  • Patent number: 10253589
    Abstract: Systems and methods for positioning tubular members within a subterranean well include inner and outer tubular members extending into the well. An adjustment ring assembly is located between the inner tubular member and the outer tubular member and has an outer ring and an inner ring. The outer ring circumscribes, and is rotatable relative to, the inner ring to adjust the radial offset between a central axis of the wellhead assembly and a central axis of the inner tubular member.

  • Patent number: 10094998
    Abstract: A structure for directly leading down the optical unit (OU) from the OPPC (optical phase conductor) cable, by the OU leading-down connector (2) invented recently, is used for separating the plastic-pipe OU from the OPPC cable installed on the tower, avoiding the splicing of fibers on the tower of the old technique. Therefore it is possible to assemble the OPPC cable (1), the OU leading-down connector (2), the preformed armor rod assembly (3), the first link fitting (4), the residual cable rack (5), the second link fitting (6), the insulator string (7) on the ground all together. Then the whole assemble can be erected on to the tower. Just as the conventional overhead power line construction. So it is simple and saving in work.

  • Patent number: 9938772
    Abstract: The disclosure provides a system and process for drilling a subterranean wellbore. An embodiment includes a bottom-hole assembly for a downhole mud motor that incorporates an information sub, such as a measurement-while-drilling or logging-while-drilling tool, at a location below, or down-hole from, the mud motor. The assembly also includes a micronized bit-to-bend length, or a length between a forward end of the assembly's bearing mandrel and a fixed bend in the assembly's housing, of less than or equal to forty inches. The combination of the forward-located information sub and micronized bit-to-bend length allow the driller to rely on real-time data relating to conditions adjacent to the drill bit/bottom of the wellbore and take that real-time drilling data into account in steering the bit along a planned wellbore trajectory. Other embodiments are also disclosed.

  • Patent number: 9303487
    Abstract: Materials are delivered within an expanded string before the string is subsequently compressively loaded such that the heat given off by the reaction of the delivered materials raises the fluid temperature in the recently expanded string to temperatures in a range of about 150-300 degrees Centigrade. The materials can be separated for delivery and then allowed to contact to initiate the reaction. Alternatively the materials can be delivered in separate conveyances for more immediate start of the exothermic reaction at the needed location or locations. To the extent there is curing cement about the expanded tubular, then the heat generated also reduces curing time to full setup of the sealing material. The applied heat counteracts or eliminates the Bauschinger effect.

  • Patent number: 9291015
    Abstract: Multiple sensors on a drill string can be utilized to perform equivalent circulation density (ECD) analysis. By utilizing multiple ones of the sensors, the pressure drop in each section of the wellbore can be classified. Additionally, the inclusion of multiple sensors in the drill string allows a wellbore to be sectioned into intervals bounded by any two sensors. Pressure events occurring in a single section of the wellbore bounded by any two sensors can be isolated and analyzed. The isolation can be achieved by subtracting the pressure measured on the shallower sensor from that measured on the deeper sensor.

  • Patent number: 9243470
    Abstract: A downhole system and related method, which may be used in an injection well for permitting removal, repair and or replacement of equipment installed in the well without unloading the formation in which the well is placed. The system generally includes an annulus sealing device, such as a packer, at least one valve, such as a flapper valve, a latching assembly and a rigid elongate member. The rigid elongate member may be connected to the latching assembly and serves the valve to open and close, or be permitted to open and close. The latching assembly serves to disconnect, and subsequently reconnect, equipment from the annular sealing device. Such release is accompanied by closure of the at least one valve and reconnection by opening of the at least one valve. The latching assembly has seals to prevent fluid from flowing around the latching assembly when the valve is open.

  • Patent number: 9243468
    Abstract: A tubular has an exterior sealing element disposed in a recess. A swage passes through the tubular to increase its drift dimension from a location above the seal to below the seal. The interior projection that initially defined the exterior wall recess where the seal is located is expanded to the new drift dimension of the balance of the tubular. Extending members that are initially embedded in the seal while extending from the tubular wall that defines the recess move out during the expansion to engage the surrounding tubular to act as extrusion barriers and to aid in the fixation of the seal while being able to penetrate the wall of the surrounding tubular in so doing.

  • Patent number: 9222340
    Abstract: A flow control assembly can be mechanically adjusted, rotationally or translationally, inside a tubing downhole between multiple positions by an intervening tool from the surface to change resistivity to flow through the flow control assembly. The positions among which the flow control assembly can be adjusted can include a closed position, a fully open position, and positions at which fluid experiences various resistances prior to flowing to an inner area of the tubing.
