ABSTRACT:
A device and method and/or system for generating pulses to improve drilling rates, the ability to drill straighter and farther by increasing fracturing or injection efficiencies in a geological formation that may contain desirable hydrocarbons. This system can be used in other types of drilling or fracturing operations, whether to unclog arteries or to open formations for underground storage in conjunction with pulsing/fracturing and create large pulses downhole for seismic purposes. The system and method comprises several pulse generating devices longitudinally and axially positioned within upper, middle, lower, and outer annular drill collar flow channels or packer isolation mechanisms such that the PFD medium flows through the various annular drill collar flow channels and the PFD medium is guided into one or more sets of selectively reversible flow connecting channels, wherein the connecting channels are connected to guide pole channel allowing for controlling pulsing within the geological formation.
