Abstract
A high expandable straddle and a method of providing annular isolation at a location in a well bore. The straddle includes two expandable pipe sections with a base pipe section therebetween and end pipe sections for connection in a tubular string. The straddle may be run in tubing with restricted inner diameters and by the introduction of pressure to the saddle over 30% expansion can occur to the expandable pipe sections to seal and grip the tubing spanning a fault. An embodiment is described with the straddle being of unitary construction, the expansion pipe sections having thinned walls and being entirely formed of an austenitic stainless steel. An anchoring arrangement and/or seals may also be located on the expandable pipe sections.
