Abstract:
A field created integral electrically isolated centralizer and swell packer system for wellbore tubulars having in series over the wellbore tubular, a first end ring, a swell packer portion over a first and second primer optionally with cured resin, a second end ring, wherein the end rings inhibit axial movement of the swell packer portion. Integral with the swell packer portion an electrically isolating centralizer; a cured resin bonded to the wellbore tubular filling all hollow spaces of the centralizer portion integrally forming a high strength bond, while excluding bonding to the first and second end rings, the cured resin configured to cure to a hardness of at least 50 shore A and withstand temperatures and pressures within a wellbore for at least twenty-four hours without melting, while specifically excluding a sand screen.

Claim (Index 1):
A field created integral electrically isolated centralizer and swell packer system as an integral assembly comprising:\n i. a wellbore base tubular having a box end and a pin end; ii. a first end ring with a first end ring inner diameter slightly smaller than a box end inner diameter, the first end ring mounted adjacent the box end around the wellbore base tubular; iii. a swell packer portion comprising:\n 1) a first primer disposed on the wellbore base tubular adjacent the first end ring; \n 2) a cured resin formed from a liquid phase injectable material disposed on the first primer; and \n 3) a tubular swellable material disposed on the cured resin, the tubular swellable material having a swellable material inner diameter slightly less than the first end ring inner diameter, the tubular swellable material selected to expand on exposure to at least one triggering fluid used in the wellbore forming a seal in the wellbore upon expansion; the tubular swellable material mounted to the first end ring over the first primer; \n iv. a second primer disposed on the wellbore base tubular as part of the swell packer portion; v. a second end ring disposed on the second primer and around the wellbore base tubular securing to the swell packer portion opposite the first end ring, wherein the first and second end rings inhibit axial movement of the swell packer portion on the wellbore base tubular; vi. an electrically isolating centralizer portion mounted over the wellbore base tubular, the electrically isolated centralizer portion configured to centralize the wellbore base tubular in a production liner in a wellbore, the electrically isolated centralizer portion comprising:\n 1) hollow tube with fill port and at least one exit port having an outer surface; \n 2) a plurality of blades extending from the outer surface, each blade positioned over a thru-hole; \n 3) a cured resin bonded to the wellbore base tubular filling all hollow spaces integrally forming a high strength bond between the wellbore base tubular and the hollow tube, while excluding the first and second end rings, the cured resin configured to cure to a hardness of at least 50 shore A and withstand temperatures and pressures within a wellbore for at least twenty-four hours without melting, the formed integral electrically isolated centralizer and swell packer system specifically excluding a sand screen in the field created integral formed system.
