This article is about main results of geological prospecting and petroleum exploration which was conducted in independence years of RoK in boundary regions of Caspian sea: Azerbaijan, Turkmenia, Iran, Russia and Kazakhstan. Considered current problems of development and exploration of offshore fields. Stage by stage exploring is a basis of effectiveness of geological exploration. Close collaboration of subsurface users and research institutes will improve petroleum reserves development technologies. Kashagan is a high amplitude rift related positive structure in presalt formation of North Caspian Sea. It was discovered by prospecting seismic operations by Soviet Union geoscientists in the period from 1988 to 1991. This research was confirmed by marine seismic researches by foreign geoscientist companies. This research was ordered by government of Kazakhstan. Kashagan is supergiant oil-gas field of Kazakhstan. It is located in the North of Caspian Sea. It is one of the giant fields in the world which was discovered for last 40 years, and it is the biggest offshore oil field.
