ABSTRACT:
A packer tool for mounting on a work string in an oil and/or gas well is described. The packer is of the compression set type but includes a mechanism to prevent premature setting in the well. A method of running the tool with the completion is provided in order to advantageously allow an integrity test to be performed on the same run.
