Federal Intellectual Property Service (ROSPATENT) granted a patent to ONHP for the invention of a ground-breaking way to recover Associated Petroleum Gas (APG) produced during offshore oil production.

Associated Petroleum Gas is a mixture of hydrocarbon and non-hydrocarbon components dissolved in petroleum, which are released during its production. Efficiency increase of Associated Petroleum Gas usage is a key priority of oil and gas refining companies.  

A simple but irrational way to utilize valuable hydrocarbon raw materials is its burning at flare. With such approach, APG is an oil field waste. Russian Federation is among the “leaders” in the number of flares (it takes third place after the USA and Canada). There are 1814 flares where APG is burned.

Burning of Associated Petroleum Gas is accompanied by the release of large volume of pollutants (more than 250) into the atmosphere, which negatively affects ecological situation in the area of oil and gas production and is very undesirable for the Arctic offshore regions.

Most typical methods of beneficial APG use are:

- re-injection into the reservoir to increase the pore pressure and oil output,

- use for own needs at the field and by local consumers for heating and power generation,

- supply to the gas pipeline system, and

- integrated processing at plants.

The method developed by ONHP engineers is very effective and applicable for offshore oil and gas sector, the development of which is hampered by large penalties for burning or dispersing APG.

Patented method eliminates emissions of Associated Petroleum Gas into the atmosphere in form of combustion products, and is also more rational in comparison with other existing methods of utilization.  

ONHP patent is the result of collaboration between company engineers and basic faculties of Corporate University.
