Simulated Annealing for CSAMT 1 Dimension Inversion

Abstract

We applied simulated annealing in CSAMT 1 dimension inversion. We demonstrate the simulated annealing flexibility for starting models by allowing the model parameters to vary in a large range. The inversion started from 10 different starting models and has 1000 temperature reductions. Numerical calculation model was a three-layer geoelectric model; the observed data were electric field component. The results show all runs converge to the true parameters. The efficiency of simulated annealing for CSAMT 1D inversion is high.

Study on electromagnetic detection transmitter system

“…Controlled source audio magnetotel-lurics (CSAMT) has been used for exploring metal deposits, groundwater, collapse column, geothermal work, massive sulfide natural gas and petroleum widely [2] . Electrical methods using buried transmitters or receivers have become increasingly important exploration tools as exploration for deep mineral deposits has increased [3] , it is the most effective geophysical exploration techniques.…”
