The Epsilon field, is located at the centre of Prinos oil basin (N. Aegean, Greece), 11 km NW of the island of Thassos and 4 km NW of the Prinos field, the first productive oil field in the Aegean Sea. The taphrogenetic basin of Prinos has been widely studied, due to its hydrocarbon reservoirs. Extensive geophysical survey, started at early 1970 ‘s, led to a number of drilling jobs, which confirmed the existence of hydrocarbons in the area. The combined geological information, derived from the analysis of lithological, stratigraphic and geochemical data of the basin, suggested a structural and depositional model, strongly related to the Miocene tectonics and sedimentation. The new geophysical and drilling data from Epsilon oil field, are correlated to that already known, completing the model of the basin. Pay zone is found to be below an evaporitic sequence, consisting predominantly of salt, with anhydrite, clay and sandstone intercalations. These upper Miocene aged evaporites extend, varying in thickness, throughout Prinos basin. Reservoir consists mainly of sandstone with intercalations of claystone and trace of siltstone. The geology of the structure and the initial productivity, were positive for further drilling operations in Epsilon field.

The active development of the Russian Arctic in the last 10 years requires relevant data on the bearing capacity of rocks on the Arctic shelf of the Russian Federation. To assess the bearing capacity of soils, knowledge of the distribution and state of permafrost on the Arctic shelf is needed. The article discusses the rationale and possibilities of the proposed integrated geocryological and geophysical analysis. The technique of researches includes realization of sea electroprospecting works, drilling on the shelf, thermometric observations in the drilled wells, bench tests of soils, modeling of electromagnetic and thermal fields on the shelf. It is shown that the most informative geophysical method for studying of permafrost on the shelf is electromagnetic sounding by the TEM method. The most informative geophysical method for studying of permafrost in the transit zone “land-shelf” represents the frequency electromagnetic (FS) sounding. In the article there are examples of standard interpretation of geophysical data and inversion of geophysical data in the mode of the fixed model specific electrical resistivity. With the example of the yamal shelf it is shown that standard interpretation doesn’t allow to receive the unambiguous solution of geocryologic tasks on the shelf. Specific electric results of determination of electric properties of soils in laboratory are necessary in case of inversion of geophysical data in the mode of thickly stratified models and the fixed model. An important component of the offered complex is boring and thermometric research which provide validation of results of geophysical inversion. Measurement of temperatures of soils in the stood wells is especially important in the conditions of the Arctic shelf. Calculations for thermal models complete a complex of researches. The collateral analysis of geoelectric and thermal models allows to estimate depths to a sole of permafrost and also capacities of gaseous-hydrate thicknesses. The use of the developed research complex on the Pechora, Karsky, Laptev and Chukchi seas shelves provided new insights into the distribution, continuity and condition of permafrost and the development of gas hydrates on the shelf of the Russian Arctic seas.
