A well servicing system includes a computer-based system that monitors pumping or other service operations at a well site and monitors deliveries and withdrawals of chemicals at a bulk storage station. A GPS device or other location identifier provides a location value that identifies the location of the service vehicle. A GPS reading is triggered by actuation of the vehicle's parking brake, and the location value is recorded in association with a process-related transducer value. The transducer value is based on the service vehicle performing some type of service operation either at the well site or at the bulk storage station.
