    Abstract: A well structure for providing drinking water. The well structure includes slotted horizontal collectors connected laterally to a fitting connector. A well casing is connected to a top of the fitting connector. The fitting connector is positioned in a bottom of the well bore such that the horizontal collectors are perpendicular to groundwater flow. Crushed stones are deposited in a lower portion of the well bore and allow groundwater to flow down and into the slots of the horizontal collectors. A geotextile filter fabric is placed over the crushed-stone fill. A pump is placed in the well casing to pump the groundwater to the land surface. A loam soil fill is deposited over the geotextile filter fabric. A seal is placed around the well casing under the land surface.

    Abstract: A tubing hanger assembly includes a tubular outer tubing hanger member adapted to land in a bore of a wellhead. A tubular inner tubing hanger member is adapted to be secured to a string of production tubing and has an engaged position in a bore of the outer tubing hanger member. A retaining mechanism selectively allows the inner tubing hanger member to be lowered relative to the outer tubing hanger member, then selectively allowing the inner tubing hanger member to be returned back to the engaged position, to create tension in the string of production tubing. The retaining mechanism operates in response to rotational movement of the inner tubing hanger member while the outer tubing hanger member remains stationary with the wellhead.

  • Publication number: 20150068760
    Abstract: In a completion for producing methane the bottom hole assembly has a base pipe with porous media surrounding it for equalizing flow along the base pipe. A shape memory polymer foam surrounds the porous media. The borehole can be reamed to reduce produced methane velocities. Surrounding the shape memory polymer is an exterior layer of consolidated proppant or sand that can self-adhere and/or stick to the polymer foam. The proppant or sand can be circulated or squeezed into position although, circulation is preferred. The borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The bottom hole assembly helps in fluid flow equalization and protects the foam and layers below from high fluid velocities during production.

    Abstract: In order to overcome the need to remove each fracturing plug after a plug and perforate operation it is desirable to utilize a profile latch in conjunction with a coupling profile. By having a profile in each coupling or at least in predetermined couplings a tool such as a perforating assembly including a fracturing plug may be precisely placed. A profile in the couplings also provides a means to latch the perforating assembly or other tool securely to the casing without using slips. Such profiles typically provide for securing the tool or perforating assembly in one direction although a particular profile may secure the assembly in place in two directions. By securing the tool or perforating assembly in one direction only the tool may be easily relocated or removed from the casing.

  • Publication number: 20140209309
    Abstract: A method of servicing a wellbore within a subterranean formation comprising providing a first wellbore tubular positioned within a second wellbore tubular creating a tubular flowpath and an annular flowpath, wherein the tubular flowpath and the annular flowpath converge in a mixing zone within the wellbore, placing an annular fluid through the annular flowpath, placing a tubular fluid through the tubular flowpath, and contacting the annular fluid and the tubular fluid in the mixing zone to form a composite fluid, wherein the composite fluid comprises a base fluid component, a proppant component, a crosslinkable polymer component, a crosslinking agent component, and an optional buffering agent component and wherein the components of the composite fluid are apportioned between the annular fluid and the tubular fluid such that reaction of the components to form the composite fluid is inhibited until the components of the composite fluid mix within the mixing zone.

  • Patent number: 8789580
    Abstract: Systems and methods for providing a casing exit include a casing section having a generally cylindrical outer sleeve including a proximal end and a distal end. The outer sleeve may define an outer window extending between the proximal end and the distal end. A generally cylindrical inner sleeve may be received within the outer sleeve and may define an inner window. The inner sleeve may be moveable between a first position in which the inner window is misaligned with the outer window and the inner sleeve substantially closes the outer window, and a second position in which the inner window is aligned with the outer window. A deflector tool may be configured to engage the inner sleeve and move the inner sleeve from the first position to the second position.

  • Patent number: 8783366
    Abstract: A method for routing an electrical conductor through a sub-surface channel in substantially any suitable metallic article of manufacture includes friction stir welding a cap in a groove formed in a surface of the article so as to form the sub-surface channel. An electrical conductor is then routed through the channel. The channel may further include a substantially tubular conduit formed therein with the electrical conductor being routed through the conduit. The friction stir weld zone formed during friction stir welding is generally harder and more wear resistant that the article body.

  • Patent number: 8763701
    Abstract: A system for opening a window (320) in lateral wellbore construction. The system includes a window joint (300) that is operable to be interconnected within a casing string. The window joint (300) has a window (304) formed therein that is defined by at least one score line (306) that creates a preferentially weaken region within the window joint (300) enabling internal removal of the window (304) in a predictable manner without generating wellbore debris. A window removal tool (310) is operable to be run in the casing string. The window removal tool (310) is operably engagable with the window (304) such that actuation of the window removal tool (310) internally removes the window (304) from the window joint (300), thereby opening the window (320).

  • Patent number: 8752628
    Abstract: A fluid flow control device disposable in a bore can include channels that can direct fluid flow based on one or more properties of the fluid more robustly. The channels may include a side channel between two other channels. The side channel can allow fluid flow to affect fluid flowing in one of the channels. Devices according to some aspects can differentiate between fluids having close, but different, properties and direct the fluid accordingly. Examples of fluid properties based on which the device can direct fluid include fluid density, fluid velocity, fluid viscosity, and Reynolds number of the fluid flow.
