This conversation with Jon Noad is about applying geologic lessons from physical 3D mines to 3D geomodelling in subsurface reservoirs, based on Jon Noad's technical article titled “Learning from Mining Applications to Unconventional Reservoirs”.  

What can the oil and gas industry learn from the mining industry?  What geologic features can mines help us understand?  How is krigging in mining models the same as in subsurface geomodels?  These questions will be answered while discussing the Portland Stone mine in the UK, the St. Helena Gold mine in South Africa, and a platinum mine in South Africa.

This conversation with Henry Galvis-Portilla is about comparing and contrasting heterogeneities in the Duvernay and Woodford Formations, based on his scientific article titled "Multi-scale Integration of Mudstone Properties in Interbedded Reservoirs, Insights into Additional Criteria for Evaluating Unconventional Reservoirs: Examples from the Duvernay Formation (Alberta, Canada) and the Woodford Shale (Oklahoma, USA)" by Henry Galvis-Portilla, Daniela Becerra-Rondon, Per K. Pedersen, and Roger M. Slatt.

How are the Duvernay and Woodford similar and different?  What characteristics are typical in the two facies in the interbedded reservoirs?  How do you characterize the degree of interbedding?  If you'd like to understand mudstones further, listen in as Henry Galvis-Portilla shares his research findings.

This conversation with Bruce Hart is about fractures and folds in the Cardium Formation due to underlying Kaskapau faults, based on his study titled "Blind thrusts and fault-related folds in the Upper Cretaceous Alberta Group, deep basin, west-central Alberta" by Bruce Hart, Bogdan Varban, Kurt Marfurt, and Guy Plint.

How were the faults identified in the Kaskapau?  What is the significance of these to the overlaying Cardium formation?  How extensive would you expect the fracture network to be? How is the Kaskapau actually pronounced (copy Bruce not me).  If you'd like to understand a geological model where open fractures and increased permeability are due to underlying faults, listen in as Bruce Hart shares his research findings.

This conversation with Wen Lin is about predicting the delta volume from the trunk river parameters using the fulcrum approach, based on his study titled "Estimation of Source-to-Sink Mass Balance by a Fulcrum Approach Using Channel Paleohydrologic Parameters of the Cretaceous Dunvegan Formation, Canada" by Wen Lin and Janok Bhattacharya.

What is the source to sink concept?  Where is a fulcrum located?  Which formations does this fulcrum method work on?  How does fulcrum analysis compare to the BQART method? If you'd like to understand your exploratory target better, listen in for a new tool you can utilize to determine the scale of your reservoir.

This conversation with Dale Leckie is about the roadside geology you will see as you drive from Banff to Jasper as discussed in his book titled "Rocks, Ridges, and Rivers - Geological Wonders of Banff, Yoho, and Jasper National Parks".

Have you ever been driving through the mountains and wondered where the best spots to stop were located?  And once you stopped to stare at the beautiful scenery, were you curious what it was you were looking at? Perhaps questions such as how did these particular mountains form, how are they connected to the mountains you previously passed, and how did the features such as waterfalls form popped into your mind?  

If you'd like to know the answers to all of these questions, join us for a pretend road trip.  We'll be stopping at Mount Yamnuska, Vermillion Lakes, Moraine Lakes, Burgess Shale, Big Bend, Old Fort Point, Magline Canyon, and Roche Miette.
