• Questions for Well A 1-34
• How deep was surface casing set? What size casing
  did they use? What
• size drill bit was used to TD?
• What is the reference elevation datum for the
  well logs?
• What matrix density was used to calibrate the
  density log? What was the
• logging speed (feet per minute) and how long did
  it take to log the porosity?
• 4. What is the lithology in all 3 zones?
• Color sandstone yellow, carbonates blue
• Define intervals having positive separation on
  the microlog in the upper zone.
• How many GR API units define the shale base-line
  through the Middle and
• Lower zones?
