A flow control valve sub including a tubular valve sub housing having a sub central passage and a valve cavity formed in a sidewall of the sub housing. At least one piston aperture and at least one constant area pilot aperture communicate between the valve cavity and the sub central passage, while a piston is positioned in the piston aperture with the piston moving to at least partially cover and uncover the flow port in order to create a variable flow path between the valve cavity and the sub central passage. A beam spring is supported at a location within the cavity on each side of the piston and biases the piston toward a less flow restrictive position relative to the flow port and a valve cover is positioned to substantially close the valve cavity.

Autonomous flow controller device

A screen system formed of a first screen sub and a second screen sub joined by a connector sub. The connector sub includes (i) a pipe coupling assembly connecting the base pipes of the first and second screen subs; (ii) a substantially impermeable shroud formed around the pipe coupling assembly and creating a connector annulus between the shroud and pipe coupling assembly; and (iii) end rings including a substantially annular flow passage connecting the first and second screen annuluses to the connector annulus.

Over-coupling screen communication system

A screen system having a first screen sub including a first base pipe wrapped with a first screen section; a second screen sub including a second base pipe wrapped with a second screen section; and a pipe coupling assembly joining the first and second base pipes. A section of filter material extends between the first and second screen sections, and extends over the pipe coupling assembly, thereby forming an annular flow path from the first screen section to the second screen section over the pipe coupling assembly.

A method of treating a subterranean formation. The method may include providing a well treatment including a treatment complex formed of a treatment agent encapsulated, entrapped, or embedded in a polysaccharide, introducing the treatment complex into a wellbore through a subterranean formation, and allowing the treatment complex to release the treatment agent over a release time period. The method may include allowing the treatment complex to release the treatment agent after a delay time period from the introduction of the treatment complex into the wellbore.

Polysaccharide delivery unit for wellbore treatment agent and method

An apparatus for controlling a flow of a fluid between a wellbore tubular having an opening and a formation includes a particulate control device and a flow control device positioned adjacent to the particulate control device. A flow path is formed between the opening of the wellbore tubular and the formation and that is internal to the particulate control device and the flow control device. The apparatus may include an additive supply line having an outlet positioned to dispense at least one additive into the flow path. A related method for controlling a flow of a fluid between a wellbore tubular having an opening and a formation may include positioning a flow control device adjacent to a particulate control device in the wellbore and dispensing at least one additive into a flow path internal to the particulate control device and the flow control device.

System and method for treatment of well completion equipment

An apparatus and associated method for controlling a flow of a fluid between a wellbore tubular and a formation may utilize a particulate control device positioned external to the wellbore tubular and a flow control device having a retrievable flow restriction element that controls a flow parameter of a fluid flowing between the particulate control device and a bore of the wellbore tubular. The flow control device may be re-configured in the wellbore and/or be used to inject a fluid into the formation.

Flow control device with one or more retrievable elements and related methods

A method of providing a flow control device is disclosed, which one aspect may include: defining a flow rate; defining a desired relationship between a parameter of the flow control device that exhibits a substantial change when a selected property of the fluid changes in a first range and remains substantially constant when the selected property is in the second range; determining using a computer and a simulation program the relationship between the performance parameter and the selected property over the first range and the second range for the defined flow rate for a geometry of a flow through area of a flow control device; comparing the determined relationship of the performance parameter with the desired relationship; altering the geometry to a new geometry when the difference between the desired performance and the determined performance is outside a desired range; determining using the computer and the simulation program the relationship between the performance parameter and the selected property over the first range and the second range for the defined flow rate for the new geometry of the flow through area of the flow control device; repeating the process of altering the geometry and determining the performance until the difference between the desired performance and the determined performance for a geometry is acceptable; and storing the geometry of the flow through device on a suitable storage medium for which the difference between the determined performance and the desired performance is acceptable.

Method of providing a flow control device that substantially reduces fluid flow between a formation and a wellbore when a selected property of the fluid is in a selected range

In one aspect, a passive flow control device for controlling flow of a fluid is provided, which device in one configuration include a longitudinal member configured to receive fluid radially along a selected length of the longitudinal member, the longitudinal member including flow restrictions configured to cause a pressure drop across the radial direction of the longitudinal member. In another aspect, a method of completing a wellbore is provided, which method in one embodiment may include providing a flow control device that includes a tubular with a first set of fluid flow passages and at least one member with a second set of fluid passages placed outside the tubular, wherein the first and second set of passages are offset along a longitudinal direction and the member is configured to receive a fluid along the radial direction; placing the flow control device at a selected location a wellbore; and allowing a fluid flow between the formation and the flow control device.

Apparatus and method for controlling fluid flow between formations and wellbores

An apparatus for controlling flow of fluid from a reservoir into a wellbore is provided, which apparatus in one embodiment may include a flow-through region configured to substantially increase value of a selected parameter relating to the flow-through region when selected parameter is in a first range and maintain a substantially constant value of the selected parameter when the selected property of the fluid is in a second range.

Flow control device that substantially decreases flow of a fluid when a property of the fluid is in a selected range

A method of making a flow control device for controlling flow of fluid between a formation and a wellbore is provided, which method in one aspect may include: providing a member suitable for placement in a wellbore for receiving formation fluid; selecting a geometry for a flow-through region configured to substantially increase value of a selected parameter relating to the flow-through region when a selected property of the formation fluid is in a first range changes and maintain a substantially constant pressure drop across the flow-through region when the selected property of the fluid is in a second range; and forming the flow-through region on the member to provide the flow control device.
