Abstract:
1. A method for setting a packer in a wellbore, the method comprising: providing a packer having a packer mandrel with a seal assembly and a piston slidably disposed thereabout; running the packer into the wellbore; resisting a force acting on the piston generated by a pressure difference between pressure in the wellbore and pressure in a chamber defined between the piston and the packer mandrel by restraining movement of the piston toward the seal assembly with a release assembly; actuating the release assembly responsive to contact with a profile in the wellbore; and responsive to the pressure difference, longitudinally shifting the piston relative to the packer mandrel toward the seal assembly, to operate the seal assembly from a running position to a radially expanded sealing position, thereby setting the packer.
