National Field Services (NFS), a subsidiary of Dudley Land Company, provides one point of contact for Right-of-WayEnvironmental, Renewable, and GIS services, something not offered by our competitors. In working with operators in every major basin, we have seen over and over how miscommunication between Land, Regulatory, and Operations negatively impacts project schedules and budgets. Our goal is to connect these three departments into a cohesive and efficient team. The NFS way of accountability, honest communication, and efficiency just makes sense.


Building upon Dudley Land Company’s 40 years of service to the oil and gas industry, NFS provides expanded services to our new and existing clients for their Pre-Construction, Construction, and Post-Construction needs.
