1. An apparatus for managing an intelligent field, the apparatus comprising: a plurality of hydrocarbon well instruments, the well instruments comprising: a permanent downhole monitoring system (PDHMS), a multiphase flow meter (MPFM), a wellhead pressure (WHP) and wellhead temperature (WHT) measurement device, a tubing or casing annulus (TCA) pressure measurement, and optionally an electrical submersible pump (ESP) when desired; a supervisory control and data acquisition (SCADA) system for an intelligent hydrocarbon recovery field system, the SCADA system operably coupled to the plurality of well instruments to receive data therefrom; a process integration (PI) server for the intelligent field system, the PI server operably coupled to the SCADA system to receive data therefrom; a dynamic field data analyzing computer including a processor and memory coupled to the processor, the dynamic field data validity analyzing computer operably coupled to the PI server to receive data therefrom; and dynamic field data analyzing program code stored in the memory of the dynamic field data analyzing computer and including instructions that when executed by the dynamic field data analyzing computer, cause the computer to perform the operations of: receiving at least substantially real-time dynamic field data for the intelligent field system, the at least substantially real-time field data comprising one or more well instrument data values for each of the plurality of well instruments, analyzing validity of the dynamic field data, the analysis including comparing the one or more well instrument data values for at least one of the plurality of well instruments to validation criteria associated therewith, validating the one or more well instrument data values for the at least one well instrument when the respective one or more well instrument data values fall within the respective validation criteria, and flagging the one or more well instrument data values for the at least one well instrument when the respective one or more well instrument data values fall outside the respective validation criteria.
