Until recently territory of the Taimyr peninsula was actually a "white spot" on the maps geological and geophysical studies of Russia. Reason is improperly implemented procedure, which in 1980-1990 conducted a significant volume of seismic CDP-3D, no pre-made regional stage research. The situation is change in 2005, when JSC “Yuzhmorgeologiya” are started to carry out regional complex geophysical surveys on the Taimyr Peninsula. From 2005 to 2014 a number of promising objects for licensing were identified, which led to a sharp increase in interest from subsoil users. During this time JSC "Yuzhmorgeologiya" was worked out more than 3000 lin. km of 2D CMP survey in hard zones of Taimyr peninsula. The work is devoted to researches of influence seismogeological, climatic and lithological conditions area of work quality of the data regional and local materials, and the criteria for the analysis of quality seismic material (due to their absence), and changes in the approach to some technological aspects of exploration.
