20110308806 | METHOD AND APPARATUS FOR AUTONOMOUS DOWNHOLE FLUID SELECTION WITH PATHWAY DEPENDENT RESISTANCE SYSTEM - 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.

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. | 12-22-2011 |

20130075107 | METHOD AND APPARATUS FOR AUTONOMOUS DOWNHOLE FLUID SELECTION WITH PATHWAY DEPENDENT RESISTANCE SYSTEM - An apparatus is described for controlling flow of fluid in a subterranean formation based on a selected characteristic of fluid flow, such as viscosity, velocity or density, as that characteristic varies over time. A pathway-dependent resistance assembly, such as a vortex chamber having two inlets and an outlet, provides varying resistance to fluid flow based on the ratio of flow from the inlets, the direction of flow as directed by the inlets, and the characteristic of the fluid. The incoming flow ratio is preferably determined by flowing fluid through a plurality of passageways having differing flow rate responses to fluid having differing characteristics. Fluid of a selected characteristic will encounter lesser resistance to flow across the system, while fluid of an un-favored characteristic will encounter greater resistance to flow. Thus, flow of well fluids can be autonomously restricted as the fluid characteristics change over time. | 03-28-2013 |

20140251627 | Mechanically Adjustable Flow Control Assembly - A flow control assembly can be mechanically adjusted, rotationally or translationally, inside a tubing downhole between multiple positions by an intervening tool from the surface to change resistivity to flow through the flow control assembly. The positions among which the flow control assembly can be adjusted can include a closed position, a fully open position, and positions at which fluid experiences various resistances prior to flowing to an inner area of the tubing. | 09-11-2014 |
20150226041 | SUBTERRANEAN WELL TOOLS WITH DIRECTIONALLY CONTROLLING FLOW LAYER - Disclosed herein is a flow direction controlling layer for use in controlling the flow of fluids in subterranean well tools. The control layer comprises micro check valve arrays formed in the tool. | 08-13-2015 |
20150330191 | Well Flow Control with Acid Actuator - A well production device includes a production tubing with a fluid passage between the exterior of the tubing and a center bore of the tubing. A fluid barrier is provided sealing the fluid passage. The device has a chamber comprising a dissolving fluid adapted to dissolve the fluid barrier when in contact with the fluid barrier and an actuator configured to release the dissolving fluid into contact with the fluid barrier in response to a signal. | 11-19-2015 |
20150337622 | DISTRIBUTED INFLOW CONTROL DEVICE - Certain aspects of the present invention are directed to a distributed inflow control device that can be disposed in a wellbore through a fluid-producing formation. The distributed inflow control includes a shroud that can be disposed in the fluid-producing formation. The shroud circumferentially covers a section of a tubing string. The shroud includes a profile having multiple flow paths between the fluid-producing formation and an inner volume of the section of the tubing string. Each flow path restricts a fluid flow through the flow path and is independent of each other flow path. The distributed inflow control device also includes a seal over the profile including the flow paths. The seal causes fluid to flow from an inlet to an outlet of each flow path and prevents fluid from entering or exiting each flow path at a point other than the respective inlet or the respective outlet. | 11-26-2015 |
20160024882 | Liquid Valve for Flow Control Devices - Certain aspects of the present invention are directed to a liquid valve assembly that can be disposed in a wellbore through a fluid-producing formation. The liquid valve assembly can include a housing and a liquid valve. The housing can define an inner chamber and an opening adapted to allow fluid to flow between the inner chamber and a passageway. The liquid valve can be disposed in the inner chamber. The liquid valve can include a yield stress fluid. The yield stress fluid can prevent fluid from flowing between the inner chamber and the passageway. | 01-28-2016 |
20160024883 | Liquid Valve for Flow Control Devices - Certain aspects of the present invention are directed to a liquid valve assembly that can be disposed in a wellbore through a fluid-producing formation. The liquid valve assembly can include a housing and a liquid valve. The housing can define an inner chamber and an opening adapted to allow fluid to flow between the inner chamber and a passageway. The liquid valve can be disposed in the inner chamber. The liquid valve can include a yield stress fluid. The yield stress fluid can prevent fluid from flowing between the inner chamber and the passageway. | 01-28-2016 |
20160024897 | Well Screen Assembly with Extending Screen - A well screen assembly residing in a well bore has a base pipe and a filtration screen carried on the base pipe. The screen is radially extended with force from fluid while maintaining the base pipe radially unextended. | 01-28-2016 |
