Land CSEM Simulations and Experimental Test Using Metallic Casing in a Geothermal Exploration Context: Vallès Basin (NE Spain) Case Study

Abstract: Controlled-source electromagnetic (CSEM) measurements are complementary data for magnetotelluric (MT) characterization, although its methodology on land is not sufficiently developed and tested as in marine environments. Acquiring expertise in CSEM is crucial for surveys in places where MT cannot be performed due to high-levels of cultural noise. To acquire that expertise, we perform CSEM experiments in the Vallès fault (Northeast (NE), Spain) where MT results have been satisfactory and allow us to verify the … Show more

“…Because we employ PETSc solver implementations, no particular work was undertaken to reduce run-time, as this is an completely different goal. However, these numerical results indicate a remarkable benefit when parallel executions are employed (similar conclusions to that described in [31,32]).…”

“…We point out that the significant differences in the electric field components imply that the vertical EM field is more susceptible to the perturbations of the resistivity model and is more informative than the in-line EM field for laterally heterogeneous targets. Then, this feature could be employed to get better signal-to-noise trade-offs on stations near to the vicinity of the resistivity unit [32]. Nonetheless, we acknowledge that this EM field pattern is reduced and only effective close to the reservoir location (x = 730.5 km to x = 735 km).…”
