Natural gas is primarily composed of methane (CH4), which typically makes up around 70-90% of its composition. However, natural gas can also contain smaller amounts of other hydrocarbons and non-hydrocarbon gases, including:

1. Ethane (C2H6)
2. Propane (C3H8)
3. Butane (C4H10)
4. Pentanes and higher hydrocarbons (C5+)
5. Carbon dioxide (CO2)
6. Nitrogen (N2)
7. Hydrogen sulfide (H2S)
8. Helium (He)

The exact composition of natural gas can vary depending on the source and location of extraction.

1. Ethane (C2H6)
2. Propane (C3H8)
3. Butane (C4H10)
4. Pentanes and higher hydrocarbons (C5+)
5. Carbon dioxide (CO2)
6. Nitrogen (N2)
7. Hydrogen sulfide (H2S)
8. Helium (He)

♦️In the context of an oil field, a "catwalk" is a ramp or platform located at the side of the valve drilling rig. This structure is used for laying down pipes, which are then lifted to the derrick floor using a catline (a type of cable) or an air hoist. The catwalk plays a crucial role in the handling and transportation of drilling pipes, facilitating the process of moving heavy equipment safely and efficiently onto the rig.

♦️The Manifa Field in Saudi Arabia is one of the world's largest offshore oil fields, located in the Arabian Gulf. By 2011, its production capacity reached 900,000 barrels per day. The field comprises 350 wells, some exceeding depths of 32,000 feet. It features 27 artificial islands connected by 41 kilometers of bridges, a design that preserves marine life and the ecosystem in Manifa Bay.

♦️Blanket Gas Cover

A content or quantity of gas placed on top of a liquid stored in a tank container to protect the liquid from air pollution, to reduce the risk of explosion, or to increase the pressure of the liquid. The gas source used in blanket gas is located outside the vessel.
