UNCONVENTIONAL RESERVOIRS PETROPHYSICAL MODELING

ABOUT THE COURSE


This course provides a technical overview of the petrophysical studies, formation evaluation, completion and developmental aspects of unconventional reservoirs, and scoping the light especially on (Gas Shale). Especial emphasis on what is unique compared to conventional oil and gas. The course also reviews the status and characteristics of various plays and the factors that control reserves and productivity. Participants will gain practical insights on the techniques and technology applied in evaluating and developing the unconventional reservoirs.

WHO SHOULD ATTEND?


  •   Geologists
