摘要： A screen section is made with variable resistance to flow in the screen material to balance the flow along the screen length. In one variation different discrete zones have screens configured for different percentages of open area while all have the same particle filtration capability. In another variation discrete portions have differing amounts of overlapping screen portions so as to balance flow without affecting the particle size screened. The cross-sectional shape of a wire wrap underlayment for the screen is made closer to trapezoidal to decrease the angle of opening for the incoming flow paths toward the base pipe. In this manner flow resistance is reduced and flow is increased due to reduced turbulence.

摘要： A liner rotates a bit to make more hole. The liner has openings with inserts in them to lend torque resistance to the liner. The inserts have a passage with a send control media in the passage and a seal so that the liner can hold pressure for run in to get proper circulation through the bit. When sufficient hole is made, the liner is hung off an existing cemented tubular and the seal for the passages with the sand control media is removed by a variety of techniques so that the formation can be produced in a single trip.

摘要： Systems and methods for increasing fluid flow characteristics within a hydrocarbon production tubing string within a wellbore. An expansion member is passed through the interior flowbore of one or more production tubing string members. The expansion member smoothes the interior surface of the flowbore and may radially expand the interior surface of the flowbore.

摘要： One or more valves can be run into a string to land near associated ports in the string for injection or/and production service. When multiple valves are installed they can be initially configured to balance flow into or from a zone. The position of each valve can be altered without removal from the string preferably by a wireline shifting tool. One or more valves can also be removed and replaced when worn preferably using a wireline run tool. The valves can come with an integral sand control feature to facilitate production. Sensors to monitor well conditions and to transmit data to the surface can also be incorporated into the valve module.

摘要： The apparatus allows mixing of a solid and a fluid continuously to facilitate downhole operations, especially gravel packing. The apparatus comprises a solids hopper, with preferably an internal auger, to meter the solids flowrate. The solids drop into a second feeder which empties into a mixing chamber. Liquid can be directed into an annular space formed in the mixing chamber around the periphery of the second auger, or could be piped into the second auger itself. A triplex pump is connected to the mixing chamber and draws the mixed solid and fluid and pumps it to sufficient pressures for use in a wellbore.
