Latest Patents

Nathan's latest patents include innovative methods for determining fracture proppant spatial distribution and fracture plane orientation using passive seismic signals. The first patent outlines a method for determining the spatial distribution of proppant by utilizing signals detected by seismic sensors placed near formations treated with fracturing fluid. This method involves determining the origin time and spatial position of seismic events induced by the fracturing process. It also includes calculating the volume and orientation of fractures associated with each seismic event, ultimately leading to a spatial distribution of the pumped fracturing fluid.

The second patent focuses on determining fracture plane orientation from seismic signals detected above a subsurface formation. This method employs an array of seismic sensors to detect signals during hydraulic fracture treatments. It involves determining the time and spatial position of microseismic events and selecting hypocenters that fall within a specific temporal sampling window. A best fit line through these selected hypocenters is then established using a preselected linear regression coefficient.
