Abstract

A broad range of exploration methods were applied to the search for shallow gas accumulations in the Thrace Basin, west of Istanbul. The methods ranged from satellite imagery, geomorphology, surface geology, through electrical to seismic surveying. At each stage areas were relinquished and efforts concentrated on those more prospective. Resistivity surveying was used to localize the prospective target zones, with Electromagnetic Imaging and 2D seismic applied to determine the target depth and geometry.
