MIOGE 2015: Technology on Center Stage

June 25, 2015

Technical seminars were held June 24 as part of the MIOGE 2015 exhibition on the topics "Methodological bases for applying new classifications for hydrocarbon reserves", "Increasing profitability in exploiting fields with the use of Russian technologies", "Reducing expenditures with new generation mass flow meters and level meters", "Preventative diagnostics, drive connections and equipment for managing and controlling shutoff and control valves from METSO", "Innovative methods for polymer flooding at fields in Russia and the CIS", "Grasis: company products and services" and "New solutions and equipment for increasing reliability and efficiency in oil production and transport". 

The presentation on "Increasing profitability in exploiting fields with the use of Russian technologies", by the OZNA company reviewed methods for preparing products from gas condensate fields. Andrey Kurochkin, the head of the OZNA department of prospective designs, said that preparation makes it possible to increase the value of end products by as much as 30-fold. 

As is known, in as much as the period a gas field is exploited is increased, pressure drops and this results in the need to find solutions that are effective across the entire field life cycle.

One such solutions offered by OZNA is the technology of adsorption drying using block-module equipment. The company is also working to create small-tonnage block-module units for liquifying natural gas.

While the common practice abroad is to emphasize units with power capacity of 0.5m tons and higher, in Russia the great distances involved may require the use of small tonnage units. Today, OZNA representatives said five to six companies are working to manufacture such units.

These units can be used in projects located in remote areas such as the "Strength of Siberia".

For now, the OZNA project is in the design state. Building a small-tonnage unit requires about 300m to 400m roubles. Today similar models of foreign make cost about $8m in Russia and are sold only by a small number of companies.

OZNA also makes small-tonnage units for producing methanol.

A representative of the SNF group of companies told a packed auditorium about tertiary methods for enhanced oil recovery at the seminar on "Innovative methods for polymer flooding at fields in Russia and the CIS". Used widely in the world for over 30 years, polymer flooding is not yet widespread in Russia because of weak developments of the technological process and unsuccessful attempts to develop the technology in the 1990s.

SNF has developed a full assortment of polymers and units for pumping them into formations. A recent long-term contract to sell polymer flooding at the Marmul field, South Oman, proves that this project is progressing successfully.

Three projects in polymer flooding have been carried out with SNF technologies in Kazakhstan by the Alstron, Altair and SNF. Using the technology made it possible to lower the water content and stabilize production. At the Kalamkas field, one of the biggest in Kazakhstan, polymer flooding was used during the Soviet era, but the results then were not as satisfactory as hoped.
