Abstract
An apparatus is provided which is connectable on a tubing string extendible into a subterranean well. The apparatus is selectively separatable whereby the tubing string may be parted. The apparatus comprises first means selectively retrievable from the apparatus for carrying across the apparatus a first weight load defined through the tubing string below the apparatus. Second weight load carrying means are provided for carrying across the apparatus a second weight load defined through the tubing string below the apparatus, the second weight load being less than the first weight load. The second means are activatable to separate the apparatus and the tubing string when the second weight load is exceeded.
