Wednesday, August 26th - Session Overview

Carbonates & Unconventionals
As shale, tight sand and liquid rich plays, like the Duvernay & Eagle Ford continue to attract investment and deliver results, we will see two presentations dig into the specifics. The similarities and differences of the Eagle Ford and Duvernay will be examined.

We will see presentations discussing some of the classic carbonate reservoirs and oldest formations. The relationship between structure, facies, reservoir character and diagenesis will be examined of the Mission Canyon Formation. We will also look at how ichnology and sedimentary textures has led to the indication of porosity development, while identifying a glimpse of flooding of the North American continent at Cambrian time.

Eagle Ford and Duvernay – Are they lookalikes? I’ll let you be the judge of that…
Carolyn Currie | Core Laboratories Canada

Presentation Overview
We find 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.
Alexander K Pollard | Saskatchewan Geological Survey

Presentation Overview

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.

Upper Cambrian-Lower Ordovician Carbonates from the top of the Deadwood Formation in the Williston Basin of Southeast Saskatchewan.

Presentation Overview

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.
