3-Part Online (Self-paced) Tutorial:

Petrophysics for the Geoscientist 

Come take advantage of an opportunity to learn at your own pace, from the privacy of your own home or office computer! In this series of three (2-hour) online tutorials, GeoMark's Chief Petrophysical Advisor, Dr. Stephanie Perry, shares petrophysical knowledge, workflows, and tips/tricks. Listen in as Dr. Perry shares the basics of Petrophysical wireline tools and log responses and the integration of Geochemical and Engineering data with resulting deliverables. Finally, an overview and knowledge-sharing of Petrophysics relevant to the Delaware and Midland Basins, relating Geoscience to the Petrophysical discipline. Feel free to sign up for a single course ($100 per course), or stay for all three ($250 for all three!). Below, we provide a breakout of each:
