ABSTRACT:
Method and apparatus for completing a plurality of zones in a wellbore. A packer having a tubular element extending therethrough is suspended in a wellbore between two hydrocarbon-bearing zones of interest. The lower zone is perforated and stimulated if necessary. Thereafter, the tubular element is sealed with a plug which includes an explosive charge and the upper zone is fractured and stimulated. The explosive is then detonated thus severing the tubular element at the plug thereby permitting production of formation fluids from both zones into a common string of tubing.
