摘要： A method for completing a well in a single trip, including: inserting a completion tool assembly into the well, the completion tool assembly having a gravel packing assembly and a service tool assembly slidably positioned substantially within an interior cavity in the gravel packing assembly; removably coupling the service tool assembly and the gravel packing assembly; plugging at a first location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the first location through a first fluid flow path to an exterior of the completion tool assembly; circulating a gravel pack slurry through the completion tool assembly; plugging at a second location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the second location through a second flow path that reenters the interior channel at a location distal of the first and second plugging locations; and circulating a filter cake stimulating fluid through the well completion assembly.

摘要： A method for completing a well in a single trip is described, which includes inserting a completion tool assembly into the wellbore. The completion tool assembly includes a gravel packing assembly having a central channel substantially therethrough and a service tool assembly slidably positioned within the central channel. The service tool includes a pressure pulsating rotating jetting tool, connectable to a washpipe via a differential valve. By selectively dropping a plurality of plugging devices into the completion tool, multiple operations may be selectively performed in the wellbore in a single trip. In this way, the gravel packing and stimulating operations may be performed by a single completion tool assembly in a single trip into the wellbore, thus reducing the cost and time for performing the gravel packing and stimulating operations.

摘要： The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.

摘要： An interventionless actuator for oil well tools is described wherein the actuator comprises at least one floating piston adapted to equalize a pressure differential and lock onto an actuating member. An interventionless actuator is described that is charged to an initial energy level less than the expected at-depth well pressure and then recharged down hole to approximately the at-depth well pressure by a floating piston. At the time of desired interventionless actuation, the actuator is overcharged to a pressure greater than the at-depth well pressure, which pressure is reacted by an actuating piston to generate an actuating movement.
