Our wireline fleets have always been designed for optimizing recovery from and servicing of wells in challenging and unconventional areas. Pioneer specializes in shale-ready units with greaseless electric wireline for further depths and longer laterals. Our EcoQuiet units were developed in response to a much different challenge: operating near populated urban areas without disturbing residents. 

Completions operations are often cordoned off with physical methods like soil berms or hay bales, which can partially reduce environmental noise. But these physical barriers can be unsightly, difficult to relocate and not always effective. For our EcoQuiet units, our engineers sought an effective technical solution - designing units that operate effectively while minimizing vibration and noise. 

Ultimately, reductions in noise and vibration from drilling operations that utilize our EcoQuiet technology result in reductions in the disturbance to property owners at minimal setback distances - allowing for efficient operations without inconveniencing residents. It's a win-win solution that allows our clients to be good neighbors to the communities in which they operate.
