Title:
LINER CEMENTATION PROCESS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/151303
Kind Code:
A3
Abstract:
Present embodiments are directed to coupling a cementation assembly (100) with a hung or set liner string in a well and moving the liner string during a cementation operation. Specifically, for example, a process in accordance with present techniques includes running a cementation assembly into a well on drill pipe and engaging, with a distal end of the cementation assembly, a liner top assembly (44) of a liner string (12) that is positioned downhole in the well, wherein the liner string was previously positioned downhole in the well without being cemented into the well. Further, the process includes latching the cementation assembly with the liner string such that movement of the cementation assembly is translated to the liner string, and flowing cement through the drill pipe and into the liner string while moving the cementation assembly and the liner string.
