Abstract
The materials of additional testing of mobile direct-prospecting methods on the Alaska, Peru offshore are presented. Experimental studies have been carried out in order to demonstrate the operability, efficiency and potential capabilities of the developed methods during hydrocarbons (HC) accumulations searching. The studies performed on oil and gas drilling sites confirmed the feasibility of additional works conducting with using direct-prospecting methods when choosing sites for their laying. Within deep channels (volcanoes), filled with sedimentary rocks of 1–6 groups, signals (responses) are almost always recorded at the resonant frequencies of hydrocarbons (HC) and, in many cases, amber. Signals at the frequencies of oil, condensate and gas are also recorded quite often in volcanoes, filled with limestone. In volcanic complexes filled with sedimentary rocks of 8–10 groups (dolomites, marls, siliceous rocks), responses at frequencies of oil, condensate, and gas have never been recorded. In many areas of the survey, in the contours of responses from the HC recording, the existence of a 57 km boundary was confirmed, in the region of which the oil, condensate, gas and amber are synthesized from hydrogen and carbon migrating from below.
