Washpipe Isolation Valve And Associated Systems And Methods
US Patent:
2013033, Dec 19, 2013
Filed:
Aug 22, 2013
Appl. No.:
13/973368
Inventors:
Gary J. GEOFFROY - Plano TX, US
Assignee:
Halliburton Energy Services, Inc. - Houston TX
International Classification:
E21B 43/04, E21B 34/12
US Classification:
166278, 166373
Abstract:
A method can include closing a valve interconnected between sections of a washpipe of a service tool string by displacing the service tool string relative to a completion string, thereby preventing flow through the washpipe. A well system can include a service tool string reciprocably received in a completion string, the service tool string including a washpipe received in a well screen, and a valve which selectively permits and prevents flow through the washpipe. The completion string can include a structure which operates the valve in response to displacement of the service tool string relative to the completion string. Another method can include closing a valve by partially withdrawing a service tool string from a completion string, thereby preventing flow through a washpipe of the service tool string.
