Abstract
An apparatus for providing zonal isolation in a wellbore includes a plurality of interlocking sealing elements having anchor elements at the opposing ends. Each anchor element sealingly engages a wellbore tubular whereas the interlocking sealing elements do not engage any portion of wellbore therebetween. In one exemplary application utilizes a wellhead and lubricator positioned over a wellbore under pressure and a conveyance device for conveying equipment into the wellhead. The first anchor, the second anchor and the plurality of interlocking sealing elements are separately conveyed into the wellbore with the conveyance device and sequentially assembled in the wellbore to provide zonal isolation.
