Abstract: Disclosed is a downhole tool and method suitable for geosteering within a lateral formation. The downhole tool includes a gamma sensor for monitoring gamma radiation within the lateral formation. The method provides for monitoring of the location of the drill bit or a RSS within a borehole and correcting the angle of inclination to maintain the drill bit or RSS within the target zone of the lateral formation.

Abstract: A process where gas bubbles are produced under a partial vacuum and are dynamically agitated creating a vortex that allows for homogenization of the gas desired for dissolution into the affected aquifer. The technology is applied through installation of the apparatus into treatment wells. The treatment wells are installed as stand-alone wells where hydrogeological conditions are conductive, i.e. sandy aquifers, fractured bedrock aquifers, or in treatment cells where hydrogeological conditions are less conductive, i.e. saturated sediments that are clay rich. The system does not use a compressed gas, compressed air source, or forced air/gas through the use of compressors or blowers. Rather, it uses cavitation to produce a slight vacuum to draw gas or air through a snorkel apparatus that is attached to the gas mixing chamber of the unit. The unit is installed so that it is submerged in the treatment well below the water table.
