摘要： Systems and methods of the present disclosure relate to shifting mandrels in downhole tools based on hydraulic pressure. A downhole tool includes an outer sleeve, an inner mandrel and a valve plate coupled to the inner mandrel. The valve plate and the inner mandrel are configured to shift axially within the outer sleeve. The valve plate is further configured to pass a portion of fluid through the valve plate and pass another portion of the fluid around the valve plate, based on a tensile force or a compressive force exerted on the downhole tool.

A hydraulic set packer assembly including a flow control nipple, a hydraulic set packer connected to the nipple, and an intensifier disposed in the packer assembly. A method for setting a hydraulic set packer in a borehole including applying pressure to an intensifier, and changing a pressure at an outlet port disposed in fluid communication with the intensifier chamber relative to an input pressure applied to the intensifier.

摘要： Valve assemblies are disclosed for use in the oil and gas industry. A disclosed valve assembly includes a housing having a bore; a valve member arranged within the housing which is movable relative to the bore between open and closed positions. The valve member includes a cutting feature and a sealing surface; a cutting component that cooperates with the cutting feature when the valve member is in moved to the closed position; a first seal element arranged within the housing and providing a first seal relative to the sealing surface; and a second seal element arranged within the housing and providing a second seal relative to the sealing surface. The second seal element is movable relative to the housing bore between first and second positions. A corresponding method of controlling communication along a bore of a housing is also disclosed.

摘要： Pressure-activated valve assemblies and methods to remotely activate a valve are disclosed. A pressure-activated valve assembly includes a valve, a latch mechanism configured to shift the valve to an open position, and a pressure-activated indexing mechanism that is initially engaged to the latch mechanism. The pressure-activated indexing mechanism is initially in an unarmed mode. After the pressure-activated indexing mechanism is in an armed mode, applying at least one cycle of threshold pressure to the pressure-activated indexing mechanism disengages the latch mechanism to shift the valve to the open position. The pressure-activated valve assembly also includes a remote-activated downhole system configured to receive an activation pressure signal having a signature profile, and in response to receiving the activation pressure signal, arm the pressure-activated indexing mechanism.

摘要： A combination of an autofill tube and an interchangeable ball cage for use in an autofill conversion assembly during well operations includes the tube extending to a downhole opening, the tube has a mounting mechanism to releasably mount the tube within an outer member; the interchangeable ball cage having a main body forming a bore; a downhole opening; circulation ports; and an attachment mechanism removably connecting the main body to the autofill tube; the downhole opening has a diameter selected to prevent a conversion ball from falling therethrough; the circulation ports provide fluid flow through the interchangeable ball cage such that the circulation ports have a number and size to create a preset maximum flowrate associated with the combination of the autofill tube and the interchangeable ball cage; and the interchangeable ball cage is to be selected based on the preset maximum flowrate desired at a well site.

摘要： A system and method for injecting bailer content utilizing a dump bailer having an elongated, flexible bailer receptacle secured between a head assembly and an injection assembly. Disposed within the dump bailer are first and second piston assemblies, each of which includes a piston having a central fluid passage with a pressure actuated flow control mechanism in the form of a rupture disk disposed along the fluid passage of the piston. An electric, positive displacement pump within the head assembly draws wellbore fluid into the dump bailer assembly to drive the first piston assembly towards the second piston assembly so as to release bailer content into a wellbore. The elongated flexible bailer receptacle may be a hose stored on a bailer receptacle reel, which hose may be paid out by the reel to a length that corresponds with a volume of bailer content to be released into the wellbore.

摘要： A system for well control during tripping phases in drilling operations in a wellbore, the system comprising: a drill string extending from an entry of the wellbore to a drill bit at a distal end of the drill string within the wellbore; a near bit sub mounted along the drill string adjacent to the drill bit; a first smart multi-directional two-way check valve mounted along the drill string adjacent to the near bit sub; and a controller configured to operate the valve. The controller controls the valve to apply suction or discharge flow to the near bit sub to counter inertial effects of drilling mud viscosity within the wellbore.
