Abstract
In 2016 additional 65 TEM/MT data pairs were collected in the Hengill geothermal area in order to explore the geothermal field and its potential in a greater detail. Using the new and existing data, three new 3D models were obtained. The models cover the following areas; 1) The Meitlar area, a greenfield located SW of the main production area; 2) The Hverahlíð area where production has recently started and 3) the Skarðsmýrarfjall area, east of the center of current production. The models were all created using the WS3DINV code, where static-shift corrected MT data were inverted for. In all cases the data were rotated into the dominant strike direction (N30°E) and the off-diagonal elements of the impedance tensor were used. The effect of nearby oceans was taken into account and several initial models were used.
