A system for use in a wellbore intersecting a well zone comprises a tubular member 200 fixed in the wellbore, a first polished bore receptacle (PBR) 231 arranged within the tubular member above the well zone 204 and a second PBR 230 arranged within the tubular member below the well zone. Also provided is an outer tubing string 274 with a lower end open to establish communication between the axial bore of the tubing string and the wellbore and an inner tubing string 272 residing within the axial bore of the outer tubing string. A diverter tool 280 is connected to the lower end of the inner tubing string and has a port 282 for establishing flow between the axial bore of the inner tubing string and the wellbore. A first seal 277 is located on the outer tubing string and adapted to seal with the first PBR and a second seal 276 is located below the port of the diverter tool, the second sealing mechanism adapted to seal with the second PBR. The seal may be an O-ring, chevron seal, V-packed seal, bonded elastomer seal, compression seal, inflatable seal or face seal. |
