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.

Abstract: A mechanism for pressurized delivery of material into a well without exposure to a high pressure pump. The mechanism may include material delivery equipment that is coupled to the high pressure pump or other pressure inducing equipment through a material carrier that intersects a fluid line from the pump. The material carrier may include chambers that are reciprocated or rotated between positions that are isolated from the fluid line and in communication with the fluid line. While isolated from the fluid line, the chambers may be filled with oilfield material which may then be delivered to the fluid line when positioned in communication therewith. In this manner, a supply of the oilfield material may be retained in a substantially isolated state relative to the pump and components thereof which may be susceptible to damage from exposure to the oilfield material.

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.

Abstract: An assembly and techniques for employing multiple motors to drive an oilfield injector. The injector is configured to drive a well access line such as coiled tubing and the motors may be electric in nature. Additionally, the motors are configured to operate at substantially sufficient cooling speeds for electric motors. Nevertheless, the motors are coupled through a common differential mechanism such that a range of differential speeds may be derived via comparison of the operating speeds of the motors. Thus, a wide array of injection speeds may be employed without requiring the motors to operate at dangerously low speeds in terms of electric motor cooling.
