Crude oil is a very lucrative product of the remains of animals and plants millions of years ago. The dead organism (s) begins to sink deeper into the seabed, and the sediment is compressed with mud layers and undergoes a chemical process that turns dead matter into crude oil and natural gas.
Earth movement begins to seize this oil and natural gas between reservoir rock layers. These include:
1) Folding – Horizontal motions with compression.
2) Failure – The rock layers begin to crack and move one side up or down.
3) Pinch – A single layer of rock is pressed upwards to the barn rock.
Oil companies are an integral part of the oil and gas industry because they are engaged in exploration and production of energy, one of the world's most valuable resources. Bringing energy to retail distribution is a very profitable business, but it is a very complex process. Geologists are experts in the exploration of crude oil. The goal of geologists is to find areas that provide the perfect environment for catching oil, for example, access to the reservoir rock. Geologists can measure minute-to-minute changes in the earth's gravitational field, indicating that oil flows. Another way to find oil and gas is to use 3D and 4D seismic imaging processes that generate shock waves capable of penetrating through hidden rock layers, and then reflected and measured and analyzed again. When there is a promising "oil strike" that can yield significant returns, the position coordinates are recorded with GPS for land and / or winds when the discovery is over the water.
Oil drilling is simplified
When a profitable oil field is identified, geologists study the perimeter boundaries and conduct environmental studies. It is during this period that the oil company obtains the necessary names and drilling rights to begin oil production and then commence drilling operations. The process is quite complex and beyond this article, but in simplified terms:
1) The soil is prepared for removal from trees and other obstacles. At this time, access roads are being built to allow the traffic.
2) Water is very important during the drilling process, so if there is no access point nearby, the wells will be drilled.
3) Reserves for drilling mud and stone mud are drilled during the drilling process. This supplement is covered with plastic to prevent further environmental contamination.
4) A large number of secondary holes were drilled to open the main hole. A rectangular hole called a "basement" was dug near the original drilling hole. The purpose of the basement is to provide access to the original hole for workers and their specialized equipment.
5) The rig begins with drilling holes.
