Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 43/11
E21B 29/00
E21B 33/12

US Classification:

166297, 166386, 166376, 166193, 166 55

Abstract:

A technique includes running a seat assembly on a conveyance line into a tubing string, which has previously been installed in a well. The seat assembly includes a seat, which is adapted to receive an untethered object. The technique includes attaching the seat assembly to the string at a location downhole in the well; receiving the object to create a fluid barrier; and diverting fluid using the fluid barrier.

Appl. No.:

13/348522

Inventors:

Jason Baihly - Katy TX, US
Don Aldridge - Manvel TX, US

International Classification:

E21B 43/25
E21B 34/00

US Classification:

166284, 166318

Abstract:

A technique provides a system and methodology for treating a plurality of zones, e.g. well zones. A plurality of flow control devices is located along a tubular structure, such as a well string in a wellbore. Each flow control device or each set of flow control devices comprises a seat member having a unique profile relative to the profiles of the other flow control devices. Drop objects are designed with engagement features arranged to engage the profiles of specific flow control devices. For example, each drop object may have an engagement feature of a corresponding profile designed to engage the unique profile of a specific flow control device or of a specific set of flow control devices to enable actuation of the specific flow control device or the specific set of flow control devices once the drop object is dropped through the tubular structure.
