Petroleum weewee injection - Essay ExampleFor the formation of this crude rootage worth producing various geological elements be required. These elements include porous reservoir rock which stores the petroleum, organic rocks which atomic number 18 the source of generating the particle accelerator or cover and lastly roughly kind of traps to prevent leaking away of the cover and gas (Souza at el). Usually these traps are found in predictable areas like next to faults, top of anticlines and under keystonestone beds. The traps are of three types structural, hydrodynamic and stratigraphic traps. Hydrodynamic traps are not common types of trap. They usually caused by water pressure differences that are as a result of water flow which creates a tilt of hydrocarbon water contact. Structural traps are bents and alter areas beneath the surface that hold oil and gas. Mostly the traps are simple domes or more change faults. A fluid, which is water, oil or gas, fills the pores. Gas move to the top as it is the lightest, followed by oil whence water stays down. Stratigraphic traps are depositional in nature as they are formed frequently by porous sandstone body or limestone getting enclosed in shale. The oil and gas are unplowed from getting away by the shale. Petroleum reservoirs are generally located beneath the surface at 1000 to 30000 feet. They vary in size, type and age. They a great deal extend over hundreds of kilometers, plus include a number of oil come ups spread out across a big area. Petroleum reservoir formation can be divided into planktons, algae and protein rich life buried beneath sand layers and mud at source rock this involves sand accumulation, lastly buried reside transfer into watery hydrocarbons. Topographical characteristics play an important role in the petroleum reservoirs formation. Petroleum reservoirs were discovered in the nineteenth century when Edwin Laurentine discovered that rock oil produces a distilled product for lanter ns he then did the first well drill in 1859.The success of this drill which was close to an oil seep motivated further bore in the same area, which soon led to same explorations in other places. The growing need for petroleum products led to petroleum reservoirs drilling in several states and countries. Petroleum reservoirs can be accidentally discovered, this for the most part happens when oil seeps to the surface or it seeps into water supply thereby exposing its presence in that area. In some instances, it is necessary to deliberately explore different regions by the application f geographical and scientific acquaintance with the intention of discovering locations A petroleum reservoir may be discovered by accident, as has happened when the oil seeps to the surface or when the oil seeps into water supply, consequently revealing its presence in that location. Other times, it is often necessary to intentionally explore different regions through the application of scientific and geographic knowledge with the judgment of discovering other places that may contain petroleum reservoir. Petroleum exploration and production which is the way to get gas and oil is performed by geologists, engineers and geophysicists. Geologists examine areas of the earth where sediments gather together. They then analyze the areas of interest closely to kick downstairs out whether or not reservoir rocks and source rocks are present in the area. Examination of the rocks is through at the earth surface and drilled wells in the area. Geologists also use satellite images
