    Abstract: A zonal isolation device (10; 20; 30; 300; 400; 500; 600) in the form of an active external casing packer is provided which includes a tubular section such as a casing or liner (1; 21; 31; 171; 203) arranged to be run into and secured within a larger diameter generally cylindrical structure such as an open borehole (163; 213). At least one sleeve member (3; 23; 33; 43; 173) is positioned on the exterior of the casing or liner and is sealed thereto and at least two deformable band members (201; 401, 403; 501) are provided around and are bonded to the outer circumference of the sleeve member. The sleeve member and the at least two deformable band members is/are expanded into place against the inner circumference of the open borehole by increasing the pressure within the sleeve member. The method detailed herein also provides zonal isolation by use of a pair of spaced apart sleeve members during a frac operation where frac fluid is supplied to a zone (in between the pair of sleeve members) requiring to be frac'd, where the frac pressure acts not only on the outside of the zonal isolation device but also on the interior of the sleeve member to enhance the seal provided thereby.

    Abstract: A method of anchoring tubing in a bore comprises: providing first tubing having a section with a wall configured to provide outer surface portions describing a diameter less than a first diameter. The tubing is located within a bore comprising a first section having an internal diameter greater than the first diameter and a second section having an internal diameter corresponding to the first diameter, with the tubing section in the first section of the bore. The tubing section is then reconfigured such that the outer surface portions describe a tubing diameter greater than the first diameter. The tubing is then axially translated relative to the bore to locate the tubing section in the second section of the bore such that the outer surface portions are restrained to the first diameter by the bore, and the outer surface portions engage with the bore.
