Example

Screenshots below were obtained for the following configuration:

• Vertical well H=2500 m, ID=0.199 m
• Casing H=700 m, ID=0.199 m, OD=0.219 m
• Drill string H=2000 m, ID=0.121 m, OD=0.14 m
• Transmitter gap at depth H=1800 m, gap size=0.04 m
• Signal strength 3 Volt, frequency 10 Hz
• Signal form factor 0.5 chosen to approximate real-world source with a sine wave
• Surface antenna L=200 m away from the well
• Drilling fluid Ro=50 Ohm*m, Mu=1.25E-6
• Four rock layers:
  1. Ro=20 Ohm*m, Mu=1.25E-6, H=609 m
  2. Ro=10 Ohm*m, Mu=1.25E-6, H=914 m
  3. Ro=15 Ohm*m, Mu=1.25E-6, H=1828 m
  4. Ro=25 Ohm*m, Mu=1.25E-6
