Recent interest in unconventional gas resources has attracted several oil and gas explorers to sedimentary basins in Southern Quebec. The main target of this interest is the Middle Ordovician Utica Shale. Current knowledge of the area’s geology led industry to subdivide the Shale-gas potential into different plays. JUNEX subdivided it into five different plays:
most operations have been performed in the medium-depth thermogenic
Shale gas play (1000-2000 meters), located in the central part of the
Saint Lawrence Lowlands. With OGIP estimates ranging from 25 to 350 Bcf
per section, the play is definitely considered to be promising. However,
other plays are also attractive and, over the past few years, JUNEX has
worked intensively on the development of these new areas of
exploration. They all have different potentials but also different
economics and issues. Based on the exploration work realized by JUNEX
over the past five years in Southern Quebec, the characteristics of the
five plays, from a geological, geochemical, structural, and geophysical
perspective, are reviewed. The five plays are described, based on the
data available regarding the basin geology, shale mineralogy,
organic-matter type, gas geochemistry, structural style, and
infrastructure access. As a result, a new Shale gas potential map will
be available for the Southern Quebec sedimentary basins.
This e-symposium is ideal for geologists, geophysicists, engineers and other geoscientists who are involved in gas shale exploration and production.
Marcil is Exploration Manager for Junex Inc. As such, he plans and
manages the exploration work undertaken by the company. Junex is an oil
and gas key player in Eastern Canada with exploration rights covering
about 6.7 million acres. He is responsible for assessing the hydrocarbon
potential of the company’s license. Mr. Marcil has a BA in Geological
Engineering and a MSc. in Structural Geology a Université Laval. He has
worked in the field of exploration since 1997. During his career he has
participated in projects in several regions of Quebec and Western
Canada. He has been with Junex since 2001. He is an active member of the
Ordre des Ingénieurs du Québec (since 1999) and the American
Association of Petroleum Geologist (since 2004). His main professional
interests include structural geology and geochemistry.
Since its founding in 1917, the American Association of Petroleum Geologists has been a pillar of the worldwide scientific community. The original purpose of AAPG, to foster scientific research, to advance the science of geology, to promote technology, and to inspire high professional conduct, still guides the Association today.
AAPG provides publications, conferences, and educational opportunities to geoscientists and disseminates the most current geological information available to the general public.
As the world's premier professional association for explorationists, AAPG is about the science of petroleum geology.
It's also about the people.
AAPG's membership is made up of more than 40,000 members in 129 countries in the upstream energy industry who collaborate – and compete – to provide the means for humankind to thrive.
AAPG provides the network of communications that allow those professionals to succeed.
We invite you to see who we are, what we are about and to contact us for membership information or details about the many services we provide.
