US Patent 10920540 Reducing noise produced by well operations

A method for reducing noise produced by well operations includes obtaining a list of equipment performing the well operations in an open-air environment. The method further includes obtaining a mapping between engine rotations-per-minute (“RPM”), load, and noise produced by a combination of the equipment. The method further includes selecting a set point comprising gear number and engine speed, respectively for each engine, that minimizes the noise produced for the combination of the equipment based on the mapping. The method further includes adjusting each engine driving the well operations to operate at the respective set point.
