Underground sequestration system and method in which a liquid or gas is stored in a sequestration zone of enhanced porosity in an underground geological formation, with a containment barrier around the sequestration zone. Conditions within the formation are monitored to verify the integrity of the sequestered substance, and any necessary repair or maintenance is done through wells that extend into the formation. In some disclosed embodiments, the porosity of the formation in the sequestration zone is enhanced by boreholes and laterals that are drilled with high velocity hydraulic cutting jets, and the sequestered liquid or gas is injected into the sequestration zone through the boreholes and laterals. Additional boreholes and laterals are employed in the containment barrier, and the barrier is formed of a thixotropic material that is injected into the formation through the additional boreholes and laterals.
