Russia (bbabo.net) - The digital transformation of the Russian fuel and energy complex is not a tribute to fashion, but a vital necessity. This is especially true of oil production, which is becoming more difficult to extract every year. All the more so at a time when environmental requirements are becoming more stringent and all countries are beginning to fight to reduce their carbon footprint.
"The main point of digitalization is to increase efficiency, which means to achieve the lowest costs, including energy costs, as well as the lowest emissions into the atmosphere. Digitalization is one of the most obvious ways to reduce our impact on the environment," said Russian Deputy Minister of Energy Pavel Sorokin.
According to expert estimates, in recent decades, the oil recovery factor (ORF) in Russian oil production has been steadily declining, and now it is no more than 30 percent. One of the reasons is the gradual development of areas with maximum oil recovery. For existing fields, digitalization can become a real "second wind", says Marina Mosoyan, senior consultant at VYGON Consulting.
“It will optimize the well stock, excluding the unprofitable wells, improve the efficiency of equipment operation and repair, select the optimal technologies for increasing oil recovery,” the expert explained. digital solutions in general will reduce exploration and production costs by 15-20 percent, operating costs by 10-15 percent for comparable categories of reserves and assets. The potential effect for the industry by 2035 could amount to 150-200 billion rubles. "
Barclays is expecting even greater benefits from digital technologies, believing that they will allow global oil producers to increase oil recovery by 10 percent and reduce the cost of production by the same amount. This will save about $ 150 billion annually.
"Large oil companies in the world and in Russia regard digital technologies as one of the main conditions for successful business, sustainability and competitiveness. The key effects of their implementation are reducing the cost of production, transportation, refining and marketing of oil, optimizing key business processes, increasing efficiency and the quality of decision-making, "notes Dmitry Pilipenko, deputy general director of SAP CIS." A pioneer in the implementation of digital solutions, BP estimates the effect from them at 2-4 percent to operational benefits, and Gazprom Neft predicts up to 5 percent additional effect on EBITDA by 2022 year ".
According to the Ministry of Natural Resources and Energy, digitalization will help reduce exploration and production costs by 10-15 percent, speed up the commissioning time by 40 percent Among the technological solutions that are now being actively implemented and help to increase production, experts point out the digital twin of the field ... “Thanks to this technology, it is possible to test the location of a well in different formations and see how its flow rate will change,” explains Anton Ablaev, Director of Acceleration for Oil and Gas at the Skolkovo Foundation for Energy Efficiency Technologies. planned hydrocarbon recovery factor ".
The expert cites the example of the Salym Petroleum field, where all wells have pressure sensors and depth gauges. At a frequency of several times a minute, data are collected and fed into a digital model of the field. The efficiency of its development increases by 3-7 percent, and this is not the limit, Ablaev is sure. In his opinion, with the help of digital technologies it is possible to increase oil recovery and economic efficiency by 15-20 percent.
All major Russian companies have fields with wells equipped with sensors. For example, the digital model of LUKOIL's Vatyeganskoye field involves the creation of digital twins for more than 3,000 wells and covers the entire production chain. Kondaneft (a subsidiary of Rosneft) is trying to optimize production using artificial intelligence. In May, she began building a neural network to process information from equipment installed in wells. Based on the data obtained, the digital system selects the optimal well operation mode. According to the company, the use of AI methods can increase the company's oil production by more than 50 tons per day.Digital technologies are also involved in the development of new fields. According to the Ministry of Energy, digitalization will help reduce exploration and production costs by 10-15 percent, as well as speed up the commissioning of facilities by 40 percent. Digital support will be especially useful when developing hard-to-recover oil reserves (TRIZ). Now their share in production is small - less than 8 percent, but in the total volume of proven reserves it is more than 65 percent. According to Pavel Sorokin, in 10 years almost all oil produced in Russia will be classified as TRIZ. And the cost of production will increase significantly.
“Most of the hard-to-recover reserves can be developed using digital solutions,” notes Marina Mosoyan. “For the pre-Jurassic complex, the effect is estimated at minus 70 percent of the cost of prospecting and exploration. the quality of design and engineering. This will cut the lead time for large projects in half. "
For the development of TRIZ, horizontal and multilateral wells are increasingly used today, which are much more expensive than conventional directional wells. Gazprom Neft decided to improve drilling efficiency with the help of the Digital Drilling Project. Three hardware and software systems control drilling parameters, automate the load on the bit and adjust the borehole trajectory. This technology made it possible to increase the well penetration rate by an average of 28.5 percent.
Drilling wells horizontally without innovation is practically impossible, says Dmitry Pilipenko. “Wells are monitored in real time, the drilling trajectory is adjusted based on powerful predictive models,” he explains. risks ".
“This year, the total volume of investments in oil and gas in the world amounted to $ 2.1 trillion,” notes Anton Ablaev. “If thanks to digital technologies we save even 1-2 percent, this is billions of dollars. there is still another choice, how to develop more complex ones. Therefore, the role of technologies, including digital, is becoming more and more relevant. "
