The Higashi-Niigata gas field is located in the coast to offshore area in the northern part of Niigata City, Niigata Prefecture, central Japan. The stratigraphy of the middle Pleistocene to Holocene ...
Source rock and petroleum system of the Paleogene—Neogene forearc basin in the Kakegawa-Sagara oil field, Shizuoka Prefecture, central Japan
fore-arc basin Sagara oil Kurami Group Mikura Group source rock
2009/4/13
Oil fields occur in the Sagara district of Shizuoka Prefecture, despite the disadvantageous geological conditions of a fore-arc setting. We investigated the petroleum system of this fore-arc basin in...
