A tunable pneumatic fracturing system and process useable in some instances to extract oil and gas. Some embodiments provide a pneumatic fracturing tool with an elongated body that (a) contains (i) a propellant supply source intermediate opposed propellant gas discharge assemblies, (ii) a control system, and (iii) a communications port, and (b) has roller assemblies at opposed ends of the body. The tool can be tuned to provide gas pulse amplitudes and frequencies that react with the resonant frequency or other aspect of an adjacent earth formation. Some ...


1. A pneumatic fracturing process comprising: lowering a pneumatic fracturing tool into a well bore, the pneumatic fracturing tool comprising: a tool body having a gas jet section;a gas jet valve; anda gas jet opening in the gas jet section of the tool body;wherein the gas jet section is in fluid communication with the gas jet valve and faces outwardly from the tool body;burning solid fuel to generate pressurized gas;actuating the gas jet valve in accordance with a duty cycle to variably pulsate the pressurized gas through the gas jet opening toward a ro...
