Oil and Gas Content of the Productive Series and Analysis of Geological-Prospecting Efficiency
摘要
The South Caspian Basin’s main oil and gas-bearing complex (SCB) is the Productive-Red Series of the Lower Pliocene age. This complex is characterized by a higher specific density of the explored (proved) reserves and prospective and expected oil and gas resources. Within the SCB, 531 uplifts have been estimated, including 274 at sea and 257 – on land. Of those, 206 (86 at sea and 120 – on land) have been prospected by drilling. The currently estimated exploration and efficiency coefficients by sea are 0.314 and 0.477, respectively. By land, those are 0.467 and 0.600, 0.388 and 0.548 all over the basin. The current existing oil and gas zonation scheme of the SCB region is given.
