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.
Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).
