Electromagnetic Surveying Flash Cards
Cards in this deck (7)
- 1How does Electromagnetism work?if you have a coil and you put a current through it, you will generate a dipole field.
This is generating a known field. - 2What is Electromagnetic Surveying?Electromagnetic Surveying Methods make use of the response of the ground to the propagating of electromagnetic fields.
- 3What is the difference between magnetic surveying and electromagnetic surveying?The Earths Magnetic field is pretty constant. Biggest advantage is that you don’t need to have ground contact, which means it can be attached to an aircraft and done fairly quickly over large areas.
- 4Do you need GROUND CONTACT to do a Electromagnetic Survey?Nope! :)
- 5Why would you do electromagnetic surveying at sea?To find the non-conductors as oil and gas aren't good conductors.
- 6Why is Electromagnetic Surveying so popular?No ground contact
Fast
May be airborne
Can operate in difficult physical conditions – even downhole
Good coverage at a low cost - 7What are the Applications of Electromagnetism?Geology
Landfill
Groundwater
Engineering geology
UXB
Utilities
Archaeology
Geothermal energy
Borehole geophysics
