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 15):
The field created integral electrically isolated centralizer and swell packer system of  claim 1 , wherein the tubular swellable material comprises either:\n a. an oil-swellable rubber, a natural rubber, a polyurethane rubber, an acrylate/butadiene rubber, a butyl rubber (IIR), a brominated butyl rubber (BIIR), a chlorinated butyl rubber (CIIR), a chlorinated polyethylene rubber (CM/CPE), an isoprene rubber, a chloroprene rubber, a neoprene rubber, a butadiene rubber, a styrenebutadiene copolymer rubber (SBR), a sulphonated polyethylene (PES), chlor-sulphonated polyethylene (CSM), an ethylene/acrylate rubber (EAM, AEM), an epichlorohydriniethylene oxide copolymer rubber (CO, ECO), an ethylene/propylene copolymer rubber (EPM), ethylene/propylene/diene terpolymer (EPDM), a peroxide crosslinked ethylene/propylene copolymer rubber, a sulphur crosslinked ethylene/propylene copolymer rubber, an ethylene/propylene/diene terpolymer rubber (EPT), an ethylene/vinyl acetate copolymer, a fluoro silicone rubber (FVMQ), a silicone rubber (VMQ), a poly 2,2,1-bicyclo heptene (polynorbornene), an alkylstyrene polymer, a crosslinked substituted vinyl/acrylate copolymer, derivatives thereof, or combinations thereof; or b. a water-and-oil-swellable material, and wherein the water-and-oil-swellable material comprises a nitrile rubber (NBR), an acrylonitrile/butadiene rubber, a hydrogenated nitrile rubber (HNBR), a highly saturated nitrile rubber (HNS), a hydrogenated acrylonitrile/butadiene rubber, an acrylic acid type polymer, poly(acrylic acid), polyacrylate rubber, a fluoro rubber (FKM), a perfluoro rubber (FFKM), derivatives thereof, or combinations thereof.
