ABSTRACT:
Disclosed herein is a method and apparatus for setting a compression seal pack in a well without rotation of the pipe string and setting mandrel. The setting device includes a release device and a moveable member. The release device secures a setting mandrel in a non-engaged position with respect to the seal packer. The moveable member is positionable to a first position, where the setting mandrel is locked in its non-engaged position, and to a second position, where the release device is free and the setting mandrel may move with respect to the seal packer. The method disclosed herein includes coupling the setting device to a compression set packer, positioning a setting mandrel within the seal packer and setting device, positioning the seal packer at the desired location in a well, releasing the setting mandrel from its non-engaged position with respect to the seal packer and lowering the setting mandrel into engagement with said packer to set the packer in the well.
