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 from the plurality of well instruments; a process integration (PI) server for the intelligent field system, the PI server operably coupled to the SCADA system to receive data from the SCADA system; a dynamic field data analyzing computer including a processor and memory coupled to the processor, the dynamic field data analyzing computer operably coupled to the PI server to receive data from the PI server; 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 real-time dynamic field data for the intelligent field system, the 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 to determine whether one or more of the well instrument data values fall within respective validation criteria; in response to determining that one or more of the well instrument data values fall within the respective validation criteria, validating the one or more well instrument data values that fall within the respective validation criteria; in response to determining that one or more of the well instrument data values fall outside the respective validation criteria: flagging the one or more well instrument data values that fall outside the respective validation criteria for the at least one well instrument; determining whether the one or more well instrument data values that fall outside the respective validation criteria are reliable; in response to determining the one or more well instrument data values that fall outside the respective validation criteria are reliable, generating an alert indicating the that the one or more well instrument data values are reliable and invalid; and in response to determining the one or more well instrument data values that fall outside the respective validation criteria are unreliable, generating a report indicating the that the one or more well instrument data values are unreliable and invalid.
