Minimizing Noise

Noise created by operators constantly driving in and out from the well pad to monitor well production can be mitigated using an automated monitoring system, which allows wells to be monitored remotely, e.g., from the company's office. [1]

To mitigate noise impacts from engines, a sound barrier made out of four inches of insulation and 18-gauge steel can be used. Sound barriers are placed in an L-shape above the engine, and they extend past the sides of the engine.[2] Some engines can operate at a constant number of revolutions per minute (RPM), which reduces the updown noise caused by other engines, which speed up and slow down. Mufflers, like those used for automobile engines, can be used to minimize engine noise.[3] To reduce noise in sensitive areas, well-site or field compressors may be enclosed in a sound-insulated building, and equipped with two buried hospital-grade mufflers in series.

Noise from compressors can be mitigated by treating each significant noise source: gas turbines or engines, compressors, exhaust outlets and air inlets, and cooling and ventilation fans. Abatement may involve changing the blades on fans, which can change the frequency of sound emitted, thereby removing the annoying tones. Engine noise can be muffled using automotive-type mufflers, or by housing the engines inacoustically insulated structures. Also, the entire compressor can be housed in an acoustically insulated building.
