With Explosive Or Gas Generating Means In Well Patents (Class 166/63)
  • Patent number: 11352847
    Abstract: A downhole chemical reactor can be placed in a downhole environment to generate gas in-situ. This gas can pressurize an inner pressure chamber of the downhole chemical reactor to create a pressure-on-demand source or to maintain a constant pressure reservoir, depending on the configuration of a reactor controller coupled to an inlet of the inner pressure chamber. The inner pressure chamber contains one or more desired chemical reactants and the reactor controller operates to permit well fluid to flow from the wellbore and into the inner pressure chamber. The well fluid reacts with the desired chemical reactants and generates one or more gases such as hydrogen or carbon dioxide. The generated gases pressurize the inner pressure chamber and a pressure regulator coupled to the inner pressure chamber maintains a maximum pressurization of the inner pressure chamber. For a constant pressure reservoir, the reactor controller repeats this cycle indefinitely.

  • Patent number: 11280143
    Abstract: A wireline conveyed, gas driven setting tool configured to set downhole tools including, without limitation, frac plugs, bridge plugs, cement retainers and packers. The setting tool is functioned by selectively igniting a power charge inside of a firing head. As the power charge burns, it generates gas that acts upon a piston area to stroke the setting tool. A dampening media, as well an optimized flow area at or near the distal end of the setting tool, act to slow the setting stroke.

  • Patent number: 11131162
    Abstract: A frac plug system, downhole tool and method of securing a frac plug system in a wellbore in a formation. A mandrel includes a first end and a second end. A setting assembly is coupled to the mandrel at the first end, and an anchor is arranged at the second end of the mandrel and receptive to the setting assembly. The anchor is settable to engage the wellbore. A bottom sub is arranged at the second end of the mandrel and includes a first member movable relative to the mandrel. A gas generates a pressure to shift the first member along the mandrel to move the anchor against the setting assembly, securing the setting assembly in the wellbore via radial deployment of the anchor.

  • Patent number: 11078744
    Abstract: In wellbore completions it is sometimes desirable to seal the wellbore against fluid flow or to anchor a component within the wellbore. However, running such a plug into the wellbore has been problematic on occasion such as when the nose of the plug encounters an object within the wellbore such as a sand bridge or other obstruction. In those instances, the way of the tubular pushing the plug into the wellbore combined with the nose of the plug being unable to pass the instruction causes the plug to prematurely set. Such an instance the plug may need to be drilled out in order to proceed. In the present embodiment the tubular used to move the plug into the well is attached to the nose of the plug so that the force provided to the plug by the tubular is transmitted only to the nose of the plug preventing the plug from presetting and allowing the plug to push past or through an obstacle within the wellbore.

  • Patent number: 8939205
    Abstract: The methods described are for determining distribution, orientation and dimensions of networks of hydraulically-induced fractures within a subterranean formation containing fluids. Micro-seismic events are generated, after cessation of fracturing and establishment of fracture networks, by particles introduced into the fractures which are capable of explosive or chemical reaction. In one method, attachment site particles are positioned within the formation during fracturing and additional reactive particles are later introduced. The reactive particles attach to the attachment sites and, upon a triggering event, react to produce micro-seismic events. The waves generated by the micro-seismic events are used to provide mapping of the effective fracture space. Additionally, time-lapse mapping is provided with use of “species” of attachment sites and reactive particles.

  • Publication number: 20140345847
    Abstract: The power charge of a wireline pressure setting assembly includes a barrier located adjacent an open upper end of the power charge. The barrier centralizes the power charge in horizontal applications to ensure the associated tool properly sets. The barrier also limits how much of the power charge can flow out of its housing in a horizontal application. The barrier can be porous or impervious to contain as much of the power charge in a small sub-chamber in the pressure chamber defined by the barrier. Once ignition starts in the power charge the barrier can be consumed or otherwise disabled for the normal functioning of the setting device to set a tool and release from the set tool in a normal manner.
