Basin Analysis & Sequence Stratigraphy Division
For more information concerning this Division, please contact the Division Chairs, Steve Donaldson at (403) 645-5534, email: Steve.Donaldson@encana.com or Mark Caplan at (403) 532-7701, email:mcaplan@aosc.com.
Division Profile
The Basin Analysis and Sequence Stratigraphy Division was created in 1999 to replace the existing Basin Analysis Division, reflecting the increasing popularity of sequence stratigraphy. The Division's mandate is to provide a CSPG forum for members who are interested in seeing the "wood" when they are looking at the "trees". Most of us deal with small areas in our daily work. Good understanding of the big geologic picture in which our areas are located will facilitate better geological interpretations and predictions, which will translate into higher drilling success rates.
The aim of the Basin Analysis and Sequence Stratigraphy Division is to be innovative, inspiring and practical. We will try to introduce new concepts and methodologies of basin analysis and sequence stratigraphy to our group. We would also like to share inspiring interpretations of historical Canadian data. In particular, we encourage speakers to offer learnings that we can take home and apply in our daily work. The Division is also interested in running field trips or joint talks with other Divisions in the future.
Our meeting schedule is to have at least one informal brown-bag talk every month, except during the summer. Talks normally start at 12 noon and finish before 1 p.m. Each talk consists of a 40 minute technical presentation followed by a 10 minute question period. Currently, our meetings are held at the EnCana Amphitheatre, 2nd Floor, east end of the Calgary Tower Complex, 1st Street and 9th Avenue SE, Calgary, Alberta.
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.
The Division's new co-chairs would like to express our gratitude to Greg Hu for his hard work in developing and running the Division. If you are interested in joining the Division's mailing list and learning more about it, or if you would like to suggest a technical topic or present a talk to the Division, please contact us.

Abstract
Hydrocarbon exploitation processes cannot be economically assessed from a stand-alone point of view; it is imperative to evaluate their viability by considering different stages in the hydrocarbon recovery process chain, from the reservoir to the upgrading facilities. This is possible today. Petroleum Engineers can model the entire production cycle, from the reservoir through the production network to the surface facilities, all of these integrated with economic analysis.
This case study presents modeling a Canadian tight gas field including a simplified reservoir model integrated to a fully developed surface network, demonstrating a simplified but realistic model is able to perform a good history match. This model is used to test "what-if" scenarios without risking the actual operation of the production field. Furthermore, the model is also able to forecast the new production based on the application of the operating parameters determined to enhance and optimize their production.
Biography
Mahyar (Matt) Mohajer is a Production Engineering consultant with Schlumberger Information Solutions (SIS). Mr. Mohajer earned a B.Sc. in Chemical Engineering from Sharif University of Technology in Tehran, Iran and an M. Sc. in Chemical Engineering from the University of Calgary. Prior to his graduate studies, he worked as a Process Engineer for IRITEC (Iran International Engineering Company) in Tehran. He participated in modeling and designing amine-based gas sweetening and sour water striper units. In 2006, he joined SIS in Calgary and he is currently involved in providing support and consultancy services using SIS' production portfolio.
Unlocking CBM and Shale Gas Reservoirs

Abstract
This presentation is to demonstrate how to use the non-traditional data collected by an asset team to understand their unconventional reservoir, here a shale gas play. It focuses on the treatment of fractures and faults, paramount to the flow behavior of the reservoir. It also shows how useful the mineralogical information can be to distinguish the variation of production potential.
Last but not least, flow simulator enables to take into account the adsorbed gas released to have a more reliable prediction of the reservoir evolution through time and so the recovery, overall and through time. For instance, as with sandstone and carbonate rocks, shales vary in composition and properties, which affects the recovery potential of the reservoir. Three dimensional modeling provides a tool to study this variability which affects recovery; it is important to understand how the amount of adsorbed gas changes. Study of this and other unconventional properties is required to unlock the secrets of shale gas or coal bed methane developments.
The workflow presented includes:
- Integration of non-traditional data and sub-seismic fractures information,
- Double/triple porosity (fracture, matrix and adsorbed gas) in Petrel Reservoir Engineering Core, and
- Single well simulations used to predict full field recovery.
Benefits: A full three-dimensional geological model is needed to study a shale gas play. Non-traditional data can be incorporated to help understand the recovery variability. Single-well simulation models, easier and faster to model and run, can be used to validate against observed production data and to predict recovery variations.
Biography
Isabelle Pelletier Tardy has spent 15 years in the petroleum industry as a geoscientist. She obtained her Ph.D. in Geochemistry/Hydrogeology, at the French Petroleum Institute (IFP) in 1997, in collaboration with Total and Elf, where she studied the clay diagenesis of Dunbar's sandstone, North Sea.
Tardy started her geological career as a geostatistic and stochastic modeling expert with Roxar (1998-2000), and then in 2000 with Schlumberger, first in its English Cambridge Research Center, and since 2004 in Houston. In 2005, she joined SIS Business Development. She has worked on simulation and production portfolios, where she has implemented solutions like optimizing drilling plans where the geology is uncertain, water flood management, unlocking the potential of CBM and shale gas plays, heavy oil, and CO2 sequestration.
