resist burst and collapse pressure and the loads on the locking member reduced due to initial piston pressure balance configuration. Depths of greater than 10,000 meters can be used due to one or more of the described design features.
