Application of microgravimetric survey in Samawa salt deposit, Iraq

Abstract

The applicability of microgravimetric surveys for determining the thickness and shape of a salt deposit has been explored by carrying out field measurements. The survey includes five profiles crossing a Samawa salt deposit that attains a maximum thickness of about 8.5 m. The results indicate that the method can be applied successfully if a few boreholes are available as control points to define the local regional field. A simple sheet formula with a fixed density value was used in determining the bed thickness and the general shape of the deposit. The thicknesses calculated in this way agree well with the available borehole information.
