OIL AND GAS PROSPECTS OF ENISEI-KHATANGSKY REGIONAL TROUGH
From positions of present state of exploration, geological structure of Enisei-Khatangsky regional trough is characterized. Regional seismogeological model of clinoform complex is presented. There were outlined 18 clinoforms of northern dip with echelon-like replacement of each other and one oncoming - Taimyrskaya. Clinoforms are integrated in five megaclinoforms which with great probability appear to be separate reservoirs. Oil and gas potential prospects of the first priority exploration object - Cretaceous clinoform complex (Nizhnekhetsky and Sukhodudinsky reservoirs) with area exceeding 74000 km2 are substantiated. It is given prognosis of high prospective, prospective and low prospective zones of oil and gas accumulation. Total area of prospective lands attains 35000 km2 with shelf - 13000 km2, basin - more than 22000 km2. Resources of clinoform complex were evaluated by D1 category (resources of HC of unassigned subsurface fund): oil - 1684,1 (recoverable - 336,8) million tons, gas - 3800,0 billion m3, condensate - 380,0 (recoverable - 190,0) million tons.
