Recent years have witnessed a huge effort to characterize unconventional reservoirs. These rocks presented new challenges with micro-porosity and porosity associated with organic material. High resolution images in 2 and 3 dimensions have been achieved with the scanning electron microscope (SEM) and the utilization of ion beam milling (FIB and BIB). Three problems are associated with these efforts; the very small size of the area imaged and the possibility that the processes of sampling and preparation have introduced artifacts, and limited scope of data from SEM alone.
We present solutions to the first problem with methods to capture larger image areas using powerful compression and streaming software. The software used allows images from different techniques to be overlaid on one another. Thus, organic matter can be distinguished from pyrite by comparing thin sections in plane light and in reflected light.  Light microscopy images of any modalities can be overlaid with SEM, elemental EDS images, and even with a spectroscopy image to reveal a fullest data from a sample. 
Larger than usual areas are imaged allowing to analyze samples which are more representative of the reservoir than smaller sized ones. Mineral and maceral characterization is thus enhanced and quantification is now possible on much larger representative samples
To address the second problem of potential introduced artifacts, rigorous workflows have been established to monitor the state of the sample at every step of the imaging process. Images are captured and compared to verify that fractures and porosity are primary and not an artifact of sample handling and process.
 A series of examples from the Western Canadian Basin, Permian Basin and Eagle Ford will show some new workflows towards solving the up-scaling and sampling artifact problems associated with characterization of unconventional reservoirs.
Dr. Bernard Lee was awarded a Ph.D. from the University of Texas in cell biology. After graduation Dr. Lee worked for the Carl Zeiss company as an imaging specialist, solving problems for researchers in the bio-medical and geological fields. In 2006, he founded the company Innova Plex which develops and markets devices for the bio-medical and petroleum industries. He invented and obtained several patents on Virtual Petrography system that allows large microscopically scanned images to be compressed and viewed with standard PCs.   He has also developed automated scanners for thin sections, cores as well as nannofossils. He is recently working on a large scale petrographic analysis and nannofossil classification by employing artificial intelligence.

Jean-Yves Chatellier, PhD in geology from Paris, has 35 years of international experience in the oil industry. He worked around the world for Shell before taking a senior advisor job for the research lab of PDVSA in Venezuela where he led to the discovery of two giant oil fields. Since 2003 in Calgary, he has focused on new play concepts and on shale exploration and development (Utica, Montney, Duvernay, Marcellus, Horn River, Eagle Ford and Permian Basin).

Exploration and development in the Plains portion of the WCSB have focussed traditionally on stratigraphic plays, with emphasis on sedimentological and stratigraphic data and interpretation.  Pursuit of structural plays in the foreland basin has been limited mainly to the Foothills fold-thrust belt immediately to the west. As production from long-exploited stratigraphic plays has matured in the foreland basin, new successes in conventional and unconventional reservoirs have become increasingly dependent on understanding the nature and distribution of sometimes subtle structural elements in the foreland basin.

Several unconventional and conventional play case studies highlight the value of understanding structural influence in new foreland basin play exploration and development. Example types include:

  •     Identifying subtle structural control on intersecting depositional facies belts, diagenetic pathways and potential trapping trends in Mississippian middle Banff Fm. helped high-grade prospective areas and make a significant discovery. Success involved a combination of reactivated basement structural trends, and Mississippian syn-depositional and Cretaceous post-depositional extensional faults.
  •     Recognizing syn-depositional extensional fault control of local paleodrainages and reservoir/ seal distribution in the Lower Cretaceous Mannville Gp. lead to local exploration success and useful regional application.
  •      Emerging awareness of compressional reactivation of earlier extensional faults in the basin offers opportunities both for conventional trapping and locally enhanced fracturing in unconventional plays.
  •     Highlighting published relationships between basement-rooted faults and heterogeneities in basin-centred gas production in Cretaceous intervals in the USA serves as analogy for considering similar relationships in the WCSB.

Synthesis of structural influences in the WCSB includes preliminary discussion of geographic distribution of different types of structural elements in the basin.


Marian Warren completed a PhD at Queen’s University, Canada. She subsequently worked at EnCana Corporation in Calgary for 11 years in roles as geologist, seismic interpreter and structural specialist for both domestic and international projects. As a result of successful WCSB projects at EnCana, she was a co-recipient of the CSPG Medal of Merit, winner of the AAPG Matson Award and served as an AAPG Distinguished Lecturer.


Marian became an independent consultant in 2008, with focus on exploration projects worldwide in structurally complex settings, and on developing and presenting industry training courses and field trips. She was also an Associate of Rock Deformation Research in the UK and US from 2009-2014.

Division Profile

Our meeting schedule is to have at least one informal brown-bag talk every month, except during the summer. Talks normally start at 12:00 noon and finish before 1:00 p.m. Each talk consists of a 40 minute technical presentation followed by a 10 minute question period. 

Involvement of our CSPG members is the key to the success of the Division. Individuals are encouraged to take part in all activities. Service companies are also encouraged to attend Division meetings and be involved in all Division activities. Basin Analysis and Sequence Stratigraphy Technical Division Talks are free to CSPG members. Please bring your lunch. For further information about the division, joining our mailing list, a list of upcoming talks, or if you wish to present a talk or lead a field trip, please contact either Steve Donaldson at (403) 808-8641 or Mark Caplan at (403) 975-7701.
