IV. Agree or disagree with the following statements:
The basic job of a refinery is to liquefy natural gas.
I don’t think that you are right. The basic job of a refinery is to convert petroleum onto useful products. The refining processes are divided into separation, conversion and chemical treatment. Distillation or separation into fractions is the first step of refining.
Most Russian deposits are located in the central region of the country.
You are not right, I’m afraid. Most Russian deposits are located in the North of our country. The largest gas reservoirs are in Siberia. New supergiant reservoirs were discovered north of Siberia in the Barents Sea and the Kara Sea.

IV. Agree or disagree with the following statements:
Crude oil is moved from the fields to refineries and to storage areas.
You are right. Crude oil is transported from the fields to refineries, storage tanks or residential areas. Pipelines are the main means of oil transportation. But tankers, barges, tank trucks and railroad tank cars are of no less importance.
Natural gas storage is necessary for seasonal regulation of gas consumption.
You are right. Natural gas storage is used for seasonal regulation of gas consumption and supply, as demand for heating is different in winter and in summer.

IV. Agree or disagree with the following statements:
1) Distribution lines are composed of several interconnected pipelines and used to take
products to the final consumer.
You are right. Distribution lines are a part of natural gas system. They are composed of several interconnected pipelines with small diameters. They are used to take products to the final consumer.
2) The petroleum industry is not interested in oil and gas pipelines.
You are not quite right, I’m afraid. Pipelines are the main means of oil transportation. They transport oil from the field where it is produced to the places where it is consumed: to refineries, storage tanks or market areas.

IV. Agree or disagree with the following statements:
Trunk pipelines deliver oil to distant power plants and industrial customers.
You are right. Trunk, or transmission pipelines transport large product volumes over long distances. They deliver crude oil to distant power plants, large industrial customers or populated areas for further distribution.
Pipelines cannot cross all kinds of territories in all parts of the world.
You are not quite right, I’m afraid. Pipelines can be constructed almost everywhere: on the land, under the sea, over the land (on special supports). There are buried pipelines constructed under the land surface.

IV. Agree or disagree with the following statements:
Drilling fluids and pipeline leaks contaminate the air.
You are not quite right. Drilling fluids and pipeline leaks contaminate the soil and the water. But toxic byproduct gases contaminate the air. They cause acid rains and global warming, because they are greenhouse gases.
Russian gas deposits are located in distant and poorly accessible areas.
You are right. Gas reserves are found offshore and in harsh, poorly accessible areas. So, sophisticated technologies and equipment are needed to deliver it to the consumers.
