Combined gravity and aeromagnetic surveys of the Khulais basin of western Saudi Arabia

Combined gravity and aeromagnetic geophysical surveys were carried out in the Khulais area of western Saudi Arabia to determine the thickness of the sedimentary cover and the depth to the basement. The results suggested the existence of an extensive sedimentary basin structure (20 × 7 km) with a maximum thickness of 1000 m. Similar depth estimations were reported from electrical sounding results.

This is an example of an integrated application of geophysical methods to provide hydrogeological information with an acceptable balance between accuracy and cost.
