Controlled-Source Audio Magnetotelluric (CSAMT) Survey of Steamflood in Subsurface Tar Sands

摘要

A steamflood experiment, designated TS-1S, was conducted by US DOE Laramie Energy Technology Center in the Northwest Asphalt Ridge Tar Sand. The later stages of this experiment were mapped at depth using the controlled-source audio magnetotelluric (CSAMT) technique to assist in determining the location of the steam front. Normalized maps were produced which are consistent with the production data, temperature data from monitoring wells, and post-test coring data. The results indicate that the CSAMT technique shows promise for monitoring thermal-front locations. 9 figures, 2 tables. (ERA citation 08:029069)
