IMPROVED ISOLATION BARRIER |
摘要 |
An apparatus (10) and method for securing a tubular (12) within another tubular or borehole (80), creating a seal across an annulus in a wellbore (80), and centralising or anchoring tubing within a wellbore. A sleeve (14) is arranged on a tubular body (12) to create a chamber (16) therebetween. A port (18) provides fluid access through the body to the chamber. The chamber is filled with a swellable material (20). Thus the sleeve can be morphed to secure it to a well bore wall by the use of fluid pressure and an activated swellable material, the swellable material being used to support the sleeve to maintain a seal between the sleeve and well bore wall to form an isolation barrier. |
