A Data Historian (also known as a Process Historian or Operational Historian) is a software program that records and retrieves production and process data by time; it stores the information in a time series database that uses minimal disk space and enables fast retrieval. Time series information is often displayed in a trend or as tabular data over a time range (e.g.. the last day, last 8 hours, last year).

There are many uses for a Data Historian in the Oil & Gas industries:

  • Manufacturing site to record instrument readings
    • Process (ex. flow rate, valve position, vessel level, temperature, pressure)
    • Production Status (ex. machine up/down, downtime reason tracking)
    • Performance Monitoring (ex. units/hour, machine utilization vs. machine capacity, scheduled vs. unscheduled outages)
    • Product Genealogy (ex. start/end times, material consumption quantity, lot # tracking, product set points and actual values)
    • Quality Control (ex. quality readings inline or offline in a lab for compliance to specifications)
    • Manufacturing Costing (ex. machine and material costs assignable to a production)
  • Utilities (ex. Coal, Hydro, Nuclear, and Wind power plants, transmission, and distribution)
  • Heavy Equipment monitoring (ex. recording of run hours, instrument and equipment readings for predictive maintenance)
  • Environmental monitoring (ex. weather, sea level, atmospheric conditions, ground water contamination)

Information collected within a facility can come from many different types of sources including:

  • PLCs (Programmable Logic Controllers) that control a finite part of the process (ex. one machine or one processing unit)
  • DCS (Distributed Control System) that could control an entire facility
  • Proprietary Instrument Interface (ex. Intelligent Electronic Devices): data delivered directly from an instrument instead of a control system (ex. Weighing system, clean-in-place skid).
  • Lab Instrument (ex. Spectrophotometer, TOC Analyzer, Resonance Mass Measurement)
  • Manual Data Entry (ex. an operator periodically walks the production line and records readings off manual gauges)

A data historian could be applied independently in one or more areas, but it can really show its worth when applied across an entire facility, many facilities in a department and across departments within an organization.
