ABSTRACT:
A bridge plug assembly 10 contracts radially inwardly to pass through tubing string T and then expands radially outwardly in response to axially compressive forces to set within a casing string C. Upper and lower independently moveable slips 52 and 54 of the anchor mechanism 12 engage casing C. The packoff mechanism 14 includes a plurality of upper sealing members 160, 162, 164 and a plurality of lower sealing members 166, 168, 170 having varying elasticity such that at least some of the sealing members overlap other sealing members when the bridge plug 10 is compression set in the casing C. The bridge plug assembly 10 is retained in a contracted position for passing downwardly through tubing T, then expanded for sealing engagement with casing C. The bridge plug 10 may be run-in with a setting tool ST and may be subsequently released by a releasing tool RT to drop within the well.
