Stone's Notes

This conversation with Hilary Corlett is about understanding dolomite diagenesis by analyzing elements and isotopes in age equivalent calcite and dolomite filled burrows. It is based on Hilary Corlett and Brian Jones's  technical article titled “Petrographic and Geochemical Contrasts Between Calcite and Dolomite Filled Burrows in the Middle Devonian Lonely Bay Formation, Northwest Territories, Canada: Implications for Dolomite Formation in Paleozoic Burrows”.  

What is the importance of bioturbation in dolomitization?  What geochemical differences are seen between calcite fills and dolomite fills?  What does a diagenetic halo look like?  Which borrow fill is more proximal?  Which burrow type represents anoxic deposition?

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 Dave Hills is about the geology of the first large-scale CO2 enhanced oil recovery project kicking off in the Leduc Clive Field in Central Alberta, based on Dave Hill's  technical article titled “CO2 Enhanced Oil Recovery in Alberta”.  

Why is the Leduc formation an ideal reservoir for carbon dioxide injection?   What kind of geologic features impact the geomodelling and simulation of the fluid flow?  How much oil can be recovered from the historic reservoir with tertiary recovery?  Has this been done before?  What is the ATCL?

This conversation with Murray Gingras is about how the first animals survived in low oxygen environments, based on Murray Gingras, James W. Hagadorn, Adolf Seilacher, Stefan V. Lalonde, Ernesto Pecoits, Daniel Petrash, and Kurt O. Konhauser's  scientific article titled “Possible evolution of mobile animals in association with microbial mats”.  

What was the world like 2-3 Billion years ago during the Edicarian time period?  What are some of the first trace fossils that we see on Earth?  How did animals survive in low oxygen environments?  How does the oxygen signature change around microbial mats?

This conversation with Isabelle Zelazny is about Montney outcrops, based on Isabelle Zelazny, Aimee Gegolick, John-Paul Zonneveld, Tiffany Player, and Thomas Moslow’s  scientific article titled “Sedimentology, stratigraphy, and geochemistry of Sulphur Mountain (Montney equivalent) Formation outcrop in south central Rocky Mountains, Alberta, Canada”.  

What is the big picture of the Montney geology in equivalent outcrops?  What tests are most important to understand the rock?  How does the geochemistry change within the formation?  What different lithofacies are present?

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 Don Hladiuk is about the planetary geology focusing on meteoroids, meteors, and meteorites.  

How do you recognize a space rock from an Earth rock?  Where do meteorites come from?  How are meteorites brought back from space?  What big events happened in the past?  What do you do if you see a fireball?

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.
