Patent ID: 7441605

Claim:
A production string assembly for producing hydrocarbon fluid from a wellbore comprising: a production nipple for placement proximate a production zone within the wellbore; a packer assembly for selectively forming a fluid seal within an annulus of the wellbore, the packer assembly having: a) a central tubular mandrel defining a flowbore to contain hydrostatic pressure; b) a packer element carried by the central mandrel, the packer element being moveable between an unset position and an axially compressed set position; c) a setting mechanism radially surrounding the central mandrel for moving the packer element to its set position in response to hydrostatic pressure within the flowbore; a wellbore condition sensor assembly having a monitor device and a linear sensor cable disposed generally upon the radial exterior of the production nipple and being disposed axially through the packer assembly; and a feed-through path defined axially through the mandrel, the feed-through path retaining the sensor cable in isolation from external fluid pressures.
