Tunable down-hole stimulation arrays feature closed-loop control of spatial arrays comprising several connected stimulators. Each stimulator is responsive to a timed activation signal. Stimulators periodically transmit bursts comprising a plurality of vibration frequencies, each burst having an adjustable power spectral density (PSD) that is tunable via an adjustable rebound cycle time. Rebound cycle times also affect vibration interference among array stimulators, while simultaneous or sequential timed activation signals from a programmable controller affect directional propagation of combined vibration wave fronts from an array. Stimulator PSD's are adjusted for resonance excitation and fracturing of adjacent geologic materials. Closed-loop feedback control incorporates backscatter vibration from stimulated geologic material. As fracturing proceeds to smaller (proppant-sized) fragments having higher resonant frequencies, PSD's are up-shifted, increasing relative power in higher vibration frequencies. Progressive geologic stimulation is optimized, with inherent potential for plain-water fracs completed with self-generated proppant.

An air and water/soap concentrate mixing device which creates high quality compressed air foam without restricting the flow of liquid through the apparatus. The device consists of three water/soap concentrate chambers, an air manifold and a central air diffuser tube. Water/soap concentrate flow is increased through the device from the entry chamber (first) thru the acceleration (second) chambers. Upon entering the deceleration (third) chamber, the water/soap concentrate perimeter is laced with pressurized air from the air manifold wrapping the acceleration chamber. At the same time, pressurized air is also diffused and embedded in the center of the water/soap concentrate flow via the air diffuser tube. As the accelerated water/soap concentrate enters the deceleration chamber, the flow is dramatically decreased. This slowing of the water/soap concentrate and the introduction of pressurized air causes a pressure volatility and turbulence inside the deceleration chamber allowing the pressures of the water/soap concentrate and air to equalize and mix creating foam bubbles. The device is also capable of flowing plain water or water/soap concentrate through the device if the pressurized air system or soap injection system is deactivated.
