The antagonistic contradiction between the biological essence of man and the abiological ways in which he obtains energy from the Sun for the creation of a food base and personal habitat is the determining factor shaping the image of our technocratic civilization. In order to address this contradiction in the development of the mineral and raw materials complex, it is necessary that the requirements for environmental security not be imposed on individual operations or processes but form the basis of a promising technological paradigm. In this way, the conservation of the Earth’s natural biota becomes a requirement and an inherent feature of the technologies created and applied. It seems abundantly clear that from a methodological point of view, technological responses to environmental challenges should be sought in the study of systems where these answers have already been obtained. Namely, these answers present themselves in biological systems taking form in nature-like technologies. Recent changes in public consciousness have inevitably led to the greener thinking in all spheres of human activity. The most illustrative ref lection of this phenomenon is the growing interest in nature-like technologies, which are associated with the main aspirations in the settling of a global environmental crisis generated by a long-term antagonistic confrontation between the technosphere and the bio- sphere. In considering the concept of nature-like technologies as a designation of the principal trend in the modernization of the general technological paradigm, it is necessary to distinguish two specific areas. Depending on whether or not the technologies that we use are present or absent in wildlife, we must first consider the construction of technologies by duplicating effective processes already observed in wildlife in the technosphere (nature-reproducing technologies) and, secondly, the creation of technological systems by transferring the effective functional structure of the circulation of matter and energy in biological systems to the technosphere (convergent technologies). The general theory of the creation of “similar to nature“ technologies is presented, based on the well-known principles of homeostatics - methods of maintaining the vital parameters of the interaction of natural and technical systems by controlling the contradictions between antagonists. The main directions of the structural and functional convergence of technical and biological sciences are identified when updating the technological paradigm of industrial development, based on the reproduction in the technosphere of systemic solutions that ensure the functioning of complex biological systems. Regarding the ecologization of the technological paradigm of the mineral resource complex, the methodology of creating an ecologically balanced technology as a multiobject cluster is based on the well-known principles of homeostatics, i.e., on the phased formation of a technological homeostat on the basis of the structure of a biological homeostat with the replacement of its essential elements with geotechnological target analogues. The result of this transformation is the construction of a convergent mining technology for integrated field development. Its use will ensure the development of technical systems that make it possible to limit external environmental impacts owing to the postexploitation self-restoration of natural biota phytocoenoses. The study was supported by the Russian Science Foundation, Project No. 19-17-00034.

A physical model of the process of underground ore mining is substantiated and it is shown that ensuring the geomechanical safety of subsurface development is associated with the technological capabilities of nature-like mining technologies for the reproduction of stable dy-namic structures in the lithospheric objects being worked out. A cognitive analysis of typical geotechnologies is carried out and it is shown that the modern geo-technological paradigm is based on the principles of combining in time the processes that generate a geomechanical dis-turbance in the lithosphere and the processes to overcome the consequences of this disturb-ance. The internally insoluble contradiction of this approach is revealed and it is shown that overcoming this contradiction opens up a very real prospect of creating a fundamentally new concept for the development of underground mining technologies based on the implementation of the global idea of nature-like technologies in the form of the concept of creating convergent mining technologies. With the use of the proposed and developed by prof. The Rodionov model of the lithosphere as a solid body with different-scale inhomogeneities performed a theoretical study of the features of the stress field development during the formation of inhomogeneities with variable volume and zero density and found that in this case, the conditions for the repro-duction of stable dynamic structures will be determined by processes on the external contour of inhomogeneities. This made it possible to substantiate the geophysical and geotechnological ideas of a new technological paradigm of subsurface exploration.

Currently, under the conditions of increasing depletion of hydrocarbon reserves in Russia, it is necessary to consider the resource potential of poorly-researched oil and gas objects as a factor for ensuring the sustainable development of the oil and gas complex, in the context of the concept formation of rational subsoil utilization and a circular economy. The methodology of this study is based on a clear sequence of geological and economic studies of poorly-researched oil and gas objects, including four stages, such as analysis of the raw material base, assessment of the raw material potential, determination of technological development parameters, and economic evaluation. The methods of the probabilistic estimation of oil resources of the forecasted objects with regard to geological risk are outlined. Software packages “EVA—Risk Analysis” and “EVA—Economic Evaluation of Oil and Gas Field Development Projects” were used for estimation. The result of the study is the determination of the geological and economic efficiency of the development of nine hydrocarbon objects with the determination of the order of their further geological exploration, and introduction into industrial development on the example of the poorly-researched region of the Timan-Pechora oil and gas province located in the Arctic zone.

