Objective. The removal of asphaltene deposits at oil and gas facilities is one of the urgent and important problems and requires significant material and labor costs. It is possible to reduce costs by creating and implementing effective technical means, which requires an in-depth study of the processes of organic matter deposition at oil and gas facilities and their use as a secondary raw material. Methods. This paper discusses modern views on the state of the problem of asphaltene deposits in oil shipping and storage equipment and possible ways to solve it. The paper provides an overview of various ways to clean shipping and storage objects from asphaltene deposits: chemical (adding additives, solvents), thermal (heating by special devices or injection of superheated steam during exploitation), mechanical (using scrapers and pistons), and refers, among other things, to scientific works on the use of ultrasound to accelerate the removal of deposits. Results. The paper considers methods for removing deposits, as well as using the positive effect of the removed layer as a secondary energy source. A procedure for model calculation of the use of ultrasonic equipment to remove deposits has been developed. As a result, the deposit melting front velocity was determined depending on the duration of exposure. Conclusion. Taking into account the positive world experience, the level of development of the ultrasonic method for removing asphaltene deposits in the oil and gas industry and the use of asphaltene deposits as a secondary raw material, this area needs further development. The widespread implementation of equipment and, from the standpoint of rational use of natural resources, the use of deposits as a secondary raw material will increase cost efficiency and equipment efficiency, and reduce environmental impact.

Market Relations

In the recent years, due to the introduction of new Technical Regulations in the Oil and Gas Industry in 2008, high technical and environmental performance values were set to be met by production volume and by the quality of hydrocarbons and a variety of oil products coming from the fields to factory processing and trade parks. The presence of a powerful raw material base, the shortage of petroleum products and the development of market relations create objective conditions for increased use of a variety of natural hydrocarbons, for improved technological schemes of oil preparation and oil processing on the oil fields and for modernizing the equipment used. On small and remote oil fields, which for economic reasons cannot be linked by transport pipelines, a complex system of preparation of liquid hydrocarbons is used with the ultimate goal of obtaining some refined products such as gasoline, diesel fuel and furnace oil.

To serve the pumping and storage needs of its customers; Enbridge operates more than 25 terminals and 150 pump stations across North America. In each of these facilities, small diameter (NPS 6 and smaller) piping is used in auxiliary systems including instrumentation, measurement, and product re-injection. Traditionally, in the design of facilities, this small piping has received less attention than large diameter process lines and, during construction, has typically been field run based on standard installation details. This, in conjunction with 65 years of changing design and construction philosophies, as well as asset acquisitions, has resulted in a wide variety of installation configurations across the Enbridge liquids system. The Small Diameter Piping Program in the Facilities Integrity group centrally manages the integrity of all small diameter auxiliary piping across the Enbridge liquids system. Historically, the management and remediation of small diameter systems has been based on addressing specific installation types identified through incident investigations. While generally effective at minimizing re-occurrence, this approach has been limited in its ability to proactively identify installations that should be addressed. In support of our goal of zero incidents, Enbridge has developed a proactive methodology for the inspection and prioritization of small diameter auxiliary piping. Installation types are evaluated on their susceptibility to specific damage mechanisms. An inspection and prioritization model was developed through the combination of internal lessons learned and prioritization methodologies outlined in industry publications, specifically those from the overseas oil and gas industry. This model, sets a standardized process to assign a likelihood of failure (LOF) score to individual small diameter installations of specific types and/or functions. Presently, likelihood of failure scores are used to identify installations requiring remediation, and to most effectively prioritize system-wide remediation activities. Over time, these scores will also be used to demonstrate an overall reduction in the likelihood of failure for small diameter piping in the Enbridge liquids pipeline system.

In 1972, carbon dioxide (CO2) began to be captured from natural gas processing plants in West Texas and transported via pipeline for enhanced oil recovery (EOR) to oil fields also in Texas. This marked the beginning of carbon capture and storage (CCS) using anthropogenic CO2. Today, there are 22 such large-scale CCS facilities in operation or under construction around the world. These 22 facilities span a wide range of capture technologies and source feedstock as well as a variety of geologic formations and terrains. Seventeen of the facilities capture CO2 primarily for EOR. However, there are also several significant-scale CCS projects using dedicated geological storage options. This paper presents a collation and summary of these projects. Moving forward, if international climate targets and aspirations are to be achieved, CCS will increasingly need to be applied to all high emission industries. In addition to climate change objectives, the fundamentals of energy demand and fossil fuel supply strongly suggests that CCS deployment will need to be rapid and global. The oil and gas sector would be expected to be part of this deployment. Indeed, the oil and gas industry has led the deployment of CCS and this paper explores the future of CCS in this industry.

