Abstract: A system and a method for identifying a hydrocarbon sweet spot in a rock formation are disclosed. The method includes collecting a dataset comprising an elemental composition of one or more rock samples at various depths or locations, using an x-ray fluorescence device; analyzing the collected dataset of the one or more rock samples including analyzing the elemental composition of the one or more rock samples; establishing a time-correlative sample framework based on the collected dataset regarding the elemental composition of the one or more rock samples; performing a map-based spatial analysis comprising creating a distribution of concentration of one or more elements in the one or more rock samples in a geographical map generated within the framework; and identifying one or more locations of accumulation of hydrocarbons using the map-based spatial analysis.

Abstract: A method and apparatus of increasing the oxygen transfer rate, residence time, and circulation pathways within waste water is provided. The process uses cyclic bursts of compressed air to establish flow patterns within waste water. The flow patterns increase the residence time of air supplied by conventional aeration sources. The increased aeration facilitates the treatment of the waste water. Additional benefits which result from the process include increased mixing of the waste water along with additional aeration brought about from the cyclic air bursts.
