Crude Oil, Petroleum Products, Gases and Chemical Supervisions

Almost all petroleum products are derived from petroleum distilled in petroleum refineries. Oil refineries produce various petroleum products according to the needs based on the quality and qualities of the crude oil it has.

The most extensive use of oil today is the energy sector. Various grades of gasoline and fuel oil are obtained by processing crude oil. However, chemicals other than petroleum are also produced in refineries. Generally, the products made in oil refineries are as follows:

  • Petrochemical products (For example, plastic is a petrochemical product.)
  • Diesel
  • Gasoline
  • Fuel Oil
  • Tar
  • Asphalt
  • Paraffin
  • Gas Oil
  • Liquefied Petroleum Gas (LPG)

The word meaning of petroleum was formed by combining petra and oleum expressions, which mean stone and oil in Latin. The composition of petroleum densely contains methane, ethane and propane gases. The oil extracted from the underground is still unprocessed. Later, many petroleum products listed above are produced by processing it. The supervision of these services we have mentioned is generally referred to as the supervision of Petroleum products.

About Crude Oil, Petroleum Products, Gases and Chemical Supervision

It is known that oil takes millions of years to form. Therefore, oil resources are precious today. Also, the fact that oil deposits are hidden in the soil’s depths is among the factors affecting the price.


Petroleum products supervision organizations provide services in determining the quality of petroleum and petroleum products, which are among today’s essential energy resources. Determining the quality and characteristics of petroleum products is an area that requires expertise. Therefore, experienced auditors are employed by the audit and supervision organizations in these transactions. Experts provide these services in oil refineries according to specific standards. The procedures performed by auditors when determining the means of petroleum products are as follows:

  • Compliance with API Standards is determined. (Standards set by the American Petroleum Institute.)
  • Compliance with ASTM Standards is determined. (Standards set by the American Test and Materials Association.)
  • Compliance with ISO Standards is determined. (Standards set by the International Standards Organization.)
  • Compliance with GOST Standards is determined. (Standards set by the Russian Federation.)
  • Compliance with other international standards is determined.

As a result of these standards’ determination, crude oil is converted into other petroleum products and sent to the desired companies.

Crude Oil, Petroleum Products, Gases and Chemical Supervision Services

A team that knows the technological infrastructure and the job must handle these services perfectly. Therefore, it is recommended to pay attention when choosing a company and work with companies that do their job well. Petroleum products supervision services are as follows:

  • LPG and Ammonia.
  • Observance of quantities following HM 28, HM29 and IP part XVII standards.
  • Crude oil and other petroleum products.
  • Taking samples following TS 7060 EN ISO 5555 and TS 900-1 EN 3170 standards will be analyzed later.
  • Cleaning, loading and sampling operations of land tankers. Then, unloading and sealing surveys are carried out.
  • Determination of the monthly stock amount.
  • Inhibitor addition process. Afterwards, inhibitor and polymer control in weekly and monthly periods.
  • Procedures for taking samples from each point following the standards.
  • Performing tank cleaning checks. This can also be called ship tanks and shore tanks cleaning control.
  • Surveys of loading, unloading and transfer quantities.
  • Supervision of petrochemicals, animal and vegetable oils.
