    Course Overview:

    Unconventional reservoir petrophysical Parameters, shale volume, porosity, lithology, water saturation and permeability methodologies will be studied in this course. The core measurements and heavy oil effects on the core measurements will be discussed.

    This course will help to give the participants better understanding of log interpretation concepts basic of interpretation techniques for evaluation of unconventional reservoirs.

    The role of petrophysics in unconventional reservoir characterization study and its interaction with other disciplines will be demonstrated.


    Specially Designed For:

    For unconventional reservoirs using wrong log analysis methods will be produced silly results, so the course will be guide to understand what type of unconventional reservoir petrophysicists are dealing with.

    The course is designed for all professional with background and experience in geology and petrophysics, whose role of job require is using unconventional reservoirs petrophysical, concepts. They include petrophysicists, geologists, reservoir engineers, other E&P professionals.
