With Means For Injecting Solid Or Particulate Material Into The Well Patents (Class 166/75.15)
  • Patent number: 9739111
    Abstract: A controlled aperture ball drop includes a ball cartridge that is mounted to a frac head or a high pressure fluid conduit. The ball cartridge houses a ball rail having a bottom end that forms an aperture with an inner periphery of the ball cartridge through which frac balls of a frac ball stack supported by the ball rail are sequentially dropped from the frac ball stack as a size of the aperture is increased by an aperture controller operatively connected to the ball rail. A control console displays a user interface that permits an operator to control the controlled aperture ball drop to drop frac balls only when desired.

  • Publication number: 20150114626
    Abstract: An object launching apparatus for a well has a housing, a flow mandrel, and a cage. The flow mandrel is disposed in the housing's internal chamber, and a flow passage in the mandrel communicates flow from the housing's inlet to the mandrel's flow port, which in turn communicates with the housing's outlet. The cage is disposed in the internal chamber and defines pockets for holding the objects. A motor and shaft move the cage in the housing relative to the mandrel's flow port so the cage's pockets can be selectively positioned in communication between the mandrel's flow port and the housing's outlet. This allows any of the object(s) held in the positioned pocket to be launched into the flow to the well. Preferably, the motor rotates the shaft so the cage can ride linearly along the shaft's thread and the cage can rotate through a cammed engagement with the housing.

  • Publication number: 20150090438
    Abstract: A ball dropper has a stack of trays that have solid portions for supporting a ball and open portions to allow a ball to pass through a tray. Fixed barriers limit the travel of the ball with the rotating tray to allow the ball to become unsupported so that it can be caught on the tray below. A stepper motor precisely makes the required incremental rotation to allow the addition of the next ball at the top. Once the trays are filled or the balls loaded are advanced such that the lead ball is on the last tray any further rotation will start to discharge the balls with each increment of rotation. The device is easy and cheap to fabricate and presents a reliable way to get jam free operation while having a housing that will tolerate the operating pressures in the wellbore.

The activation devices are launched into the principal process-fluid stream inside the cementing head, and may be darts, balls, bombs, canisters and combinations thereof. The launching chambers are in fluid communication with an external power source for launching the activation device into the principal process-fluid stream.

  • Patent number: 8584749
    Abstract: Methods for hydrocarbon recovery from a subsurface formation include removing a mixture comprising hydrocarbons and particulate solids from a first formation. At least a portion of the hydrocarbons are separated from the particulate solids. The particulate solids are separated into a plurality of streams. A mixed slurry comprising a first portion of the plurality of streams is injected through a first pipe into the first formation. A waste stream comprising a second portion of the plurality of streams is injected through a second pipe into a second formation. The first formation and the second formation lie in a substantially vertical line.

  • Patent number: 8573301
    Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation.

  • Patent number: 8567488
    Abstract: The present invention relates in general to equipment for servicing subterranean wells and in particular to a cementing head that is intended to drop a combination of darts, balls, bombs and canisters in order to activate downhole equipment, launch cementing plugs, deliver chemical products, or the like. A cementing head comprises a modular valve apparatus, comprising at least two detatchable parts. This arrangement allows the operator to remove and disassemble the valve apparatus at the wellsite. Thus, repairs and maintenance may be performed at the wellsite and the valve apparatus may be reassembled and reinstalled, obviating the need to transport the equipment to a central facility.

  • Patent number: 8561684
    Abstract: An apparatus for holding and launching down-hole actuation devices that has a body, a bottom end, a top end and a long bore between the ends. Moveable and protruding into the long bore are retainers upon which down-hole actuation devices may rest. Retainers are moved by a lockable hydraulic drive system. Additionally, a method for loading the apparatus with down-hole actuation devices and for launching said devices into a well bore is provided.

  • Patent number: 8522896
    Abstract: Processes and apparatus that continuously change the physical state and characteristics of drilling fluids at planned periodic intervals to consistently and correctly compensate for differing geological formation properties, wellbore characteristics, rate of penetration, solids removal efficiency, and other essential factors involved in the drilling process, comprising: initiating a system correction of a Minimum Base Required (“MBR”); and administering a dilutant to a drilling fluid according to the MBR. The system corrections may be performed recursively, adjusting the system's base dilutant and chemical product additions according to MBR. The drilling fluid consistency produced is based upon several drilling-rig specific parameters.

  • Patent number: 8496062
    Abstract: The disclosure provides a goat head, as a mixing block, for multiple fluids in oilfield applications, the goat head having a reversing directional flow, mixing portion, wear reduction surfaces, and restricted outlet bore. The goat head provides an underneath approach for piping, reducing the overall height, and mixes the fluids dynamically within the goat head from angled flow paths. The goat head then reverses at least a component of the fluid flow direction that enters the wellbore below the goat head and exits the goat head into the well therebelow. The goat head to contains hardened wear surfaces, including surfaces in specific zones, to resist erosion caused by the reversing directional flow. A restricted outlet bore has a cross-sectional area that is less than the sum of cross-sectional areas of the inlets to assist in creating higher velocity and streamlined flow as the fluid exits the goat head.

  • Patent number: 8490685
    Abstract: A method and apparatus associated with the production of hydrocarbons. In one embodiment, the method describes connecting multiple wells to a stimulation fluid pumping system via a pumping system manifold. The pumping system manifold is adjusted to provide a first well flow path from the stimulation fluid pumping system to a first well. Then, a first stimulation treatment is pumped into the first well. Concurrently with the pumping of the first stimulation treatment, a second well is prepared for a second stimulation treatment.
