It is becoming increasingly obvious that shale plays are nonhomogeneous structures and all vertical sections within a zone are not created equal. A recent article about unconventional plays in the March 2012 issue of the AAPG Explorer stated, “A reservoir is a 3-dimensional section of earth” and “People are integrating 3-D with as much borehole data that are available at the start of the workflow and throughout the process”.
This e-symposium will focus on how surface geochemical surveys and Downhole Geochemical Imaging technologies can be utilized jointly to directly characterize the composition of hydrocarbons vertically through the prospect section. This methodology has the unique ability to look at a broad compound range from C2 to C20, which is significantly more expansive than the limited traditional ranges of C1-C5 or C1-C10 of most well gas logging techniques. The result is a broad characterization of petroleum phase contained in the stratigraphic intervals down the well.
This data may be used to:
Correlate with electronic and nuclear logging results to better define test intervals of interest
Identify preferred completion zones and petroleum phase (gas, condensate, oil)
Reduce testing/completion costs and time
Evaluate seal rock integrity
Better understand petroleum migration patterns and petroleum phase differences between source, migration, and reservoir rocks
Potentially understand vertical compartmentalization
Case studies will illustrate that Gore’s horizontal approach of Amplified Geochemical Imaging technology and Gore’s vertical approach of Downhole Geochemical Imaging provides a 3-Dimensional approach to evaluating resource plays.
Who Should Attend
Persons interested in learning how surface geochemical data and downhole imaging technology can work together to give a better understanding of hydrocarbon mapping.

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.