Гидравлический разрыв пласта (ГРП) представляет собой комплексную технологию обработок скважин. При этом его следует рассматривать не только как средство воздействия на призабойную зону пласта (ПЗП), но и как один из существенных элементов системы разработки месторождения в целом. Технологические схемы ГРП, в том числе с последующим химическим воздействием, различаются в зависимости от коллекторских свойств обрабатываемых объектов. Их эффективность определяется условиями, связанными с фильтрационными характеристиками пластов, то есть коэффициентами проницаемости близлежащих и удаленных зон объекта. При этом подход к проектированию обработок ГРП будет различным в низко- и высокопроницаемых пластах, и в этой связи грамотный выбор скважин имеет существенное значение. Для исключения смыкания трещин после ГРП и снятия давления в призабойной зоне пласта (ПЗП) в скважины закачиваются различные расклинивающие агенты. Расклинивающие агенты (проппанты) должны противостоять напряжениям горной породы, удерживая трещину раскрытой после снятия гидравлического давления жидкости разрыва и обеспечивая, таким образом, высокую фильтрационную способность призабойной зоны пласта и дебиты нефти скважин. Обработки скважин проводятся с использованием стандартного нефтепромыслового оборудования и насосной техники. Промысловый опыт ГРП в условиях Верхне-Салымского месторождения (Западная Сибирь) показал его достаточно высокую эффективность. Hydraulic fracturing is a complex technology of well treatment. At the same time it should be considered not only as a means of impact on the bottom-hole zone of the formation, but also as one of the essential elements of the field development system as a whole. Technological schemes of MPG, including with subsequent chemical impact, differ depending on collector properties of processed objects. Their effectiveness is determined by conditions related to filtration characteristics of formations, i. e. permeability coefficients of nearby and remote zones of the object. At the same time, the approach to the design of GRP treatments will be different in low and highly permeable formations and in this regard, competent selection of wells is essential. Various proppantsare pumped into wells to prevent closing of cracks after MPG and to relieve pressure in bottom-hole zone of formation. Proppants (proppants) must withstand rock stresses by holding the fracture open after the hydraulic pressure of the fracturing fluid has been removed, and thus ensuring high filtration capacity of the bottom-hole formation zone and well oil flow rate. Well treatments are carried out using standard oil field equipment and pumping equipment. The field experience of GRP in the conditions of Verkhne-Salymsky field (Western Siberia) showed its rather high efficiency.

The purpose of this brief essay is to outline what can be considered the combination of two essential elements in the realization of Wagner's works: the strength of the myth's plot and the imaginative process in the creation of the artwork. However, it is not a simple presentation of these elements, but how Wagner, when wishing to create the total work of art, is guided by a phenomenological thought.

PVNPs (plant viral nanoparticles) can be used in biological systems for loading and transporting cargo. Small dimensions, high avidity target binding due to numerous targeting ligands per PVNP, configurable and modular physicochemical characteristics, image multiplexing capacity and concomitant capability for massive payload distribution in diverse situations are all aspects contributing to their use. Highly useful materials can be created for future purposes due to physicochemical and genetic alterations. PVNPs can be tailored and loaded for specific applications using physical techniques allowing cargo to be loaded through physical interactions; chemical techniques linking cargo or targeting ligands to external or internal capsid; genetic techniques allowing precise and repeatable manipulations; and combined techniques combining multiple loading methods to generate more options. To optimize loading, selecting the most effective way to match the appropriate cargo is important. Loading and releasing cargo from the particles are essential elements of PVNP-based delivery systems, and both operations are often connected. PVNP's characteristics, the cargo to be loaded, and the rationale for producing the unique nanoparticle all impact whether the techniques are optimal for a given system.

This article deals with the role of developing countries in strengthening the global ecological security, because the focus of environmental crisis has been shifting towards them. Taking into consideration the dynamics of their socio-economic and demographic changes, these countries will determine environmental situation in the world. Ecological crisis in developing countries is subjected to the industrial society formation that is accompanied by heavy demand on natural resources and pollution of environment. The author concludes that inevitable environmental costs of extensive economic growth are multiplied by continuing population growth and poverty increase. Today the developing countries are in extremely hard situation: they won’t overcome economic gap which is the main cause of ecological disruption without accelerating the development. But at the same time, the uncontrolled increase of economic production results in intensification of environmental crisis. It determines the urgent need to shift from the traditional model of industrial development relying on the postulate "growth first clean up later" to the model of "green" development. This economic concept is defined as eco-industrial revolution. In order to carry this task these states have to include the elements of post-industrial "green" development into the model of the industrial type development catch up. In its practical realization this model may cause further differentiation of developing countries and inequality on the global level. The emerging economics of the Asia Pacific region possess enough technological, financial resources and political will to join the "green world". But scarcely the poor countries of Africa or South Asia will demonstrate the same high interest in providing secure ecological development. Sustainable economics will probably facilitate entering the "green world".

It is claimed that our current environmental crisis is one of the imaginations: we are in desperate need of new means to understand relations between humans and their environment. The underground was once central to the evolution of Western environmental imaginations. Yet, this has waned throughout the 20th century as eyes and minds turned up and out. After outlining some of the history of the underground as a site from which to evolve environmental imaginations, the article will explore how the underground might propagate environmental imaginations fit for pressing contemporary environmental concerns. It will do so using examples of three caves evolved through an ongoing arts practice-based research collaboration with artist Flora Parrott. Exploring these three caves, I will explore how the underground offers a powerful site for doing the imaginative work that our current environmental crisis requires, focusing in particular on the challenges of engaging lively earths and deep times (pasts and futures) that have become commonplace in the Anthropocene. To close, the article begins to reflect on the possibilities of collaborative creative geographies as a means to rethink the idea of the imagination within geography, as not just something that might be studied but that these creative practices might enable the creation of much-needed new imaginations.
