Previous HitFracturedNext Hit Shale reservoirs are mainly composed of shales and mudstones,abundant in organic matter, calcareous and siliceous minerals. There are three genetic types of frature which are structural, overpressured and diagenetic contraction ones in the source rocks. The Previous HitreservoirNext Hit caprock are made up of non-Previous HitfracturedNext Hit mudstones, gypsum and halite rock. And anticline and monocline are major trap types.The Previous HitfracturedNext Hit shale Previous HitreservoirTop are believed to have great source potiential due to a great deal of hydrocarbon remained in the source rocks.
