Inverted resistivity models

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2016 along 1,443 line kilometers in the southwestern San Joaquin Valley near Lost Hills, California. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as part of the U.S. Geological Survey California Oil, Gas, and Groundwater program and the California State Water Resources Control Board’s Program of Regional Monitoring of Water Quality in Areas of Oil and Gas Production. Deterministic laterally constrained inversions of the processed airborne electromagnetic data were developed using the AarhusINV code implemented in Aarhus Workbench software. Inversion parameters were selected by running [...]
