Title:
METHOD AND APPARATUS FOR SEALING TUBULARS
Document Type and Number:
WIPO Patent Application WO/2014/110523
Kind Code:
A3
Abstract:
A method of controlling fluid flow between two tubulars (110, 120) includes disposing a sealing member (130) in an annular area between two tubulars; moving the sealing member to a lower position where it is not in contact with one of the tubulars, thereby allowing fluid flow through the annular area; and moving the sealing member to an upper position where it is in contact with both of the tubulars, thereby preventing fluid flow through the annular area.
