How to extract oil and gas from the deep sea, how to know where natural gas or oil is in the sea, and when was the first exploration
? process for energy sources in the sea and how
Humans have known natural gas and oil for thousands of years, and natural gas does not differ much in its composition from petroleum, as both originate under the same conditions. Both natural gas and oil are often found in underwater or underground fields, and natural gas contains plankton that are organisms You do not see with the naked eye such as algae and primary organisms that have accumulated over the years in the layers of the earth and oceans, and the remains were pressed under the sedimentary layers, and as a result of pressure and heat, these remains and organic materials turned after thousands of years into natural gas and petroleum.
Since natural gas is lighter than petroleum, it forms a higher layer than the petroleum layer, and it is a gas that covers the oil, where it accompanies it and accompanies it, and in this case it is called the associated gas.
How to find out where natural gas or oil is in the sea:
Surface features such as oil or natural gas seeps, or even underwater craters from gas leaks provide essential clues to hydrocarbon generation (both surface and deep in the ground).
But most exploration operations rely on very complex techniques to detect and determine the presence of hydrocarbons using sound equipment through which oil companies identify drilling sites that are likely to produce oil.
Extracting oil and gas from the deep sea
Also, by using geophysics to explore, areas believed to contain hydrocarbons are initially subjected to a specific gravity survey, magnetic survey, passive seismic activity, or regional seismic surveys to discover large-scale features of subsurface geology. Possible positive indicators) for more seismic searches, which work on the principle of time taken to move the reflected sound waves through materials (rocks) of different densities and using the process of transforming depths to determine the features of the infrastructure.
Finally, after confirming the presence of gas or oil, an exploratory exploration well is drilled in an attempt to definitively determine the presence or absence of oil and gas.
How to extract oil and gas from the deep sea:
Oil and gas wells can practically be drilled and extracted from anywhere in the world, whether on land, at sea or in swamps, and from the equator to the frozen polar regions. It is known that oil and gas reserves on land have become limited, and it has become difficult to find new areas containing oil on the surface of the land. Since the area of water on the surface of the earth is more than 70%, it was natural to search for hydrocarbons at the bottom of the sea and extract them from it.
The explorers faced great difficulties in investigating the whereabouts of oil in the coastal and offshore areas at first, but the amazing progress in exploration and drilling techniques in recent years helped to develop and speed up the operations of extracting oil from the sea to a large degree, starting from exploration and exploratory drilling to production and storage in the sea. Marine areas no matter what obstacles, despite sea currents and storms.
It is worth mentioning that the first productive well that was drilled in the world was in the town of Titusville in the state of Pennsylvania in the United States of America in the year 1859 AD, and after thirty-eight years from that date, i.e. in the year 1897 AD, the first offshore well was drilled.
The term hydrocarbon exploration is used to refer to oil and gas exploration carried out by petroleum geologists and geophysicists to search for deposits of hydrocarbon beneath the Earth's surface that exist in the form of oil and natural gas.
The process of drilling for oil or gas is a very expensive and dangerous process. Offshore and offshore exploration operations are generally carried out by very large corporations or by state governments.
Access to oil and gas deposits is also dangerous, but if the drilling, assembly and transportation are done correctly, the benefit will be greater, but if things go wrong, the consequences can be fatal for both workers and the surrounding environment.
As for how gas is extracted, it is extracted from wells that are very similar to oil wells, as there are assemblies of natural gas wells at great distances from the shore. Refining, where it is purified, and natural gas is purified by removing water and other liquids from it, and then the gas is passed through a cooler to liquefy the petroleum, and is filled into bottles as fuel for heaters, cooking and homes, and the rest of the gas is pumped through a supply network or is liquefied by Refrigeration, compression and marketing as liquefied natural gas.
Oil platforms are huge structures on floating floors that are used to produce oil and gas from the deep sea.
The platform is a village on a small island that contains everything the workers need in terms of machinery, equipment, housing, food, drink and electricity generators.
The workers and what they need are transported by helicopter or by boat if the distances are short, and here a distinction must be made between drilling platforms and production and storage platforms.
The platforms are built in ship factories, and then shipped to the place of drilling where they are installed and installed. These platforms vary according to their size, but it is known that their size and technology are proportional to the depth of the water.
