Abstract The article considers the approaches to the G&G data interpretation used in the Branch Office of Gazprom International in Saint Petersburg (hereinafter referred to as "GPEPI") when studying the geology aspects of turbidite deposits. This approach is showcased on one of the Upper Miocene deposits of the Nam Con Son Basin in Vietnam, and a conclusion is drawn about the possibility of using this complex technique in the study of sand bodies of any genesis.
ABSTRACT Systematic engineering-geological studies are carrying out, as part of the exploration of polymetallic sulphides (PMS) in the Russian Exploration Area (REA) of PMS at the Mid-Atlantic Ridge (MAR). They are aimed on a comprehensive assessment of engineering-geological conditions of potential deposits of polymetallic sulphides for their exploration and possible future exploitation. In the process of research, the main specific engineering-geological features of the ore fields within the REA that affect the design specifications of the exploration and exploitation machinery were identified. Based on these results this paper discusses the prospects for deep-water equipment design and present experimental examples of the Russian deep-water machinery for PMS study and mining. INTRODUCTION Over the past years, the Russian Federation has been exploring polymetallic sulphides at the Mid-Atlantic Ridge (Cherkashev et al., 2018), basing on the contract with the International Seabed Authority (ISA) established in 2012. Besides such obligations as: PMS exploration, legal and financial provisions, the contract includes the articles by which the contractor has to develop deep-sea exploration and mining equipment and to test them in deep-sea conditions. Contract works at the REA are carried out using the Research Vessel (R/V) Professor Logachev (Fig. 1) belonging the "Polar Marine Geosurvey Expedition" (Saint-Petersburg, Russia). Until 2019, eighteen hydrothermal ore fields were discovered in the REA, which are potential targets for PMS exploitation. In parallel with the ore fields exploration, engineering-geological studies are being conducting (Kondratenko et al., 2017, Kondratenko et al., 2018), which results will determine the requirements for the development of deepwater machinery. The development of new technical facilities relevant to the exploration and further mining operations within the REA involves the analysis of geological structures; dissection of seafloor surface (seafloor roughness); gravitational instabilities; seismic activity and the physical-mechanical properties of the bottom formations. PURPOSE OF WORK The purpose of this work is to identify specific engineering-geological conditions of the PMS deposits within the Russian Exploration Area. Based on this, this study will define the prospects of deep-water exploration and exploitation machinery design adapted for work on the hydrothermal ore fields of PMS of the Mid-Atlantic Ridge.

ABSTRACT A certain number of cracks of various origins are present during the organization of work and movement on the fast ice. During sea level fluctuations, the tidal cracks appear parallel to the coast or encircling ice formations, with grounded icebergs and grounded hummocks. Rather broad cracks form during fast ice movements. The abrupt changes of air temperature, cleaning of ice surface from thick snow layer can be accompanied by thermal cracks. The cracks of technogenic origin appear during loading of ice, hydrostatic disequilibrium of snowice cover and other impacts on ice from the side of vessels and vehicles. Some cracks are dangerous for vehicles and people because of reduced ice-load bearing capacity, while a large number of visually observable cracks allow to cross them without any restrictions. The experience of ice-technological work performance and cargo transportation along fast ice in case of cracks presence in the ice cover is summarized in the report. To estimate the degree of ice strength decrease after cracks congelation in the ice basin of the Krylov Research Centre in Saint-Petersburg, a set of laboratory experiments was performed to estimate the ice bending strength of the congealed cracks and unbroken ice under the conditions of various water salinity and ice formed from it. The estimations of ice breccias strength relative to the strength of unbroken ice of primary structure were obtained. INTRODUCTION Fast ice is a form of stationary ice, nevertheless it faces dynamic impacts, which result in deformations of ice cover and forming cracks. Tide cracks, which occur due to vertical movements of ice cover during sea level fluctuations, represent a characteristic feature of the sea fast ice. Besides tide cracks, in fast ice there are cracks formed as a result of horizontal shears, thermodynamic processes in ice cover, natural and anthropogenic loads on ice cover.

Lestev NDCS Neftepromсhim, RF, Kazan Research, the results of which are presented in the article, are devoted to the detection of LHOS in naphtha and chemical reagents and are due to stricter requirements for the quality of marketable oil in accordance with the Technical Regulation of the Eurasian Economic Union On the Safety of Oil Prepared for Transportation and (or) TR EAEU 045/2017. The practical significance of the work is to reduce the risk of the formation of volatile organochlorine compounds in marketable oil due to the use of chemicals. As a result of the studies, the formation of volatile organochlorine compounds (the so-called secondary organochlorine compounds) was discovered due to the decomposition of salts of Quaternary ammonium bases contained in some oilfield chemicals.
