Open and Cased Hole Log Interpretation (PPH29)


    This interactive, applications-driven course will highlight the principles and applications of the main open and cased hole logging tools used in the oil industry. The course will explore the tools response explained from their physical principles as well as their relationship with the rock and fluid properties. Most common open hole and cased hole logging technologies will be covered explaining their main applications and limitations.

    This training course will feature:
    • Discussions on logging tools physical principles and applications
    • Tool limitations on different borehole environments
    • Tips and examples to identify and understand common logging issues
    • Explanation of petrophysical concepts and techniques for basic log interpretation
    • Cement and corrosion evaluation tools principles and applications
    • Cased hole resistivity, porosity and saturation tools
    • Application of interpretation methods in some examples and exercises

    Course Level: Skill
    Instructor: Angel Meso

    Designed for you, if you are...

    • An engineer in the exploration and production department
    • A geologist, geophysicist or petrophysicist
    • A petroleum, reservoir or drilling engineer
    • In general, any oil & gas industry professional involved in logging data interpretation and validation

    How we build your confidence

    This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented; the sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities. The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel.
