Title: Packer arrangements for oil wells and the like

Abstract

The packer includes an elongated tubular casing, and a metal ring is disposed in its entirety within an annular recess in the casing. The recess has a circumferential opening extending entirely around the peripheral outer surface of the casing. Hydraulic fluid is flowed into the recess to apply pressure to the inner peripheral surface of the metal ring to expand the ring radially outwardly and force its outer peripheral surface through the circumferential opening and into annular sealing engagement with the opposed surface of the well casing.
