  • Hydraulically activated selective circulating/reverse circulating packer assembly
    Patent number: 6554076
    Abstract: The present invention relates to packers adapted to seal an annular space within a wellbore. The packers, for example, may be utilized to circulate or reverse circulate a fluid. In one embodiment, the present apparatus comprises a first tubular subunit and a second tubular subunit moveably coupled together, a flexible packing element disposed between the first tubular subunit and the second tubular subunit, and a temporary mechanical connection adapted to restrain the first tubular subunit and the second tubular subunit from compressing the flexible packing element, in which the temporary mechanical connection is adapted to be hydraulically disengaged. In another embodiment, the present apparatus further comprises a valve. The valve may be selectively opened to allow fluid to flow between the annular space and the central bore of the valve.
