Methods of and apparatus for completing multiple zone wells

Claim 1

THE METHOD OF COMPLETING A MULTIPLE ZONE WELL WHICH INCLUDES, CONNECTING A LOWER HYDRAULICALLY-ACTUATED WELL PACKER TO THE LOWER END OF A FIRST PRODUCTION STRING AND LOWERING SAID PACKER AND STRING A PREDETERMENED DISTANCE WITHIN THE WELL BORE, THE LOWER END OF SAID FIRST PRODUCTION STRING COMMUNICATING WITH THE AREA BELOW THE LOWER PACKER, THEN CONNECTING A HYDRAULICALLY-ACTUATED INTERMEDIATE WELL PACKER TO SAID FIRST PRODUCTION STRING AND CONTINUING THE LOWERING OF SAID FIRST STRING AND PACKERS, LOWERING A TUBULAR CONDUCTOR INTO THE WELL AND CONNECTING THE LOWER END THEREOF TO THE INTERMEDIATE PACKER TO EXTEND UPWARDLY THEREFROM, THE LOWER END OF SAID CONDUCTOR COMMUNICATING WITH THE AREA BETWEEN THE LOWER AND INTERMEDIATE PACKERS, THEREAFTER CONNECTING AN UPPER HYDRAULICALLY-ACTUATED PACKER TO SAID FIRST PRODUCTION STRING AND ALSO COUPLING THE UPPER PACKER TO SAID TUBULAR CONDUCTOR, THEN FURTHER LOWERING THE FIRST PRODUCTION STRING, PACKERS AND CONDUCTOR TO LOCATE SAID PACKERS IN FINAL POSITION WITHIN THE WELL BORE, THEN RUNNING THE UPPER PORTION OF A SECOND PRODUCTION STRING AND RELEASABLY CONNECTING IT TO THE UPPER PACKER TO COMMUNICATE WITH THE TUBULAR CONDUCTOR, SAID UPPER PORTION OF THE SECOND STRING AND THE TUBULAR CONDUCTOR FORMING THE COMPLETE SECOND PRODUCTION STRING, RUNNING A THIRD PRODUCTION STRING AND RELEASABLY CONNECTING IT WITH THE UPPER PACKER TO COMMUNICATE WITH THE AREA BETWEEN THE UPPER AND INTERMEDIATE PACKERS, LANDING ALL PRODUCTION STRINGS IN FINAL POSITION IN THE WELL BORE, AND THEREAFTER SETTING ALL HYDRAULICALLYACTUATED WELL PACKERS BY APPLYING A PRESSURE THERETO FROM THE BORES OF THE PRODUCTION STRINGS.

Claim 2

THE METHOD OF COMPLETING A MULTIPLE ZONE WELL WHICH INCLUDES, CONNECTING A LOWER HYDRAULICALLY-ACTUATED WELL PACKER TO THE LOWER END OF A FIRST PRODUCTION STRING AND LOWERING SAID PACKER AND STRING A PREDETERMENED DISTANCE WITHIN THE WELL BORE, THE LOWER END OF SAID FIRST PRODUCTION STRING COMMUNICATING WITH THE AREA BELOW THE LOWER PACKER, THEN CONNECTING A HYDRAULICALLY-ACTUATED INTERMEDIATE WELL PACKER TO SAID FIRST PRODUCTION STRING AND CONTINUING THE LOWERING OF SAID FIRST STRING AND PACKERS, LOWERING A TUBULAR CONDUCTOR INTO THE WELL AND CONNECTING THE LOWER END THEREOF TO THE INTERMEDIATE PACKER TO EXTEND UPWARDLY THEREFROM, THE LOWER END OF SAID CONDUCTOR COMMUNICATING WITH THE AREA BETWEEN THE LOWER AND INTERMEDIATE PACKERS, THEREAFTER CONNECTING AN UPPER HYDRAULICALLY-ACTUATED PACKER TO SAID FIRST PRODUCTION STRING AND ALSO COUPLING THE UPPER PACKER TO SAID TUBULAR CONDUCTOR, THEN FURTHER LOWERING THE FIRST PRODUCTION STRING, PACKERS AND CONDUCTOR TO LOCATE SAID PACKERS IN FINAL POSITION WITHIN THE WELL BORE, THEN RUNNING THE UPPER PORTION OF A SECOND PRODUCTION STRING AND RELEASABLY CONNECTING IT TO THE UPPER PACKER TO COMMUNICATE WITH THE TUBULAR CONDUCTOR, SAID UPPER PORTION OF THE SECOND STRING AND THE TUBULAR CONDUCTOR FORMING THE COMPLETE SECOND PRODUCTION STRING, RUNNING A THIRD PRODUCTION STRING AND RELEASABLY CONNECTING IT WITH THE UPPER PACKER TO COMMUNICATE WITH THE AREA BETWEEN THE UPPER AND INTERMEDIATE PACKERS, LANDING ALL PRODUCTION STRINGS IN FINAL POSITION IN THE WELL BORE, AND THEREAFTER SETTING ALL HYDRAULICALLYACTUATED WELL PACKERS BY APPLYING A PRESSURE THERETO FROM THE BORES OF THE PRODUCTION STRINGS.
