In this authors discuss the results of exploration work performed in 2010-2012 on the territory of Maloklyuchevoye oil field on the basis of geologic-geophysical studies. Challenges associated with additional exploration were solved by 3D seismic survey, prospect drilling and well testing techniques in the previously drilled wells. Geological structure of the Maloklyuchevoye field and its connection zone with the Severo-Potochnoe field was clarified by seismic survey of MOGT 3D (the territory is 270 km2). Oil reserves were changed almost in all paying zones (except Ach2 formation) as a result of the drilling of exploration well 4P and operational drilling data. Test of BV10 formation in the well 4P confirmed its commercial oil content. As a result discovery of new oil saturated layers the level of oil-bearing for the Maloklyuchevoye field was increased.
Today this data and conducted comprehensive analysis are used for designing additional exploration work on the neighbor territory, Eguryahsko-Martallerovskaya zone (North Eguryahsky 1, 2 and Martallerovsky license areas).
Thus, a full range of research, including drilling data, well logging data, dynamic, litho-facies and paleogeographic analyzes in order to increase the resource base of operating companies and for further exploration of the territories, involving modeling that allows to predict as the new objects and their facial structure, as the reservoir fluid presence. Repeated well test data can be used for evaluation of production capacity of oilfield objects, to reveal the missed objects, and also significantly reduce the financial cost, which is especially important in the current economic conditions.
