Abstract: An apparatus for controlling the flow of reservoir fluids into production tubing comprises a base pipe, a screen, a nozzle being adapted to receive filtered reservoir fluids passing through the screen, and a diverter adapted to receive the fluids from the nozzle and to divert such fluids into a port extending into the base pipe. The nozzle includes at least one converging-diverging section, whereby pressure of the fluids passing there-through is reduced.

Abstract: A method and system (26) for remediating a lost circulation zone (54) in a wellbore (12). A flexible liner (18) is deployed adjacent the lost circulation zone (54) that blocks fluid communication between the wellbore (12) and surrounding formation (13). The liner (18) material has a designated yield and tensile strength, so that in response to pressure applied in the wellbore (12) the liner (18) flexes and conforms to contours in the wellbore (12). The liner (18) remains intact during deformation to maintain the flow barrier between the wellbore (12) and formation (13). The liner (18) is set in the wellbore (12) with a bottom hole assembly (44) that includes an outer housing (10) for protecting the liner (18) during the trip downhole. Drill pipe (42) can be used for deploying the bottom hole assembly (44), and for conveying pressurized fluid for setting the liner (18). An expander (30) is included with the bottom hole assembly (44) for mechanically conforming the liner (18) to the wellbore sidewalls.

Abstract: A method is provided for gravel packing an open hole section of a hydrocarbon producing well (10). The method includes injecting a slurry comprising particulates dispersed in a carrier fluid into an annular space (60) in the open hole section of the wellbore, and depositing the particulates in the annular space to form a gravel pack (70). Typically, inter-granular bonds form among the particulates, and thus form the gravel pack. In some embodiments, the inter-granular bonds generate grain-to-grain compressive strength which is strong enough to keep the gravel pack immobile.

Abstract: A method includes drawing a fluid into a flow control assembly coupled to a completion string positioned within a wellbore, the flow control assembly including a first fluidic device and a second fluidic device, where the first and second fluidic devices exhibit different flow characteristics. A flow condition of the fluid circulating through the first and second fluidic devices is measured with a plurality of fluid sensors, and a water cut of the fluid is estimated based on the flow condition measured by the plurality of fluid sensors.

Abstract: A technique facilitates assembly and deployment of a sand screen assembly string. The sand screen assembly string is constructed by providing sequential base pipe joints combined with corresponding alternate path tubes. The sequential base pipe joints are joined together in a manner which brings sequential, corresponding alternate path tubes into close proximity with each other at a location external to the sequential base pipe joints. The sequential, corresponding alternate path tubes are readily coupled together by a connector which is movably mounted along at least one of the alternate path tubes for movement into engagement with the other alternate path tube.