The relevance of the study is explained by the need to use unmanned aerial vehicles (UAV) to serve engineering and geodetic tasks in the oil and gas industry. Airborne photographic survey using unmanned aerial vehicles is currently an advanced technology in the area of geodesy and it replaces such methods as tacheometry, satellite-based positioning in RTK modes, manned aerial photography, and aiborne laser scanning (ALS). The potential for using UAVs in the oil and gas industry today is truly enormous. Numerous safety and reliability problems, which traditionally have been cost consuming for oil and gas companies, can be effectively addressed using UAVs. The study included processing of data obtained from the unmanned complex in three modern software packages (Agisoft Photoscan Professional, v 1.2.5.2594 (Russia), ERDAS IMAGINE, v 2015 (USA) and Pix4Dmapper Pro (Switzerland)) of various automation degrees; assessment of accuracy in ArcMap software by superimposing a topographic plan on an orthomosaic with a scale of 1: 500 on the territory under consideration; calculation of economic and labor costs. As part of the study, it was proved that the use of UAVs was possible not only for the geodetic work, but also for solving other equally important tasks of the oil and gas industry, which leads to a decrease in economic and environmental risks, automation of processes related to monitoring of oil facilities, prevention of illegal attempts of pipeline tie-ins, oil spills. In addition, based on the obtained orthophotomaps, the economic, accuracy and labor-time feasibility of using unmanned systems were confirmed. It has been established that the use of unmanned aerial vehicles in various fields of oil and gas activities for solving engineering and geodetic problems is an integral part of any company engaged in the production and transportation of hydrocarbons.

This article offers a comparative analysis of the emergence of CO2 capture and storage (CCS) activities and strategies in three multinational oil and gas companies. Exxon/ExxonMobil was first to make plans for a major, pioneering CCS project, but later pursued a relatively cautious strategy. In contrast, BP showed little interest in CCS up until 1997, but from that point on developed a particularly ambitious strategy. Statoil, meanwhile, has been relatively strongly involved in CCS activities for a long time. An explanatory framework with potential for wider application is developed, highlighting how the overall compatibility of CCS with oil and gas industry characteristics created a strategic dilemma for the companies. In explaining their responses, the article emphasizes the process towards institutionalization of CCS as a widely recognized mitigation option, and the three companies' different climate change strategies.

Progress of the global energy industry as well as resources of natural gas of Russia were indicated in this article. The main region of their development over the years is Western Siberia, where more than 80% of gas reserves are explored. It is from here that the main stream of Russian gas flows to countries in Eastern and Western Europe. To date, good prospects have been opened for the preparation of gas reserves and production in eastern Russia with the launch of the Power of Siberia gas pipeline, which determined the high importance of this region, which is of strategic interest to the gas industry in Russia. The main resources of natural gas will be located in remote from the existing gas transmission system, inaccessible areas and areas with a harsh climate, where there are no large markets for the consumption of hydrocarbons. In connection with this, the search is underway for the transportation of natural gas, alternative to pipeline transportation, to the places of consumption. Three possible options are considered. According to the “General scheme for the development of the gas industry for the period up to 2030” , one of the promising options for the development of gas processing industries is the development and implementation of efficient technologies for the production of synthetic liquid fuels (GTL technology) aimed at solving the problems of developing small, mature and hard-to-reach natural gas fields. The special emphasize was made on one of the promising variants of gas-processing productions development - development and implementation of GTL (Gas to liquid) technology as a new method of production of synthetic liquid hydrocarbons from natural gas. Relevance, possible advantages, and prospects of GTL technology were also mentioned. The example of the Republic of Sakha (Yakutia) shown the possibility of using GTL technology, using as a raw material of natural gas of the Middle-Vilyusk gas condensate (gk) field. Also shown in this article are experimental details of the study of an individual hydrocarbon gas composition, which was determined using the gas chromatography method. The conclusion was made on the Republic's Oil and Gas Complex's overall potential cost-benefit in case of GTL technology implementation.

Oil and gas infrastructure is vast and diverse, occupying an integral position in the global economy. Without such infrastructure, the majority of fuel needed to light, heat, and cool homes and businesses and to power transportation and industry cannot be produced and delivered to markets and consumers. In this sense, infrastructure is the lifeblood of the oil and gas industry. Oil and gas infrastructure encompasses a myriad of assets, including pipelines, drilling platforms, refineries, terminals, processing plants, and storage facilities, most of which are massive and expensive industrial complexes found in all corners of the world. Such assets can yield significant economic benefits, but they also present numerous challenges, not the least of which are operational, environmental, and political in nature.
