    Description

    This course emphasises the criticality and application of Data Reconciliation to flow metering data. The basic principles covered will apply to all measured data which is required to be reconciled.

    Course Level: Foundation
    Duration: 3 days
    Instructor: Mohit Narain

    Designed for you, if you are...

    • A professional tasked with metering and measuring oil, gas and water in teams such as operations, technical services, safety, geology, reservoir engineering and oil & gas export.

    How we build your confidence

    • Highly interactive course
    • Practical examples will be presented and adequate exposure will be provided to the participants through exercises
    • The instructor is skilled in reconciling flow readings and experienced in training engineers on the basics of this application

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • Essence and importance of data reconciliation in metering
    • Common types of errors in metering
    • Weeding out irrelevant data
    • The technique of error minimisation and reconciliation of data
