“Sevmash” is one of the biggest Russian shipbuilding enterprises. Its capacity enables high-tech and knowledge-intensive projects to be fulfilled, such as manufacturing of spent nuclear fuel containers, building of modern nuclear-powered submarines (NPS) and marine engineering structures. The enterprise has mastered manufacturing of offshore platforms for oil and gas field development in the Arctic. Now “Sevmash” continues construction of nuclear strategic and multi-purpose submarines of the fourth generation “Borey” and “Yasen”. The article deals with the formation and development of non-destructive testing services from its beginning to the present day. Since 1950s, the radiography of hull structures welded seams and pipelines joints was the main testing method. In 1970s construction of new generation nuclear submarines began; it was necessary to create gamma flaw detectors of new design and they were created within 15 years. Besides in 1970s the active period began for development of ultrasonic testing instruments. In 1970s–1990s, concurrently with radiographic and ultrasonic techniques, testing of welds during the welding process with an acoustic emission method was carried out. In 1990s magnetic particle inspection of welded joints, radiation monitoring, leakage testing with the use of helium leak detectors and vacuum chambers had been extensively developed. The bubble vacuum method of welded connections testing was widely used in the process of repair and re-equipment of surface crafts. Today “Sevmash” actively re-equips its production facilities. It gives “Sevmash” the opportunity to built ships that meet the highest demands.

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.

Traditional pipeline technology will be severely challenged as design-operating pressures continue to rise and gas field developments occur in more remote locations including the arctic. Cost-effective solutions to these issues can be found through innovative designs using new technology and its implementation. Some of these designs have considered the use of high-pressure natural gas pipelines resulting in the development of high strength steel. In order to meet these increases in pressure TransCanada and JFE/NKK have been working extensively on the application of X100 (Grade 690) linepipe and this has culminated in the construction and installation of a X100 project in the fall of 2002. This paper will discuss the development of the related research projects that allowed the successful completion of the field project. The topics will include the material properties and fracture control plans for X100. In addition the approach to strain based design for X100 will include the analysis for both the tensile strain limits (weld mismatch consideration) and compressive strain limits (i.e. buckling capacity). The development of the field welding process will also be covered. The paper will discuss the implications of using X100 from the perspective of the successful field project and the application of a strain-based design.

Increasing the field development efficiency of fractured reservoirs is a contemporary issue. This paper presents fundamental and exploratory research results in this field using modern high-tech experimental equipment from the “Arctic” Scientific Centre at the Saint Petersburg Mining University. Oil reserves in fractured reservoirs are enormous; however, they are classified as hard-to-recover. The before-mentioned reservoirs require a specific approach when selecting technologies to improve the efficiency of their development. In this paper, as a solution to the problem under discussion, we propose the use of a physicochemical method of developing fractured reservoirs based on the injection of a water shut-off agent to exclude highly permeable water-conducting fractures from the drainage process. This technology makes it possible to effectively include and develop previously undrained reservoir areas by directly controlling their filtration properties with the use of new highly efficient and ecologically safe chemical reagents and process fluids.

Ensuring stability of subgrade soil under engineering structures is a critical task at oil field development projects in the Arctic. It is largely determined by the state of the permafrost influenced by natural and man-induced changes to the temperature regime. The issue of permafrost stability forecasting is still underexplored, this entailing a number of challenges for construction and trouble-free operation of facilities in the Far North. The Ardalin Oil and Gas Field (AOGF) is the only project in the Nenets Autonomous District (NAD) where results of extensive temperature measurements carried out in special thermometric wells have been accumulated over a lengthy period of over 20 years. This article contains the findings of thermometric monitoring of the top layer of soil with an average depth interval of 20 metres. Changes in the permafrost temperature regime, in both the presence and absence of sand (soil) filling, over the study period are described in the article. Natural physical and climatic disturbances that rule out the possibility of maintaining a continuous permafrost temperature are identified. In addition, the key sources of man-induced impact on the top layer of permafrost at the location of the AOGF production infrastructure facilities are analysed. This analysis resulted in recommendations that might be of help during design and construction of engineering works in the European North of Russia and serve to minimise thermal impact on frozen ground. Preserving the permafrost layer in its original natural state will help ensure stability of the subgrade of buildings and structures, thereby reducing the chances of any accidents.

A detailed analysis of the existing methods of cleaning and preparation of produced waters of oil and gas fields has been carried out and the most high-tech methods have been considered in detail. The prospects for the use of produced water as a technological reserve for increasing the efficiency of oil and gas field development are shown. It is noted that the methods of physico-chemical and mathematical modeling can be effectively used to improve the electromembrane technologies. At the same time, many theoretical questions require further, deeper study.
