Abstract: Systems, devices, and methods including a processor having addressable memory, where the processor is configured to: determine one or more flight paths for an aerial vehicle, where the determined flight path creates a continuous surface about one or more potential gas sources of a survey site receive a trace gas data from one or more trace gas sensors of the aerial vehicle of the continuous surface as the aerial vehicle flies the determined one or more flight paths; and determine based on the received trace gas data whether a gas leak is present in the received survey site and a rate of the gas leak if present in the survey site.

Abstract: Systems, devices, and methods for an unmanned aerial vehicle (UAV); a trace gas sensor disposed on the UAV, where the gas sensor is configured to measure a gas point concentration; a wind sensor, where the wind sensor is configured to determine a discrete wind vector corresponding to the gas point concentration measurement; and where the discrete wind vector and gas point concentration measurement are acquired substantially concurrently and co-locally.

Abstract: Systems, devices, and methods including an aerial vehicle having a global positioning system (GPS) and at least one trace-gas sensor configured to generate gas data; and a processor having addressable memory, the processor configured to: determine a flight envelope based on a received spatial location, a received spatial location of the one or more potential gas sources, a received desired level of confidence, and a received wind data; determine a flight path for the aerial vehicle, where the flight path covers a portion of the determined flight envelope; and determine based on a received gas data whether a gas leak is present in the received spatial location to the received desired level of confidence.

Abstract: Systems, devices, and methods including receiving, by a processor having addressable memory, a spatial location of one or more known assets; determining, by the processor, one or more clusters based on the received spatial location of the one or more known assets; determining, by the processor, a bound for each asset of the one or more known assets in each cluster; and determining, by the processor, a flight plan for an aerial vehicle for each cluster, where the flight plan surveys each asset in each cluster.

Abstract: Systems, devices, and methods including a processor having addressable memory, the processor configured to: receive a trace-gas data packet, where the trace-gas data packet comprises a trace-gas concentration data from a trace-gas sensor and a location data for the trace-gas sensor from a location sensor, where the location data for the trace-gas sensor comprises a trajectory of the trace-gas sensor in space; receive at least one Meteorological data packet from one or more weather stations, where each weather station is distal from the trace-gas sensor, where each weather station generates a corresponding Meteorological data packet, where each Meteorological data packet comprises weather data; combine the trace-gas data packet with a selected spatial and temporal Meteorological data packet; and determine a trace-gas emission rate of a trace-gas source based on the combined trace-gas data packet and the selected Meteorological data packet.

Abstract: Improvements to base beams and self-propelled derrick rigs are described. The base beam can have two or more stabilizer arms which can be deployed. The base beam is also designed to support the derrick rig. An optional counterweight assembly can be connected to the front of the rig. The self-propelled derrick rig can be easily and quickly mounted to the base beam, and when mounted, the assembly will be able to withstand high hook loads and wind loading without the danger of the rig coming off of its wheels or falling over.
