Abstract

The present invention provides for a method of enhancing access in an underground liquid reservoir by using a shaped charge in a well to create a rubble zone. The shaped charge explodes in manner as determined by the shape and design of the shaped charged. A practitioner of the invention can select the specific shaped charge or shaped charges to use, and the timing of placement of the shaped charges so that the resulting explosion produces a specific desired rubbled or rubble zone. The desired rubble zone in turn enhances or increases access to the liquid reservoir so that the rate and/or total amount of the liquid can be recovered from the reservoir is increased.
