EOR Development Tool

PETRA Development
Development of By-Passed Oil Reserves

PETRA is a patented Petros’ EOR solution for fast evaluation of the remaining oil in place and working out EOR development strategy for brown oil fields.  PETRA allows to start planning and implementation  of effective EOR operations even before reservoir geological and flow hydrodynamic models are available!

RF Patent  № 2044870

PETRA’s Main Goals

• To find By-Passed Oil Reserves;
• To increase Oil Recovery Rate;
• To decrease Energy Consumption;
• To reduce Production Cost.

Information PETRA Needs

• PETRA needs only regular oil field information – production/injection history, general geology and reservoir fluids data;
• No  special field and lab. studies are required.


Information “PETRA” Provides

• Current Energetic Usefulness of each Well; 
• Current Oil Saturation;
• Geological Reserves and their Depletion;
• By-Passed Oil Zones Location;

• EOR Technologies to consider.

Our Products

EOR Technologies

Since 1991 Petros implements most effective methods of Enhanced Oil Recovery (EOR) to increase both current oil production and final oil recovery of oil fields. Nowadays we have at our disposal more than 20 EOR technologies, which annually provide for more than 1 000 000 bbl of incremental oil production in Russia alone.

Water Technologies

Petros Water is a Petros Group’ project on water treatment and environmental protection. The project incorporates the best achievements made for almost a century of academic and applied water science, first in the Soviet Union and now in modern Russia. Today we utilize only market-proven and the most effective technological solutions for water purification and environmental protection.

DEST Geo Prospecting

The technology of Distant Earth Screening (DEST) is truly unique and is one of the most effective methods of prospecting for oil, gas and other mineral deposits. It is based on detecting the impact of minerals accumulations in the bowels of the Earth on the Earth's surface and utilizes the latest airspace technologies Russia is so famous for.

Robotic Fire Fighting

Petros together with Croatian company DOK-ING brings to Indonesia the world wide famous fire fighting robots and other special purposes equipment. The unique remote controlled fire fighting system are developed to fight fires in hazardous and inaccessible areas and to help fire-fighters to do their job in the most challenging and dangerous conditions.

Security Systems

LQTest is designed for security checking of contents of various vessels such as plastic and glass bottles, cardboard packages and other nonmetallic containers. It allows almost instant detection of flammable and explosive liquids without violation of the container sealing. The average check lasts no longer than 5 seconds so the device is indispensable for security purposes in crowded places like airports, railway stations, sea ports and so on.

Tank Cleaning

Petros’ cleaning technologies are set to bring modern, cost competitive and echo-friendly services for cleaning oil tanks off oil-containing solid precipitation, as well as for utilization of petroleum products (oil sludge, liquid waste oil) and the reclamation of contaminated land. They work very well both on and off shore for different oil products…

IT- Solutions

In line with other oil & gas products Petros offers to Indonesian market the best software for seismic, geophysical and geological modeling created in the leading Russian scientific centers. This IT- products have an impressive list of successful application in oil fields operated both by Russia and international oil companies.
