Abstract:

A wellbore servicing apparatus comprising an inflow control assembly having an inflow flowbore and a stimulation assembly having a stimulation flowbore is disclosed. A method of servicing a wellbore comprising placing a stimulation assembly in the wellbore and placing at least one inflow control assembly in the wellbore, the at least one inflow control assembly comprising a selectively adjustable inflow sleeve, is also disclosed. A method of servicing a wellbore comprising opening a plurality of jetting nozzles in a production string located in a wellbore adjacent a formation, jetting a treatment fluid through the nozzles and perforating and/or fracturing the formation, at least partially closing the plurality of jetting nozzles, opening a plurality of inflow ports to allow fluid to flow from the formation into the production string, and filtering the fluid prior to the fluid entering the inflow ports is disclosed.

Abstract:

A flow control apparatus () for controlling the inflow of production fluids into an interior passage () of a tubular member () in a wellbore includes a flow restrictor () positioned in the flow path between an exterior of the tubular member () and the passage (). The flow restrictor () has an active chamber () and a bypass chamber (). A bypass tubing is disposed within the bypass chamber (). The bypass tubing () has a constant effective flow area for allowing production fluids to enter the passage () from the bypass chamber (). A plurality of flow blocking members () is disposed within the active chamber () and cooperate with outlets () of the tubular member () to autonomously vary an effective flow area for allowing production fluids to enter the passage () from the active chamber based upon the constituent composition of the production fluids.
