1. A packer system, comprising:
a packer mandrel having an upper mandrel end and a lower mandrel end;
an upper support ring at said upper mandrel end;
a seal member having an upper seal end and a lower seal end opposite said upper seal end, said seal member having a run-in position with a run-in diameter and a set position with set diameter, said set diameter being larger than said run-in diameter so as to seal against a borehole;
an upper slip device having an upper support ring end, an upper cone end opposite said upper support ring end, and an initial upper slip position with said seal member in said run-in position, said upper slip device being between said upper support ring and said upper seal end;
an upper cone having an upper slip end and an upper sealing end opposite said upper slip end, said upper sealing end positioned so as to exert pressure at said upper seal end on said seal member, said upper slip device being in sliding engagement with said upper cone and having an upper slip engaged position with said seal member in said set position;
a lower cone having a lower slip end and a lower sealing end opposite said lower slip end, said lower sealing end positioned so as to exert pressure at said lower seal end on said seal member;
a lower slip device having a lower setting sleeve end, a lower cone end opposite said lower setting sleeve end, and an initial lower slip position with said seal member in said run-in position, said lower slip device being in sliding engagement with said lower cone and having a lower slip engaged position with said seal member in said set position;
a setting sleeve having a lower cone engagement end and a setting piston end opposite said lower cone engagement end, said setting sleeve being mounted on said packer mandrel and being between said packer mandrel and said lower slip device; and
a setting piston having a setting end in removeable engagement with said setting piston end of said setting sleeve so as to apply pressure on said setting sleeve to said lower cone, said lower slip being between said setting piston and said lower cone.
