The mapping of enhanced oil recovery (EOR) processes is important to predict process behavior and to be able to exhibit some control of the process for maximizing the stimulation of oil reservoirs. The controlled source audio-frequency magnetotelluric (CSAMT) electromagnetic geophysical technique shows promise for mapping steamfloods and firefloods. Two field trials were conducted, one at a steamflood tar sand oil recovery experiment and one at a fireflood heavy oil recovery process. An initial report of the results was given previously. In this paper, an analysis will be given of the CSAMT results for the two floods along with a comparison with production and post-test results. The result of this work is that the CSAMT technique is a viable technique for mapping these thermal EOR processes. In addition, a discussion of mathematical modeling will be given.
