  • Patent number: 7841416
    Abstract: Presented is a subsurface safety valve in which the flapper mount, hard seat and spring housing have been integrated into a single assembly. To accommodate a “soft seat insert,” a special retainer soft seat ring and soft seat seal are provided. The soft seat seal fits over a conical protruding surface (hard seat) that surrounds the main bore of the safety valve on the bottom side of the spring housing. The retainer ring fits over the soft seat seal and holds it in place against the conical surface. Notches along the perimeter of an upper flanged end of the soft seat seal prevent gases, such as nitrogen, from becoming trapped behind the seal and potentially damaging it during a rapid decompression event. A gap between the upper flanged end of the soft seat seal and the lower spring housing allow the seal to move up and down the conical protruding surface as the flapper opens and closes, reducing compression of the seal and the risk of a compression set due to repeated opening and closing of the flapper.

  • Patent number: 7823648
    Abstract: The application discloses a valve, which may include either a safety valve or a storm surge choke valve or the like, to isolate a zone below a valve from a string of production tubing. Preferably, the valve includes a flow interruption surface assembly, such as a flapper valve or a ball valve, displaced by an operating conduit extending from a surface location to the valve through the inside of the production tubing. The application also discloses a bypass-conduit inside the production tubing to allow communication from a surface location to the production zone when the valve is in either an open or a closed location.

  • Patent number: 7798227
    Abstract: A production tubing comprising a liner is placed downhole in a wellbore. A fluid pill containing proppant is squeezed into the annulus between the formation and liner, thereby packing the proppant into the annulus, effectively isolating the annulus. The packed proppant is permeable to liquids but impermeable to fracturing proppants. After isolation of the annulus, the wellbore may be perforated using a resettable perforation assembly. Once perforating is complete, the wellbore is fractured. The presence of the packed proppant in the annulus generates resistance to the flow of fracturing fluid along the annulus, forcing the fracture to propagate down the perforation tunnels, while also allowing subsequent production fluids to be produced along the annulus.

  • Patent number: 7798235
    Abstract: A safety valve assembly comprises a valve body, a flapper mount, flapper and a hinge used to rotate the flapper in an opened or closed position. Torsional pins are mounted adjacent the flapper mount, each having ends which extend into the hinge and terminating adjacent each other at a location along the hinge. Torsional springs are circumferentially mounted around the torsional pins. Tabs extend from the torsional springs and contact an actuation member extending over the top of the flapper. As such, the torque created by the torsional springs is transferred to the actuation member via the tabs, thereby reducing the stress on the torsional springs.

  • Patent number: 7789147
    Abstract: A method of fracturing using deformable proppants minimizes proppant pack damage, without compromising the fracturing fluid's proppant transport properties during pumping, by use of deformable proppants. Selection of proppant is dependent upon the mechanical properties of the formation rock. The strength of the deformable proppant is dependent upon the modulus of the formation rock being treated such that the proppant is capable of providing, at the very least, a minimum level of conductivity in in-situ stress environments. The maximum elastic modulus of the deformable proppant is less than the minimum modulus of the formation rock which is being treated. The method is particularly applicable in fracturing operations of subterranean reservoirs such as those comprised primarily of coal, chalk, limestone, dolomite, shale, siltstone, diatomite, etc.

  • Patent number: 7775776
    Abstract: A single conduit lift pump is disclosed that only requires a single fluid conduit for both the driving fluid and the pumping action of the pump in a well bore. Fluid pressure communicated to the pump by the single fluid conduit drives the pump to load a resilient member. The fluid pressure is cycled off to allowing the lift of fluid by action of the resilient member upon the single fluid conduit. The single fluid conduit makes this pump suitable for downhole operations for the oil and gas production industries in wells that have substantial water cut that inhibits the production of gas.

  • Patent number: 7772163
    Abstract: Well treating composites are composed of an organic lightweight material and a weight modifying agent. The organic lightweight material preferably forms the continuous phase and the weight modifying agent forms the discontinuous phase. The apparent specific gravity (ASG) of the organic lightweight material is less than the ASG of the well treating composite. The composite of the invention is particularly useful in hydraulic fracturing fluids as lightweight proppants as well as in sand control methods, such as gravel packing and frac packing A subterranean formation may be treated by injecting the well treating composite into the formation in order to increase fracture conductivity, reduce the generation of fines, reduced unwanted water production and/or reduce particulate production.

  • Patent number: 7766086
    Abstract: A downhole device used to divert fluid flow out of a work string into an annulus. The downhole device is activated by the movement of a plurality of pistons within the downhole device. Fluid flow through a restriction of the downhole device creates an increase in fluid pressure causing the movement of the pistons. The pistons move a flow tube between various locations within the device. In one location, the flow tube prevents fluid flow to the annulus while in another location the flow tube allows fluid flow to be diverted into the annulus. The downhole device may include a locating sleeve having a continuous j-track allowing the flow tube to be selectively retained at the various locations within the downhole device. Fluid flow through the downhole is used to cycle the device between diverting fluid flow to the annulus and forcing fluid flow down the work string.
