The occurrence of petroleum Petroleum arising from plant scrap animal carcasses dead piles under ground world.Millions of years of time, until becoming the stones with a high pressure an.Caused by the movement and shrinkage of the stones and the temperature beneath the world.Most of these organic compounds is hydrogen and hydrocarbon.There will be a chemical change slowly turn into a gas and crude oil.Accumulated and absorbed through the pores, such as stones are sandstone and limestone layers into the basin.The rocks below, then gradually accumulates a dense layer between the rocks.Which cannot be absorbed through. Cumulative quantities are typically have 5.25%.Of the volume of rock, because petroleum is compressed with a different rock layers.It tries to insert a skin forming the world cracks of the rock layers.Unless it is blocked with a stone floor texture, which makes it affordable for tai.Global surface geology structure characteristic of stones beneath the surface of the Earth.In the occurrence of petroleum are stones arc hood upside down.(Anticlinal trap) format, the structure of the stone floor, fault (fault trap).Dome shaped structures (domal trap) and décor layer structure image.(stratigraphic trap) The hood arc structure upside down.Due to the bent of the stones, the stones have a shape.The curve is similar to the pan upside down, or turtle oil and gas will be moved.In arc, the bottom pan with stone floor texture cover is arc structure.The hood upside down. Due to the bent of the rock layers.Jewelry image layer structure.Can occur in multiple formats, depending on the change.Conversion of the world in the past. Oil stones catchment will shift between the po.Stone floor textureDome shaped structures.Due to the pressure of the rock salt layer over layer of stone, who normally is the catchment of oil.Dome images. Oil and gas will accumulate beside the layer of salt dome.Picture fault structure.Due to the bent of the stones, rocks, move to a different orientation to the oil.And gas is there because the catchment are stones texture with stone floor, past closed pore.Make oil and gas fields are planted in blocks.
