Remotely controllable variable flow control configuration and method

Abstract

A remotely controllable flow control configuration including a body; one or more flow restrictors disposed in the body; and a selector fluidly connected with the body and capable of supplying or denying fluid to one or more of the one or more flow restrictors and method.

Description

[0001] Cross References to Related Applications [0002] This invention contains subject matter related to subject matter of a co-pending application assigned to the same assignee as the present application, Baker Hughes Company of Houston, Texas, USA. The applications listed below are hereby incorporated by reference in their entirety. [0003] The U.S. patent application titled "REMOTELY CONTROLLABLE MANIFOLD" filed on July 2, 2009, with agency docket number 274-49269-US (BAO0340US). Background technique [0004] In a fluid flow system, a balance of fluid flow characteristics is necessary in order to optimize the system. An example of this is in the downhole drilling and completion industry where fluids flowing from or out of a subterranean formation into a wellbore are subjected to fingering due to the formation's varying permeability and frictional pressure drop. These devices, which have traditionally been attempted to control flow characteristics, are known in the art ...

AI Technical Summary

Problems solved by technology

These devices work well for their intended purpose, but they are fixed tools that must be positioned in the completion at the time of construction and replacement requires removal of the completion

It is familiar to those skilled in the art that this operation is expensive

However, correcting property failures is also costly, as for interdigitated production wells, undesired fluid production is experienced, and for injection wells, injection fluid may be lost into the formation

There is also a lack of operational efficiencies for other types of wellbore systems
