The Interaction of Tectonics and the Sedimentary Record; The Miocene of the Sakhalin Shelf

Matthew Brettle, Ian Glenister, Richard Barrett, Sussanne Witte, Graham Tiley

Abstract

Recently an extension of the extensions Daekurinski-Amur deltaics play offshore Sakhalin has proven to produce hydrocarbon. The syn-depositional uplift of island produced local sediment source, the present day drainage pattern on island reflects Miocene-Pliocene uplift and allows for prediction of reservoir presence and amount of sediment. Tectonic elements present in the area are Pacific subduction, back-arc extension, subduction of micro-plates within the Sea of Okhotsk area, Miocene strike-slip, Himalayan extrusion techonics and Pliocene inversion. There stratigraphy of the area includes Eocene-Oligocene fans systems, Early Miocene deltaic systems and late Miocene shelf systems. The Pomyr, Nutov and Dagi are reservoirs in the Sakhalin Basin. Significant seals include the Okoboski seal, intra Nutov and Dagi seals. Daekurinsky and Dagi are known sources rocks while Machigar, a marine mudstone, is unknown at this time. In areas of neotectonic uplift intrinsic relationship between tectonics and sediment supply may exist.
