The article is devoted to the results of hydrocarbon prospects estimating on the Pechora sea shelf within the Gazprom Neft license areas. The area was clustered according to its geological and geophysical features. More than a hundred prospective objects are defined in six oil and gas complexes. Overall estimated hydrocarbon potential is more than 2,525 billion tons. The assessment is based on integration of regional 2D seismic data, new 3D seismic data from the three license areas, as well as core and outcrops data from adjacent areas. Based on sequence stratigraphic analysis, the reservoir properties and other parameters of the prospective objects were clarified. The promising objects are rated on the basis of key geological and geophysical indicators. Moreover the location for appraisal drilling for subsequent exploration is proposed. In addition to determining oil and gas content of Triassic, Permian and Carboniferous reservoirs, it is spoken in details about prospects of deep complexes. These complexes are reef traps of the Upper Franian, terrigenous reservoirs of the Middle Devonian and Prague stage, hypergene carbonate reservoirs of the Ovinparmian horizon (Lower Devonian) and Ordovician-Silurian carbonate rocks. Aiming to discovering giant fields on the Arctic shelf one of the technological challenges has been identified – drilling in difficult climatic conditions to prospective horizons at depths of more than 4.5-5.5 km. The proposed exploration and R&D program allows to determine the optimal well location and to solve non-standard technological challenges to achieve this ambitious goal.
