PSA webinar series is a GeoSophix' initiative aiming for a step improvement of PSA practice worldwide. It has been re-examining some of the fundamental PSA workflows, challenging rooted paradigms and presenting state-of-the-art ideas from leading PSA experts. Each webinar attracts 100-150 registrations globally. Of interest to any Exploration Geologist, Geochemist and Basin modeler - junior or experienced.

The webinar is supported by several colleagues around the globe. With its PSA YouTube channel, it complements technical discussions at the  PSA group on LinkedIn and more in-depth technical contributions at the Petroleum System Blog.

PSA webinar 7

Hartmut Jaeger - Optical Kerogen Analysis - Old wine in new skins or a step forward to bring source rock analysis to a new level?

Kerogen is a mix of different types of organic particles - each with different kinetic behavior and production potential. Traditional bulk chemical/RockEval analyses do not differentiate among them. The consequences are significant and eye opening...

Hartmut Jaeger - Vitrinite reflectance on trial – is there anything better in organic maturation analysis?

Vitrinite is a key maturation indicator. How reliable is it? 

PSA webinar 5

Robert Lander - Model the Rock! Using Diagenesis Simulation for Rock Property Prediction

This time, we focused on the "Reservoir" element of a petroleum system. What controls reservoir quality, how depositional characteristics and burial history affect rock properties, how can rock properties be simulated? 

PSA webinar 4

Alan Burnham - Evolution of vitrinite reflectance models

Everyone uses it, a few understand it. A fundamental calibration of thermal basin models but... should it be? How reliable are vitrinite reflectance models? How do they work? Have we hit irreducible uncertainty limits? Alan Burnham explains everything you should know about vitrinite reflectance models before you apply them.

Zhyiong He - All models are wrong, some are useful: Best practices in petroleum system analysis

Basin modeling has been fully accepted and used throughout the oil industry, yet, the dry hole rate remains the same (high). Why? We have been spending a disproportionate effort on things that cannot be validated. Let's focus on parameters that do matter!

PSA webinar 2

Alain Yves Huc - Source rocks: Factors controlling the formation and distribution of organic-rich sediments; Facts and modelling

How often do geologists view source rocks as fairly homogeneous layers of organic rich mud that is distributed fairly uniformly within a basin, perhaps with the highest TOC in a depocenter? Alain Huc takes us through the processes of organic matter formation, degradation, deposition, mixing with minerals, burial and preservation. You will never look at source rocks the same way...

Andrew Pepper  - Explaining it better: the Organofacies scheme in modeling petroleum charge from source rocks

The series of Pepper and Corvi papers from the mid 1990's has become a key reference work within the field of petroleum systems analysis. It has been encoded in many basin modeling tools and many geoscientists apply it yet few truly understand it.
