A well packer isolation system (10) for use in hostile, corrosive environments is disclosed that comprises packer top sub (20), packer mandrel (22), setting sleeve (24), top slip support (26), slip (28), wedge (30), packer elements (32A, 32B, 32C), packer bottom sub (34), and shear pins (36, 38, 40, 42). As packer system (10) is run into an existing polished bore receptacle (12) using running tool (14), bottom sub (34) no-goes against PBR adapter sub (76). When sufficient setting pressure is exerted on setting sleeve (24) by running tool (14), shear pins (36, 38, 40) are sheared, packer elements (32A, 32B, 32C) are longitudinally compressed and radially expanded, and slip (28) engages inside wall (56) of PBR (12). Running tool (14) is withdrawn after packer system (10) is set by upwardly shearing shear pins (42).
