    Abstract: A tunable pneumatic fracturing system and process useable in some instances to extract oil and gas. Some embodiments provide a pneumatic fracturing tool with an elongated body that (a) contains (i) a propellant supply source intermediate opposed propellant gas discharge assemblies, (ii) a control system, and (iii) a communications port, and (b) has roller assemblies at opposed ends of the body. The tool can be tuned to provide gas pulse amplitudes and frequencies that react with the resonant frequency or other aspect of an adjacent earth formation. Some tool embodiments can variably sweep a rock formation and adjust the pressure pulse amplitude and frequency to disrupt the formation in a more productive manner. Some tools can penetrate vertical bore wells as well non-vertical bore wells. In some systems, the tool is transported and operated by a control truck and can be commanded to download operational data during or after use.

  • Patent number: 8997855
    Abstract: An apparatus includes a body shaped to deform a wellbore tool in a predetermined manner. A vibration device applies a vibration to the body to reduce a frictional force caused when the body deforms the wellbore tool. In one arrangement, the vibration devices imparts a resonant wave motion to a swaging apparatus that is being pushed through a passage of a wellbore tubular. A swaging body vibrates at a resonant frequency along the long axis of the wellbore tubular and/or normal to long axis of the wellbore tubular. The relative motion between the swaging body and the tubular member reduces the force required to expand the wellbore tubular. Optionally, a controller operatively connected to the vibration device adjusts the operation of the vibration device in response to the sensor measurements of the vibrations in the swage body.

    Abstract: Present embodiments are directed to coupling a cementation assembly with a hung or set liner string in a well and moving the liner string during a cementation operation. Specifically, for example, a process in accordance with present techniques includes running a cementation assembly into a well on drill pipe and engaging, with a distal end of the cementation assembly, a liner top assembly of a liner string that is positioned downhole in the well, wherein the liner string was previously positioned downhole in the well without being cemented into the well. Further, the process includes latching the cementation assembly with the liner string such that movement of the cementation assembly is translated to the liner string, and flowing cement through the drill pipe and into the liner string while moving the cementation assembly and the liner string.

    Abstract: Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear.

    Abstract: This stuffing box (46) defines a circulation passage (66) of a cable working line (28), a packer (70), and a back-pressure resistant valve (74). The passage (66) extends between an upstream end (62) of the stuffing box (46), intended to be connected to a well, and a downstream end (64). The back-pressure resistant valve (74) is arranged in the passage (66) to prevent, in case of break of the line (28), the back-pressure of a fluid from the upstream end (62) towards the downstream end (64). The or each packer (70) is situated between the upstream end (62) of the stuffing box (46) and the back-pressure resistant valve (74). No packer (70) is arranged between the back-pressure resistant valve (74) and the downstream end (64).

  • Publication number: 20130043031
    Abstract: A set of manifold string members usable to selectively control separate flowing fluid streams of varying velocities for operations of well construction, injection or production of fluid mixtures of liquids, gases and/or solids, that can be injected into, or taken from, one or more proximal regions of a subterranean passageway, underground cavern, hydrocarbon or geothermal reservoir. Fluid communicated through a manifold string radial passageway of a manifold crossover, between conduit strings and at least one other conduit, can be controlled with at least one flow controlling member, communicating with a passageway member from an innermost, concentric, and/or annular passageway. Fluid communication can be selectively controlled for various configurations of one or more substantially hydrocarbon and/or substantially water wells, below a single main bore and wellhead.

  • Patent number: 8317012
    Abstract: The invention disclosed provides a drive head assembly for a fluid conveyor system that propels a fluid entraining conveyor through a well bore to carry fluids to the surface. The invention is comprised of a pair of synchronized follower wheels connected to a set of counter rotating sheaves. A fluid entraining conveyor is wrapped in a “figure-8” conveyor path around the sheaves in a plurality of coaxial grooves and around a distal sheave located in the fluid in the well bore. The coaxial grooves incorporate a unique shape which in conjunction with the wrap pattern provide improved tractive qualities and thus reduce tension in the conveyor and increase the durability of the conveyor. The conveyor can run at increased speeds and with no tension on the downward portion of the conveyor resulting in higher efficiency and less down time due to breakage.

  • Patent number: 8205674
    Abstract: An apparatus, system, and method are disclosed for in-situ extraction of hydrocarbons from a hydrocarbon-bearing formation. The system includes a well drilled through a hydrocarbon-bearing formation, and a completion unit that places an injection tube near a fluid injection point near the bottom of a target zone and a production tube near a fluid production point near the top of the target zone. An isolation unit isolates the fluid injection point from the fluid production point such that injected fluid flows through the target zone. The system further includes a heat source, and a fluid that delivers thermal energy from the heat source to the hydrocarbons in the target zone to entrain the hydrocarbons in the fluid. The resulting production fluid is heated, free hydrogen is added, and the production fluid is treated on a catalytic reactor to reduce the size of the hydrocarbon chains.

  • Publication number: 20120048543
    Abstract: A method for pumping fluid at a wellhead is provided. The invented method will improve liquid removal by eliminating the need to transport liquid produced from a well to containment facilities using trucks or large diameter pipelines capable of accommodating periodic surges of a high volume of fluid. The danger that the liquid will freeze in cold weather is also addressed. The invention removes liquid from the well site through a small diameter pipeline as a continuous flow at a constant flow rate. An apparatus for removing liquid from the well site is also provided.

  • Patent number: 8087904
    Abstract: A hybrid hydraulic-electric pumping unit (12) with downstroke energy recovery is disclosed which is operated in a conventional flow mode to supply hydraulic fluid to a hydraulic ram (26), and then is operated in a reverse flow mode to receive the hydraulic fluid from the hydraulic ram (26) and turn an electric motor (16) to generate electric power. A single hydraulic hose (48) connects the pump (18) to the hydraulic ram (26), and is used for both passing the hydraulic fluid from the pump (18) to the hydraulic ram (26) and from the ram (26) to the pump (18). The potential energy of the weight of sucker rods (10) lifted in operating the pumping unit (12) is recovered by operating the pump (18) and motor (16) with return of the hydraulic fluid from the hydraulic ram (26) through the pump (18), which turns the motor (16) to generate electric power.
