Abstract: A real-time silica monitoring system can include a plurality of off-site sensors positioned at geographic locations off-site from a hydraulic fracturing well site that detect and measure quantities of airborne silica particles, a plurality of on-site sensors positioned at geographic locations on a hydraulic fracturing well site that detect and measure quantities of air-borne silica particles, and one or more mobile sensors suitable to be carried by individual persons that detect and measure quantities of airborne silica particles. A monitoring system can include a computer system that can aggregate and store airborne silica measurements taken by one or more sensors and communicate data to a user.

Abstract: A system and method for monitoring and predicting a gas leak at a facility involving receiving, via a server, real-time data measured via a plurality of sensors spaced throughout a facility; scrubbing, via the server, the real-time data by removing a plurality of spikes, a plurality white noise, or a combination thereof, from the real-time data to yield a set of scrubbed data; determining a gas leak location within the facility based on the scrubbed data; conducting a gas leak simulation based on the scrubbed data; determining a potential gas leak distribution based on the scrubbed data and the gas leak simulation; calculating a risk profile based on a set of predetermined risk parameters; generating a notification based on the potential gas leak distribution and the risk profile; and transmitting over a network, the risk profile and the potential gas leak distribution to at least one mobile device.
