1. A method of releasing a packer or bridge plug, comprising:
delivering a telescoping grip tool in a first configuration to engage the packer or bridge plug at a first location;
equalizing pressure across the set packer or bridge plug with upward movement of said telescoping grip tool applying a tensile force to the packer or bridge plug;
telescoping said telescoping grip tool into a second configuration by increasing a length of said telescoping grip tool after said equalizing and while engaged to the packer or bridge plug at said first location;
engaging a second location on said packer or bridge plug after said telescoping with non-rotational axial movement of said telescoping grip tool in said second configuration;
releasing said packer or bridge plug after said equalizing with movement of said telescoping grip tool in said second configuration.
