and Duvernay – Are they lookalikes? I’ll let you be the judge of that…

ourselves consumed with comparing data, especially as of late with the
emergence of ‘big data’ and artificial intelligence software, whether that be
on a global scale or field scale or micro thin-section/SEM scale. This
presentation does exactly that – looking at two world class shale plays -
taking an in depth look at what makes them tick (or not tick?!?!?). Can you
compare the Eagle Ford and Duvernay Formation? What can we learn about these
similarities in terms of completion techniques? What can we learn about the
differences? Or is this simply in the eye of the beholder and they are
completely different and unrelatable? We shall find out…
About the Speaker
Carolyn Currie’s primary position as senior geologist and project lead has included work on various unconventional plays in North America and globally including Duvernay, Montney, Wilrich, Eagle Ford, Marcellus, Midland Basin and Deep-Water Mozambique. She currently serves as the Manager of Geology and Integrated Studies, leading such projects as the Duvernay, Montney and Wilrich/Spirit River consortia studies in the Canadian office. Throughout her time at Core Laboratories and previous projects (including her master’s project), she had logged, described, interpreted and integrated 500+ cores ranging from unconventional shales, tight sand formations, deep water sandstones, heavy oil/oil sand cores.

Facies architecture, diagenesis and reservoir character of the Alida ad Frobisher Beds of the Mission Canyon Formation from the Gainsborough Pools, Southeastern Saskatchewan.
K Pollard | Saskatchewan
This contribution to the 2020 CSPG Core Conference comprises a core examination study from the Gainsborough Pools in SE Saskatchewan. This presentation will detail the relationship between structure, facies, reservoir character and diagenesis of the Mission Canyon formation. A definitive relationship between structure, facies and reservoir quality cannot be discerned accurately through petrophysical log interpretation. To accurately characterize emerging plays and target economically viable reservoirs, a comprehensive core examination study is necessary.
About the Speaker
Alexander (Alec) Pollard is a carbonate sedimentologist with several years of industry and academic research based on reservoir characterization of carbonate rocks. Mr. Pollard has a B.Sc. (Hons) in Geology from Lake Superior State University (Michigan, USA) and a MSc. in Geology (carbonate sedimentology focus) from Queen’s University (Ontario, Canada). Mr. Pollard has continued to pursue carbonate systems research projects while developing his industry experience and technical expertise. Mr. Pollard has published and presented a diverse range of carbonate research on rocks of different ages and locations. Mr. Pollard’s research interests include the analysis of complex carbonate sedimentology, such as Paleozoic carbonates in Williston Basin reservoirs, and interpreting facies of Miocene carbonate reservoir rocks in the Columbus Basin, Trinidad. Mr. Pollard is also passionate understanding the stresses on modern marine systems and investigating stabilizing solutions. Alec was born and raised in Trinidad and Tobago, and is currently based in Western Canada.

A total of 26 metres of low energy upper shoreface limestone was recovered from the top of the Upper Cambrian-Lower Ordovician Deadwood Formation in the deepest portion of the Williston Basin in southeast Saskatchewan. The carbonates are not dolomitized and were deposited in an open marine muddy upper shoreface to tidal flat environment and represent sedimentation on the equatorial stable American Carbonate Platform. One wonders how fast these muds accumulated considering the absence of allochems in the accumulation. The absence of exposure surfaces suggests the section was deposited on a very stable platform with sedimentation able to keep up with sea level rise. Ichnology was important in interpreting environment of deposition.
About the Speaker
John Lake received a B.Sc. (Honours) in Earth Sciences from the University of Waterloo in 1973 and an M.Sc. in Earth and Planetary Sciences from McGill University in 1977. His M.Sc. thesis was on Upper Ordovician Carbonate Mud Mounds on Anticosti Island under Dr. Eric Mountjoy. John worked for Mobil Oil Canada in Calgary from 1979-1989 and Saskoil/Wascana in Regina and Swift Current from 1990-1995. Since then he has been consulting to the Oil Industry in the Williston Basin.
