Introduction to Petroleum Prospect Appraisal (GEO25)


    This course provides an introduction on how to identify, map, describe and risk a prospect, assess its volumetrics and propose it to management for drilling. It takes you along the path followed by all oil company geoscientists involved in the evaluation of acreage.

    Course Level: Foundation
    Instructor: Daniel Clark-Lowes

    Designed for you, if you are...

    • A geoscientist with one to ten years of experience
    • A petroleum engineer or economist wishing to broaden your knowledge of the business

    How we build your confidence

    • Learning is by way of a mixture of lectures and exercises. Numerous actual examples are used throughout the course to illustrate the points covered
    • Exercises are used to reinforce understanding of points explained in lectures and emphasis is on discussing and supporting interpretations. Exercises include assessment of values, and ranges of values, for gross rock volume, net to gross, porosity, hydrocarbon saturation and formation volume factor/ gas expansion factor for input to Monte Carlo probabilistic models
    • The interactive discussion sessions that follow both formal teaching and exercises are considered particularly important. Learning is as much by open discussion with course instructor and classmates, as it is by formal instruction

    The benefits from attending

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

    • How to assess subsurface well, laboratory and seismic data to establish prospectivity
    • How to use the principles of play fairway and petroleum system analysis to improve understanding of prospectivity
    • How to identify and map leads and prospects within petroleum basins and play fairways
    • How to evaluate risk prospects based on assessment of chance of finding a suitable reservoir / seal pair; charge from mature source kitchen; migration conduit and trap that was created prior to charge
    • How to establish a probability range of resources / reserves using Monte Carlo probabilistic procedures from input parameters including gross rock volume, net to gross, porosity, hydrocarbon saturation, formation volume factor / gas expansion factor and recovery factor
    • How to present a prospect to management as an investment opportunity
    • How to evaluate a second prospect before and after the first is drilled


    • Collection, assessment and presentation of data
      - Subsurface well data
      - Seismic surveys and other geotechnical tools
      - The identification of prospects and their evaluation (risking and volumetrics)
      - Presentation to management
    • Evaluation of acreage
      - Play fairway and petroleum system analysis techniques
    • Petroleum geology topics
      - Reservoir / seal pairs
      - Charge, migration and entrapment from source kitchen to trap
      - Trap parameters including timing
    • Basic probabilistic theory - to provide a background to prospect risking and determination of ranges of in-place petroleum resources
    • Prospect resource probability
      - Gross rock volume
      - Net to gross
      - Porosity
      - Hydrocarbon saturation
      - Formation volume factor / gas expansion factor
      - Recovery factor
