摘要： A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a first valve arrangement comprising a first valve member associated with the first port of the tubular body; and a second valve arrangement comprising a second valve member associated with the second port of the tubular body. The first valve arrangement and the second valve arrangement are configurable to lock in a first configuration with the tubular body, such that the first port is closed and the second port is closed; to lock in a second configuration with the tubular body, such that the first port is open and the second port is closed; and to lock in a third configuration with the tubular body, such that the first port is closed and the second port is open.

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： An actuation member for use in fracking operations, which immediately prior to fracking locates a sand screen at a desired location along a tubing liner and eliminates having to trip out the frac string prior to commencing production. The actuation member comprises a cylindrical hollow collet sleeve, with one or more radially-outwardly biased protuberances forming a unique profile which further matingly engages a corresponding mating profile on one of a plurality of sliding sleeve members in the tubular liner. A longitudinally-extending sand screen is provided, longitudinally slidable on the actuation member. A spring member, adapted to be forcibly compressed by the sand screen member when pressurized fluid is applied, and decompressed upon removal of pressurized fluid, is further provided on the actuation member.

摘要： A liner hanger running system including a liner hanger having a body including a wall defined by an outer surface and an inner surface. The body includes an opening that extends through the outer surface and the inner surface. A piston housing including a wall portion defined by an outer surface portion and an inner surface portion is spaced from the outer surface of the body to define a piston Chamber exposed to the opening. A piston is arranged in the piston chamber. A liner hanger running tool including a dog key extends into the opening and engages the piston. The dog key is selectively shiftable relative to the liner hanger to release the piston and expose the opening to a setting pressure.

摘要： A sand removal system configured to remove sand from a casing installed within a producing wellbore. The system utilizes a bottom hole assembly comprising a check valve sub and at least one sand removal tool. A swab cup installed within a vertical section the casing is used to create a pressure differential around the bottom hole assembly, causing fluid and sand to flow at a high velocity into the sand removal tool. The sand is caused to flow upstream where is later removed from the wellbore.

摘要： A method for characterizing a bond between a first tubular disposed in a borehole and a structure outside of the tubular, the method includes transmitting a signal into and through the first tubular using a signal transmitter conveyed through the borehole and detecting a return signal using a return signal receiver conveyed through the borehole to provide return signal information in a time domain. The method also includes transforming the return signal information in the time domain to return signal information in a frequency domain using a transform and determining a difference between the return signal information in the frequency domain and reference frequency domain return signal information. The method further includes characterizing the bond of the first tubular to the structure outside of the first tubular using the difference to provide a characterization of the bond.

摘要： A modular anti-rotation device for preventing rotation with respect to the central axis of a drilling tool in a borehole and for producing a notch in a borehole surface. The anti-rotation device includes an upper fixture portion and a lower fixture portion in axial alignment. The upper fixture portion and the lower fixture portion are connected by yoke assemblies. Each yoke assembly is connected to the fixture portion and fixture portion at one end, and forming an articulated joint of the upper yoke assembly and the lower yoke assembly at a distal end opposite the first end. A roller is connected at each joint, connecting the upper and lower yoke assemblies. The rollers engage vertically with a borehole surface, the rollers travelling axially, as a drill shaft penetrates into the borehole, the rollers simultaneously preventing radial movement of the anti-rotation device and prevent rotation with respect to the central axis of the borehole.

摘要： A liner and a method of setting the liner. The liner includes an outer tubular member, a hydraulic actuator on an outer surface of the outer tubular member for hydraulically setting a packer of the liner, and a hydraulic channel for directing fluid through the outer tubular member and into the hydraulic actuator to set the packer. The hydraulic channel has a first port at an inner surface of the outer tubular member and a second port at the outer surface of the outer tubular member at an axial location of the hydraulic actuator. The first port is at a different axial location of the outer tubular member than the second port. A fluid is pumped through the hydraulic channel into the hydraulic actuator to set the packer.
