3. In the figure below, a frequency domain EM survey is flown over two buried conducts (A and B). Two configurations of TX and RX are used. Sketch the primary and secondary magnetic field lines when the TX-RX is above conductor. Sketch on the same figure below TX RX Horizontal co-planar TX_RX B TX RX TX RX I Horizontal co-axial B

1000 9. from the VES curve above, it appears the earth is made of three layers. what is true about their resistivities? assume layers from top to bottom marked as 1, 2, 3. Apparent Resistivity (m) 100 a) Pi>P2>p3 b) Pi>P2<p3 c) P P2<P3 d) None of the options is true 10 1000 10 100 AB/2 Spacing (m) 10. In DC resistivity Current lines and equipotential lines intersect each other at a) 100 degrees b) 30 degrees c) 60 degrees d) 90 degrees
