D041 Travel Time to Resistivity Mapping Using the Multi Transient ElectroMagnetic (MTEM) Method D. Wright* (MTEM Ltd) & A. Ziolkowski (MTEM Ltd) SUMMARY The time of the peak of the earth impulse response in multi-transient electromagnetic (MTEM) data can be mapped directly to an apparent half-space resistivity. The vertical resolution of this technique is poor. The gradient of the travel time moveout curve has the potential to yield an apparent interval resistivity. However direct mapping of the gradient suffers from large errors due to small errors in picking the time. These errors can be greatly reduced by applying a polynomial
