Abstract: Disclosed herein are systems and methods for detecting a gas leak at a field site, the system having at least one gas sensor, an acoustic sensor, and a processing unit having a processor and a non-transitory computer readable storage media storing instructions, the processing unit configured to receive signals from the at least one gas sensor and the acoustic sensor. When the instructions are executed by the processor of the processing unit, the signals received from the at least one gas sensor and the acoustic sensor are analyzed to determine a presence of a gas leak, the presence of the gas leak determined if at least one signal received from the gas sensor is above a first gas threshold value and at least one signal received from the acoustic sensor is above a first acoustic threshold value.
