What is oil?
The oil hole is a shaft drilled with a part of the Earth's crust for the purpose of obtaining raw oil products. It has been subject to several phases of development from the well concept after leaving it. Oil holes can be drilled in different places and all do not bring the same product. They will always produce at least a small amount of natural gas that may or may not be trapped for sale. These simple drilling structures, made of bamboo, were replaced when technology and processes were refined. Modern age brought oil wells drilled with stiff cable and then rotary drills. Modern drilling techniques allow almost horizontal drilling and provide access to oil reservations that are deep underground.
The drilling starts as soon as the appropriate place has been selected and all plans have been completed. The hole between 5 and 50 -tiles is thumbs (12.7 to 91.4 cm). This part is the widest segment of the hole, because each subsequent drilled segment will be slightly smaller to reduce any pressure from below. After each section is drilled,It is placed in the opening case made of steel and fastened in place. There is usually no more than five consecutive segments in one hole.
The oil hole must be completed, which means it must be adapted for the production and harvest of oil. The pressure in the reserve is often strong enough to extend the oil on its own, but if the pressure level is insufficient, instead the pump is installed. The oil is then collected by a series of valves known as production trees at the top of the installation. They monitor the oil pressure inside the well and adjust accordingly. Finally, the installation will be abandoned when it is not a longer profitable for operation.
oil well can produce mainly oil or gas and can produce both. There is a small amount of natural gas in each oil well, a by -product of the oil itself. Some wells produce almost completely gas.
oil pitscan be placed on the mainland or at sea. The well function is the same regardless of location, but due to the difficulty of drilling and maintaining a well in the ocean, offshore wells are much more expensive. These holes are drilled only when the presence of a significant amount of oil has been proven. They also require multiple planning and have multiple safety requirements.
