ENERGAS group of companies debuted at Skoltech

9 October 2018

On October 3, the Industrial Day Skoltech-2018 took place in Moscow at the territory of the Skolkovo Technopark for the second year in a row. This event was timed to the end of the Skoltech graduate students practical training program "Immersion in Industry 2018".

At the poster session of the projects of this program, they told about all 147 projects implemented by students this year in 102 companies in 8 thematic areas.



As part of the Industrial Day Skoltech-2018, a round table on hydrocarbon production was held with the participation of representatives of the scientific centers of Rosneft, Gazpromneft, Novatek. It was held in the format of a meeting of the Scientific and Technical Council of the Skoltech Center for Hydrocarbon Recovery with a discussion of two topics: Big Data in the oil industry and geomechanics. Presentations were made by leading professors of the Center on advanced technological trends in these areas.

The moderator of the discussion was professor, director of the Skoltech Center for Hydrocarbon Recovery, Mikhail Spashenykh, who in his analytical articles and speeches repeatedly substantiates the most important aspects of the present and future of the oil and gas industry in our country and in the world.



So, Professor M. Spashenykh stands for and confirms the following:

«The main task of the Center for Hydrocarbon Recovery, as a whole of Skoltech, is to train specialists and develop technological solutions in those areas that will be in demand in the near future and which are not available today.

We are engaged in the technology of exploration and development of hard-to-recover reserves. They will allow you to find "deposits within the fields", that is, to increase the oil recovery factor is one topic. Technological solutions for the exploration and development of unconventional reservoirs, such as the Bazhenov formation, are another topic. In addition, of course, technological solutions for work in the Polar Regions, on the Arctic shelf, which will reduce risks and ensure production, we are engaged also in this, developing technologies related to gas hydrates. That is, it focuses on HTR - hard-to-recover and unconventional reserves.

Our Center for Hydrocarbon Recovery began with meetings initiated by us, in which we asked the companies: what does not suit you, what expertise do you lack, where do you need new knowledge? There was formulated several directions for us.

One of them is geomechanics - the science of the properties of subsurface rocks and the use of this knowledge in oil and gas production. 10-15 years ago, oilmen did not pay special attention to geomechanics, but now everything has changed: without this knowledge, the extraction of hard-to-recover resources is impossible. When hydraulic fracturing is carried out, it is necessary to understand very precisely the limits of the strength of rocks, how the fracture will pass, if it is initiated, how to produce cracks of a given size. In addition, drilling unconventional reservoirs is an extremely difficult operation, for which, again, it is necessary to predict accurately the mechanical properties of the rock.



During the development of the field, compaction may occur - mechanical subsidence of the reservoir because of a decrease in reservoir pressure. Such processes need to be predicted and prevented. In response to this request, we have established a direction of geomechanics in the Center; we are developing new simulators of hydro-geomechanical processes necessary for the development of hard-to-recover reserves.

The second request of the companies is connected with the creation of expertise and training of specialists in the field of enhanced oil recovery methods. It is about different approaches: chemical, thermal, gas, complex.

For example, in the case when oil is displaced from hydrophobic rocks (which is especially important for Eastern Siberia), it is necessary to change their wettability by adding surfactants. In some cases, production can be increased by increasing the viscosity of the injected water, adding polymers to it. In the case of working with heavy oil, it must be heated so that the viscosity decreases and the oil can flow. One of the warm-up technologies is injection of high-pressure air into the reservoir (in Russian terminology, the thermal gas method). Air injection leads to the start of the in-situ combustion process. In-situ combustion is a very efficient technology in terms of energy consumption: only air is supplied, and the heat generated during this is completely consumed to heat the formation.

For many fields, promising technologies to increase oil recovery associated with the injection of coolants - hot water or steam. A very promising production technology is based on the injection of carbon dioxide, which in a supercritical state is a fantastic solvent and, mixing with oil, ensures its driving-out».

For the first time, the ENERGAS group of companies participated in these events as observers. Based on the results of their work, ENERGAS representatives concluded: the scientific and technical future of the oil and gas complex of Russia is largely laid in Skoltech.



REFERENCE. Skoltech Center for Hydrocarbon Recovery (SCHR) was established by decision of the Board of Trustees of Skoltech in December 2013. The main goal of SCHR is to provide international standard educational programs, research and innovative projects in the field of exploration and production of unconventional and hard-to-recover hydrocarbon reserves.

The main directions of research, educational and innovation activities of SCHR are geomechanics, methods of enhanced oil recovery, geophysics and petrophysics of non-traditional reservoirs, thermal petrophysics, gas hydrates, hydrodynamic and geomechanical modeling.

Following the Skoltech strategy, SCHR develops cooperation with world leaders in educational activities, including Texas A & M University, USA; University of Calgary, Canada; Heriot-Watt University, Scotland, and others. SCHR partners are also well-known Russian universities: Moscow State University, Bashkir State University, Russian State University of Oil and Gas, as well as institutes of the Russian Academy of Sciences.

SCHR's main industrial partners are the largest Russian oil and gas companies, including Gazprom Neft, Gazprom, Lukoil, Rosneft, Tatneft, Novatek and other mining and service companies.
