Students and young professionals from different countries presented their results of scientific research on innovations during Youth Technical Sessions. As it was mentioned earlier, all technical sessions were divided into three blocks of the Forum: Leadership, Innovations, and Sustainability. The Innovation Session was split up into three main subgroups: Field Geology and Geophysics. Innovative Approach; Well construction, Drilling and Completion. Era of New Technologies; Oil and Gas Field. Development, Production and Processing.
22 presenters participated in these sessions. Most of them represented Russia and China but also Iran, Kazakhstan, and the USA.
Young professionals had an amazing opportunity to present their papers to the industry experts. Innovations section was especially interesting as the creative projects can impact the Oil&Gas industry in the future. The audience was interested in every paper and asked many questions to the speakers.
Few papers in the Youth Technical Session “Well construction, Drilling and Completion. Era of New Technologies” deserve to be featured.
Anastasiia Liagova (National Saint Petersburg Mining University, Russia) presented the paper “Technology of completion reservoir by drilling multilateral channels”. She said that the main problem with old, marginal wells is the absence of proper and reliable connectivity in the “well-formation” system. It is caused by external impact on the bottom-hole area during well construction and operation.
Anastasiia spoke about the Perfobur system. It is a modern technology of conservative perforation for increase of the flow rate of producers, enhancement of the injection capacity of injectors and elimination of cones of water-gas-oil contacts due to expansion of the filtration area. This method is defined as a mechanical way of pay zone stimulation.
“The Perfobur technology was tested at the wells of the Ural-Volga oil and gas province, where for the first time in world practice it was possible to mill two “windows” in one interval of a casing string, with a small-sized PDM, followed by drilling two channels. The possibility of multiple entry into the already drilled channels for inclinometry, intensification or their overhaul was proved. The actual trajectory of the drilled channels coincides with the calculation with minor deviations”, said Anastasiia Liagova.
Shabnam Mohammadpourmarzbali (Iran) presented the paper “Improved waterflood performance by employing permanent down-hole control devices: Iran case study”. The case under Shabnam’s study was an Iranian oil field located in the south-west part of Iran. Shabnam reported that the results demonstrated significant improvement in cumulative oil production by 6% after 20 years by applying ICV technology. Moreover, it should be noted that, beside an increase in oil recovery, cumulative water production reduced by 21% as a result of using downhole controlled valves. This shows that ICV were more effective in controlling water production rather than increasing oil recovery.
“Application of interval control valves, helps to improve waterflood performance not only by increasing the oil recovery, but also by reducing the water production. It is more efficient in terms of the cost and the risk of the mechanical failure to complete problematic layers or wells with downhole devices”, summarized Shabnam Mohammadpourmarzbali.
