  • Publication number: 20190017333
    Abstract: A valve assembly for reversibly governing fluid flow through coiled tubing equipment. Valves of the assembly may be directed by a telemetric line running from an oilfield surface. In this manner, valve adjustment and/or reversibility need not require removal of the assembly from the well in order to attain manual accessibility. Similarly, operation of the valves is not reliant on any particular flow rate or other application limiting means. As such, multiple fluid treatments at a variety of different downhole locations may take place with a reduced number of trips into the well and without compromise to flow rate parameters of the treatments.

  • Patent number: 10047592
    Abstract: A technique facilitates performance of a perforating operation in a wellbore. The technique comprises positioning a perforating gun assembly downhole in a wellbore via coiled tubing. The perforating gun assembly has a plurality of individually controllable perforating gun sections which may be selectively fired at different well zones. An optical fiber is deployed along the coiled tubing to deliver control signals to the perforating gun assembly. The control signals enable sequential firing of the individually controllable perforating gun sections at the desired locations, e.g. well zones, along the wellbore.

  • Patent number: 9863228
    Abstract: A system includes a regional blending facility having a number of bulk receiving facilities, where each bulk facility receives and stores a particle type having a distinct size modality, a bulk moving device that transfers particles between the bulk receiving facilities and of a blending/continuously receiving vessel and/or a mixer, and a carrying medium vessel. The mixer receives particles from the blending/continuously receiving vessel and/or the bulk moving device, receives a carrying medium from the carrying medium vessel, mixes the particles with the carrying medium, and provides a mixed treatment fluid. The system includes a fluid conduit that fluidly couples a wellsite location with the regional blending facility, where the fluid conduit delivers the mixed treatment fluid to the wellsite and/or delivers produced fluid from a wellbore positioned at the wellsite to the regional blending facility.

  • Publication number: 20170097000
    Abstract: A pump has power and fluid ends wherein one or more of the drive rods are offset from the plungers. An offset coupler connects a drive rod to an offset plunger. A method includes connecting the offset power end to the standard fluid end using the offset coupler. A repair and maintenance system includes inventories of standard fluid ends, power ends including offset power ends, and adapters, and a population of in service pumps, whereby the pumps can be repaired by removing and replacing the power ends from inventory using the adaptor where the replacement power end unit is offset. Another method includes removing and replacing the power end with one from the inventory, wherein the adapter is used in the case of an offset power end, whereby the offset and standard power ends may be used interchangeably.

  • Patent number: 9222334
    Abstract: A technique facilitates the delivery and testing of a tool string assembly downhole. The technique employs at least one rotatable element valve in the tool string at a location which enables the rotatable element valve to be used for selectively blocking or allowing fluid flow along an interior passage of the tool string. A one-way valve, such as a flapper valve, dart valve, or spring loaded ball valve, is deployed within a rotatable element of each rotatable element valve to combine flow control functions, thus enabling a shorter tool string section. The at least one rotatable element valve also may be designed to facilitate pressure testing of the tool string.
