    摘要: A multi-zone, one trip completion system for a wellbore is described. A plurality of isolation packers is installed in borehole to isolate a plurality of zones of the annulus between a tubing string and a wellbore. Each tubing string section is positioned in a zone and comprises a selectively openable stimulation port to provide stimulation fluid to its zone and a selectively openable production port to receive fluid from its zone. The system also comprises a circulation system with a plurality of circulation tubes and circulation tube valves, being configurable in a plurality of configurations to selectively connect, via a circulation flow path, the central bore or the borehole annulus of a wellbore at each of the plurality of sections, to an upper circulation flow path open to an annulus above an uppermost of the plurality of isolation packers.

    摘要: A method of drilling an uncompleted lateral wellbore in a subsurface formation includes drilling the uncompleted lateral wellbore with coiled tubing in the subsurface formation. The subsurface formation includes unconsolidated sand and the subsurface formation overlays a water-saturated reservoir. The method may further include introducing particles having an average particle size of from 8 mesh to 140 mesh into the uncompleted lateral wellbore, thereby supporting the uncompleted lateral wellbore and avoiding wellbore collapse and installing a screen in a vertical wellbore fluidly connected to the uncompleted lateral wellbore, wherein the screen has a mesh size of from 325 mesh to 1000 mesh. The subsurface formation may include hydrocarbons and the method may further include producing hydrocarbons from the subsurface formation.

    摘要: A method for fracking a hydrocarbon formation. An actuating member, flowable along a production string, is provided. A unique key portion thereon engages a desired sliding sleeve covering an associated port in the production string. Applying uphole fluid pressure causes the sliding sleeve and actuating member to move so as to uncover the associated port. After fracking and cessation of supply of pressurized fracturing fluid, a compressed spring on the actuating member decompresses so as to reposition a sand screen immediately beneath the port so as to prevent sand from flowing into the production string. Flowable insertion of additional “keyed” actuating members allows similar opening of additional successive uphole ports and fracking in the regions of such additional opened ports, with similar location of sand screens at each opened port. Plug members on each actuating member thereafter dissolve or are successively burst to thereby allow production.

    摘要: A method and apparatus for separating of gas from liquids in a wellbore, the apparatus enabling the receiving of wellbore fluids into two or more production separation chambers, operating in parallel. The apparatus further enabling the receiving of production separation chamber fluids into a production pipe through a thief jet port disposed in a lower chamber beneath the production separation chambers. The apparatus further enabling extraction of bottom hole gas fluids in the wellbore from under the two or more production separation chambers and disposing the gas fluids back into the wellbore above the two or more production separation chambers.

    摘要: An example liner hanger system includes a casing for lining a wellbore and a collar configured for connection to a part of the casing within the wellbore. The collar has a first shape and a liner hanger has a second shape that is based on the first shape. The liner hanger is configured to fit within, and to be supported by, the collar. The system also includes a screen connected to the liner hanger.
