Summary:
The paper presents and analyzes the results of the of mobile and direct-prospecting methods application on a Burgas prospecting area in Bulgaria. Prospecting studies within area were conducted with using the mobile technology of remote sensing data frequency-resonance processing and interpretation and the ground-based geoelectric methods of forming the short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS). Two local anomalous zones (Western and Eastern) of the “oil” and “gas” type have been detected within the prospecting area. Within the contours of these anomalous zones the deposits of oil and gas in industrial (commercial) volume can be found in the cross-section. Discovered by direct prospecting methods anomalous zones can be considered as projections into the surface of hydrocarbon accumulations contours in the cross-section. This information may be used for an approximate estimate of hydrocarbon resources within the surveyed areas and structures. For the Western anomalous zones approximate estimates of probable resources of oil and gas have been calculated by received data of studies. Given that the prospecting and exploration of commercial oil and gas accumulations on the onshore and the development of discovered resources is significantly cheaper than within offshore, the detected and mapped anomalous zones deserve of a detailed studying by geophysical methods and drilling.
