Well logs
• Why is it important to understand the hole quality when reviewing well logs?• What about the density/neutron tool causes it to be affected by poor hole conditions? Think about the configuration of the actual physical tool

Name the three main (there are more than 3 but list whatever you feel is most important) components that make a good landing zone.Elaborate on each and explain why they matter when identifying a horizontal well target.
• What is Tmax?• Which peak in a pyrolysis (RockEval or Hawk) is interpreted to obtain Tmax?• How is Tmax relevant? Why does it matter that weunderstand this in organic shales?
Name three different interface types commonly found in unconventional plays and how they may relate to their geologic environments.
What are the two main extraction techniques used to remove fluids for core analysis and how do they differ? These are the two main methods in the MRP workflow developed by the WDVG lab.
What logs can be used to obtain a more representative insitu water saturation in unconventionals? What feature of the rock could affect the resistivity response that may skew the saturation interpretation? Remember the different types of resistivity tools, which orientation they measure and how the rock fabric can affect the results.
