Class Information
Number: 166/206
Name: Wells > Expansible anchor or casing
Description: Devices comprising (1) a means attached to a member which is run into a well conduit already in fixed position in the well, the means being movable outwardly to engage and jam against the surrounding conduit wall or to interlock in a preformed recess in the conduit, the means functioning to attach the member to the conduit in the well so as to resist action of gravity or a lifting force or (2) a section of casing which is expansible in the well.
