Introduction to Petrophysics - Including Traditional and Reservoir Petrophysics

Introduction to Petrophysics covers fundamental petrophysical relations, with a primary focus on understanding water saturation, fluid contacts and free water level.  Participants learn formation evaluation based on pore-geometry and petrophysical rock types.

Additional topics include fundamentals of core analysis, wireline log and open-hole interpretation. Applied work sessions (Excel) and participant presentations (PowerPoint) are key cornerstones that help participants gain confidence in using these methods. Several case studies are used to show the importance of integration between geology, geophysics petrophysics and reservoir engineering. 

Petrophysical rock types are introduced in the 3 day version, capillary pressure and saturation height models are introduced in the 4 day version and flow units are introduced in the 5 day version.

This course can be offered as a 3, 4 or 5 day option.  The course outline of proposed topiscs, provides additional details. 

Typically, over 30 percent of the course is “learn by doing, which includes workshops, participant presentations and group discussions”.
