Latest Patents

One of Gilstad's latest inventions is an Adaptive Stimulation System. This technology combines impulse-generated swept-frequency stimulation vibrations with cyclically varying hydraulic pressure to enhance adaptive down-hole stimulation. The system utilizes cyclical shifts in the power spectral density (PSD) of each stimulator's fluid interface vibration through closed-loop control of the rebound cycle time. The PSDs are meticulously adjusted to promote resonance excitation and facilitate the fracturing of geologic materials at varying distances from a wellbore. As fracturing progresses, the system optimizes stimulation by up-shifting PSDs, thereby increasing stimulation vibration power at higher frequencies. This advancement supports efficient operations with plain water or liquefied propane fracs, effectively utilizing self-generated proppant.
