Re: Regular method for pre-drilling water wells

"Space-saving" methods: 1)TDEM coincident/central loops: 50x50 up to 200m depth, 100x100 up to 350m depth(noise can be problem) 2) radio magnetotelluric with controlled source: receiver's line just 20-50m, up to 120-150m depth (instruments are expensive, You need in setting up of transmitter at 300...

Re: checker-board test

I suppose that method of DOI index calculation will be much more faster for model test.
