    Abstract: A one trip interventionless method for fracking multiple intervals incorporates a remotely operated passage isolation valve for each interval. A screen backed by a base pipe is provided to route screened production through a shutoff valve before the production reaches the passage in the completion assembly. The shutoff valve is remotely operated as well. The fracking port is associated with a pressure responsive operator such as a j-slot mechanism with a spring return. The j-slot mechanism is behind a rupture disc so that it remains unaffected while other operations are going on in the wellbore. The rupture discs are set at different pressures for the intervals involved. Sequentially, each fracked zone is isolated and the zone above is opened with breaking the rupture disc and applying predetermined number of pressure cycles. The screen valves are remotely operated as needed after the fracking to initiate production from one or more intervals.

Once the ball is injected into the pressure equalization section, the pressure equalization apparatus applies pressure, thereby causing the pressure of the pressure equalization section to increase until it reaches close to wellbore pressure. Once the pressures of the pressure equalization section and the wellbore are close, the atmosphere-to-pressure frac ball injection chamber and the frac ball are pushed through the second seal pack and into the wellbore, where the frac ball can be pumped downhole.

  • Patent number: 8936083
    Abstract: Methods of forming channels within propped fractures that are essentially free of proppants and more spacious than the interstitial spaces within traditional proppant packs. Specifically, various proppant-laden fluids may be placed within a fracture in a subterranean formation, the proppants in the proppant-laden fluids having at least two distinct ranges of density. Once placed inside the fracture, the proppants can settle, separate, and consolidate into at least two distinct permeable masses according to their densities. Consequently, the high-density and low-density proppants can separate and form separate proppant masses when the fracture closes on the proppants. Through this process, a highly conductive channel can form inside the fracture through which production fluids can flow.

  • Publication number: 20140238674
    Abstract: Methods of providing fluid loss control in a portion of a subterranean formation comprising: providing a treatment fluid comprising a base fluid and a plurality of seeds; introducing the treatment fluid into a portion of a subterranean formation penetrated by a well bore such that the seeds block openings in the subterranean formation to provide fluid loss control; and degrading the seeds over time within the subterranean formation. In some methods, the seeds are present in the treatment fluid in an amount of at least about 5 pounds per barrel. In addition, in some methods the seeds are preferably degradable.

  • Patent number: 8789596
    Abstract: Multiple zones of a subterranean formation penetrated by a multi-zoned completed well may be fractured by pumping into one or more zones an acidizing solution at or above the fracturing pressure of the subterranean formation. After fractures are created or enhanced in the formation, a displacement fluid is pumped into the formation to farther advance the acidizing solution into the fractures.

  • Patent number: 8776882
    Abstract: Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers.

  • Publication number: 20140190697
    Abstract: A method of use of single component resins to strengthen structural features in subterranean formations includes providing particulates, a carrier fluid, a curable resin and a latent curing agent. The curable resin is not cured by the latent curing agent at room temperature, standard pressure or neutral pH. The particulates are coated with the curable resin and the latent curing agent to create resin-coated particulates. A slurry of resin-coated particulates is created in the carrier fluid, and placed into a portion of a subterranean formation and allowing the latent curing agent to cure the curable resin to form cured, resin-coated particulates.

  • Patent number: 8739878
    Abstract: The method disclosed herein includes the introduction of proppant-free stage and a proppant laden stage into the wellbore and/or subterranean formation. The method increases the effective fracture width and enhances fracture conductivity within the formation. Either the proppant-free stage or the proppant laden stage contains a breaker. The other stage contains a viscosifying polymer or viscoelastic surfactant to which the breaker has affinity. The proppant-free stage may be introduced prior to introduction of the proppant laden stage into the wellbore and/or formation. Alternatively, the proppant laden stage may be introduced into the wellbore and/or formation prior to introduction of the proppant-free stage.
