Exploration Basis
EGS potential of Coso Geothermal Region
A dense grid of magnetotelluric (MT) stations plus contiguous bipole array profiling centered over the east flank of the Coso geothermal system is being acquired. Acquiring good quality MT data in producing geothermal systems is a challenge due to production related electromagnetic (EM) noise and, in the case of Coso, due to proximity of a regional DC intertie power transmission line. To achieve good results, a remote reference completely outside the influence of the dominant source of EM noise must be established. The MT times series has been successfully unwrapped and applied using results from the permanent observatory at Parkfield, CA, and these permanent observations appear adequate to suppress the interference of the artificial EM noise from the DC intertie.
