摘要： Disclosed is a new and novel poppet type safety valve useful in flow conduits in fluid storage well systems. The safety valve is programmable to automatically close at various predetermined ratios of production mass flow rate-ambient pressure to prevent undesirable high flow rates or uncontrolled out-flow of fluid stored in a reservoir if the flow conduit or wellhead is damaged. This safety valve is lowered into and locked and sealed in a landing nipple in the well conduit. The safety valve has a variable bias which biases the valve member toward open position and a variable flow restrictor which is automatically actuated by a sensing actuator continually sensing reservoir pressure to vary the restricted annular flow area between the valve housing and inside of the well conduit for closure at the desired flow rate. The valve element has a through flow passage with locking recesses in the flow passage into which the sensing actuator may be releasably locked. The sensing actuator responds to changes in stored gas density and ambient pressure and automatically varies the restricted flow area accordingly. The safety valve may be operated to disconnect the valve housing, with or without the sensing actuator, for expending downwardly in the well conduit.

摘要： A system and method for servicing subsea wells with a flexible riser. The flexible riser can be modified for use either with wireline or through the flow line tools. The flexible riser eliminates the requirement for motion or heave compensating equipment associated with rigid marine riser systems. The flexible riser, lower riser package and associated surface support equipment can be used to obtain vertical access to a subsea well without the need to use a drill ship or semisubmersible.

摘要： A hydraulically set retrievable well packer, with dual mandrels connectable into well tubing, for sealing the tubing to and anchoring the packer body in well casing utilizing a unique c-ring slip system. The mandrels are slidably connected for limited longitudinal movement in the packer body, which eliminates tubing spacing-out and temperature length change problems. There is a separate mandrel through the packer body for conducting flow from the casing annulus below the set packer. An internal lock system is provided to retain the packer in set position. If tubing parts above the set packer, the mandrels are supported and metal-to-metal sealed in the packer preventing tubing below the packer from falling. The packer may be retrieved by cutting one or both mandrels above the packing elements and picking up to release an internal connector which allows the slips and packing element to retract and the packer to be retrieved from the well. The anchoring, sealing and releasing means of this invention can be readily adapted for use on a single or multiple mandrel well packer.

摘要： Remote operation of downhole tools in a subterranean wellbore is performed by inserting untethered, mobile devices sequentially into the wellbore. The mobile devices can include motive means, power supply, communication and data storage means, etc. In one embodiment, the method comprises maneuvering a first mobile device into proximity with a downhole tool, the device powering the tool. The first device is then removed, such as by flowing up or dissolving. The now-powered tool is used to perform a test or other operation. A second mobile device is maneuvered into proximity with the downhole tool and data is transferred. The second device is retrieved with the data or, using on-board logic devices, provides “if-then” commands to the downhole tool. Alternately, a third mobile device can be used to power and transfer commands to the tool. The method can be used for various tasks, such as opening bypass ports on ICD valves.

摘要： Apparatus and methods for controlling the flow of fluid, such as formation fluid, through an oilfield tubular positioned in a wellbore extending through a subterranean formation. Fluid flow is autonomously controlled in response to change in a fluid flow characteristic, such as density or viscosity. In one embodiment, a fluid diverter is movable between an open and closed position in response to fluid density change and operable to restrict fluid flow through a valve assembly inlet. The diverter can be pivotable, rotatable or otherwise movable in response to the fluid density change. In one embodiment, the diverter is operable to control a fluid flow ratio through two valve inlets. The fluid flow ratio is used to operate a valve member to restrict fluid flow through the valve.

摘要： An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.
