We became participants in one of the largest international events of the oil and gas industry in Russia - "Tatarstan Oil and Gas Chemical Forum 2022", which was held from August 31 to September 2.
This year, the Tatarstan Petrochemical Forum-2022 was dedicated to the issues of decarbonization and digital transformation of the oil and gas industry.
The forum is an effective platform for interaction between industry enterprises. Here you can exchange ideas and get up-to-date information on key industry topics.
The main focus of the Forum business program was aimed at discussing decarbonization issues: innovation, digitalization, import substitution.
We thank the exhibition center "Kazanskaya Yarmarka" and all the organizers for the business atmosphere of the forum, and the speakers for interesting and rich reports.
Ilshat Sharapov, Chief Geologist of CJSC Gradient, took part in the XI International Scientific and Practical Conference GeoSOCHI-2022. Actual issues of geology and geophysics in the oil and gas industry.

On May 19, 2021, the founder of Gradient CJSC, the head of science and new technologies, died suddenly,
Evgeny Vasilyevich Biryaltsev.
During his 60-plus years, he managed to do a lot, but how many more plans are still not implemented... For us, Evgeny Vasilyevich has always been an ideological leader who not only made brilliant discoveries, but also embodied them in really working technologies that are in demand on the market. He successfully combined a theorist and a practitioner, a politician and a workaholic, a great speaker and an attentive listener, a manager and an economist, and many others... and always combined successfully. He could explain the most complex things in simple words, and after talking to him, there were always explanations of problems and ways to solve problems.
Evgeny Vasilyevich lived a bright creative scientific life and left behind a huge legacy in the face of his students, working technologies, successful companies and much more.
The passing of Evgeny Vasilyevich is a great loss for all of us! We will always remember him as a bright and open person, the memory of him will live in our hearts, our minds and our deeds. We grieve together with our relatives and friends. Vivid memory.
The annual inspection audit of the integrated management system for compliance with the requirements of ISO standards has been successfully completed.
Verification was carried out in respect of geophysical surveys in three aspects:

JSC "Gradient" – is the geophysical company which conducts microseismic surveys for assessment the hydrocarbon potential of geological objects and solves technological problems in hydrocarbon fields. The company is the developer and owner of the patent on the Low Frequency Seismic Sounding (LFS) technology. The company is actively use supercomputer processing complex, which allow to implement full-wave 2D and 3D-numerical simulations of wave propagation in the geological media.
During the existence of the company, 96 wells were drilled by recommendations of LFS method, 82 of them confirmed the forecasts. Success rate of LFS method more than 85%.
To improve the efficiency of exploration it is necessary to integrate of 2D and 3D seismic surveys with microseismic surveys using LFS technology, that allow to identify hydrocarbon deposits and create a complex that has no analogues in world practice.
Further development of MS researches will allow control the exploration of hydrocarbon deposits.

LOW-FREQUENCY MICROSEISMIC STUDY IN THE TIME DOMAIN IN THE EXPLORATION FOR HYDROCARBON DEPOSITS.
E.V. Biryaltsev, V.A. Ryzhov, D.A. Ryzhov, I.R. Sharapov
Abstract. Known methods of spectrum analysis of natural microseisms in the exploration for hydrocarbon deposits. We propose a modification of these methods, in which the MS analysis is performed in the time domain by means of correlation analysis of the observed MS and MS model obtained by numerical simulations for different variants of the geological structure at the point of the study. We present the proposed method of analysis and present the results of its application to the area of research in the Republic of Tatarstan.
Our company passed the final checking of the quality management system, the system of ecological management and the control system in the labor protection and professional safety (ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007)
8-11 November at the 10th annual international Conference & Exhibition “Galperin readings – 2010”. Innovative technologies and fundamental researches in 2D, 3D, VSP well-surface exploration and seismology. (Moscow, Central Geological Expedition) The special subject of the conference is the integration of surface and borehole seismic surveys with data processing and interpretation software (3D+VSP), and also problems of applied seismic based on fundamental theory. The 9th of November 2010 JSC “Gradient” will take part in conference and will represent the report on a theme: "LOW-FREQUENCY MICROSEISMIC RESEARCHES IN TIME DOMAIN FOR INVESTIGATION OF THE HYDROCARBONS DEPOSIT " (Å.V. Biryaltsev, V.A. Ryzhov, D.A. Ryzhov, I.R. Sharapov)
International scientific conference: “Innovative technologies - the basis of the Strategy public corporation Gazprom Neft”. E.V. Biryaltsev and I.R.

Release of the special edition of «Seismic Technology» journal covering the ANCHAR microseismic infrasonic technology of oil and gas prospecting. The edition was dedicated to the 15th anniversary of “ANCHAR” Company. JSC “Gradient” took part in preparing of journal’s informational content submitting the article “Modeling of ANCHAR effect in the low-frequency seismic sounding” (E.V. Biryaltsev, A.A. Vildanov, E.V. Eronina, V.A. Ryzhov, D.A. Ryzhov, N.J. Shabalin). The article referred to the ANCHAR effect-based method of the low-frequency seismic sounding and provides information about phenomenology of an effect and it’s theoretical background, cites the results of numerical modeling in comparison with actually observed results, describes main technological aspects of the method and brief geological results of performed works.
JSC “Gradient” team congratulates the colleagues from “ANCHAR Co” with their 15th Anniversary and wishes the development of their technology, efficiency improvement and financial well-being!!!
