ABSTRACT:
This invention uses a combination of drilling, dissolving, and sinking to emplace a closed end well pipe into a salt formation. The well which results can be used to produce geothermal power or for such other purposes for which it may offer an advantage. This method uses the following combination of properties of salt to achieve the desired result: solubility in water, plasticity at relatively low temperatures, and occurrence in large, deeply penetrating structures.
