Production Logging and Reservoir Monitoring (PPH04)

    Description

    This course covers all aspects of cased hole logging and interpretation, with particular emphasis on production logging and reservoir monitoring. The more you already think you know about cased hole logging and interpretation, the more you can expect to learn about what your logs are telling you about the behaviour of the well and the surrounding reservoir.

    Course Level: Intermediate / Advanced
    Instructor: Roger Nutt

    Designed for you, if you are...

    • A petroleum engineer or drilling manager
    • A petroleum, reservoir, drilling, production or wireline service company engineer, a petrophysicist, log analyst or technician
    • Someone who needs to understand what production logs and cased hole surveys can tell us about how the well and adjacent reservoir are behaving

    How we build your confidence

    You will learn by solving for yourself a host of real, practical and down-to-earth problems from a wide variety of wells and situations.
    The course includes an analysis of all the ways your casing can leak, why you can expect fluids to migrate behind the casing, all the data you need to have at your fingertips to interpret cased hole logs.
    You will learn how to interpret the wide variety of production and reservoir monitoring logs in vertical, deviated and horizontal wells.
    Cement bond log interpretation is both essential and difficult. However, this aspect of cased hole logging and interpretation will be subject to the expressed wishes and requirements of participants.

    The benefits from attending

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

    • How to integrate all the broad and subtle indications which your production and reservoir monitoring logs give you and understand what is happening inside your well and its environment
    • How to be sure where the different fluids which enter the casing are really coming from and where your injection gas or water is going
    • How much of the apparent behaviour of your well is caused by the reservoir as a whole - and how much is a result of unseen local disruptions to the flow pattern caused by the well and its surroundings
    • How much oil and gas are you leaving behind in the reservoir? (Perhaps most important of all)

    Topics

    • What data is needed for production logging and reservoir monitoring and how to set up and maintain the database
    • Why fluid migration through the casing-formation annulus is so common
    • Causes of casing damage and leaks
    • Production logging tools and principles
    • Flowmeters - how they work, what they measure
    • How apparent flow can be affected by the kind of perforation gun you use
    • How to recognise vortical flow
    • Bubble counter techniques
    • Temperature tools, and how to use them to identify flow behind the casing
    • Gradiomanometer and fluid density tools and their application
    • Water hold-up meters
    • Calipers
    • What the presence of NORM means, and how to use gamma-ray and spectral gamma-ray to identify it
    • How production logging tools are affected by deviation
    • Mono and multi-phase flow analysis
    • Porosity and water saturation determination through casing
    • TDT, principle and uses, qualitative and quantitative
    • C/O, Gamma spectroscopy logging
    • Time lapse monitoring of gas-oil and oil-water contacts and water saturation
    • Identifying by-passed oil and gas
    • Identifying the presence and speed of water flow behind the casing
    • Problems with horizontal wells and how to solve them
    • How to select the right tools and engineer the cased hole logging program
