  • Patent number: 7273105
    Abstract: A system is described for monitoring a subsea formation, which is under development. Instruments located in a completed but unconnected well are employed for providing information by a provisional monitoring unit being lowered downhole and connected to the well. Changes in the reservoir as a result of operations in other adjacent wells are intercepted by the instruments in the well and transmitted via an acoustic link to the surface.

  • Patent number: 7117891
    Abstract: The invention is directed to a pressure bleed device for a hydraulic coupling which includes a male component that comprises a body, a flow passage which extends generally axially through the body, a valve seat which is formed proximate one end of the flow passage, and a valve element which is biased into sealing engagement with the valve seat to thereby close the flow passage. The pressure bleed device includes a bleed passage which extends through the body and communicates with the flow passage, and a valve for selectively opening the bleed passage when an internal pressure within the flow passage is greater than an external pressure outside the body. Thus, when the flow passage is closed, excess internal pressure within the flow passage is vented outside the body through the bleed passage.

  • Patent number: 7114571
    Abstract: A running string for a subsea completion comprises an upper section (70) which may be a coiled tubing (CT) injector unit as shown, or a wireline lubricator (FIG. 8). A lower section (60) provides wireline/CT access to production/annulus bores of a tubing hanger (not shown) attached to tubing hanger running tool (62). A flow package (64) in the lower section (60), together with BOP pipe rams (86) and annular seal (88), directs production and annulus fluid flows/pressures to the BOP choke/kill lines (78/76). The upper and lower sections allow installation and pressure/circulation testing of, and wireline/CT access to, a subsea completion, without the use of a high pressure riser.

  • Patent number: 7104394
    Abstract: A conveying apparatus comprises an elongated conveying bed which includes a proximal end and a distal end. A support structure for the conveying bed accommodates vibratory motion of a portion of the conveying bed extending from the proximal end a substantial distance toward the distal end but dampens vibratory motion at the distal end. In addition, a piezoelectric driver is operatively connected to the conveying bed adjacent the proximal end. Consequently, operation of the piezoelectric driver will induce a wave motion in the conveying bed which will effectively convey a material from the proximal end to the distal end.

  • Patent number: 7013970
    Abstract: A completion system comprises a christmas tree (10) mounted on a wellhead housing (11), a tubing hanger (12) landed in the tree or wellhead housing, the wellhead housing (11) being mounted on a casing string (100) and a tubing string (14) being suspended from the tubing hanger within the casing string; wherein, in use, the annulus defined between the tubing (14) and the casing (100) serves as a production bore. A second tubing string (98) is expanded into sealing engagement with the casing string (100) over at least a portion of their lengths. The annulus normally used to provide well service functions is thus eliminated. Well servicing is instead provided via the tubing string (14), which may be coiled tubing.
