High Viscosity Oil

The need for high-viscosity oil production in the fields of the Russian Federation is substantiated. The technology of high-viscosity oil production by the thermoshaft method is considered, harmful and hazardous factors at the workplaces of the underground group workers are identified, first of all, the microclimate parameters (increased air temperature of the working area), which effect on the formation of occupational diseases and an increase in the risk of injury to the personnel. The main problems associated with the imperfection of the technology of the thermoshaft method for the extraction of high-viscosity oil, which effect on the safety of conducting operations for the extraction of heavy oil, are investigated, and presented. The options of opening up a high-viscosity oil field with a modular mine, which allows to normalize the thermal regime in mine workings, improve working conditions of the oil miners, reduce the level of occupational diseases and injury rate, reduce the volume of work and the costs of mining operations and maintenance of the mine workings, are considered. The system for the development of the Yaregskoye field of high-viscosity oil with the division of the mine field into separate production blocks using a sectional ventilation scheme, which provides for independent ventilation of each module due to the construction of an air supply and air exhaust shafts in each block-module of the mine is proposed in the article. The surface and underground complex of shafts for the construction of a modular mine is presented. The calculation is carried out and the results of technical solutions for airing various modifications of mini — mines are given. The drilling gallery was designed, which is typical for all the options of opening. In the designed modular mines, a closed oil gathering system is proposed. Comparative economic analysis showed the efficiency of the development of new areas of the Yaregskoye high-viscosity oil field using the construction of modular mines.

The results of a pilot application of a chemical composition for enhanced oil recovery developed at the IPC SB RAS are presented. The EOR-composition was tested in 2014 at the Permian-Carboniferous heavy oil deposit at the Usinskoye oil field. It is very effective for an increase in oil production rate and decrease in water cuttings of well production. In terms of the additionally produced oil, the resulting effect is up to 800 tons per well and its duration is up to 6 months. The application of technologies of low-productivity-well stimulation using the oil-displacing IKhNPRO system with controlled viscosity and alkalinity is thought to be promising. This composition is proposed for the cold’ stimulation of high-viscosity oil production as an alternative to thermal methods.

The article addresses viscous and high-viscosity oil production methods that are also relevant to Tazovskoye oil-gas condensate field. Heat-affected zones have been identified to assure the most effective development of the viscous and high-viscosity oil field. Study and patent research results have been used to determine four most effective thermal methods of high-viscosity oil rheological properties con-trol: local heating, co-current heating, local stage heating, and local co-current heating. Existing thermal systems for the implementation of these thermal methods have been analyzed and electrothermal systems based on induction technology have been chosen. The efficiency of induction technology is due to a high range of the thermal flow formed and implementation of two modes: temperature maintenance and emergency heating. Local heating may be ensured by an induction downhole heater of the face area or an induction electric steam generator for the thermal action not only on the face area, but the entire producing formation. A heating device has been proposed based on results of the patent research of induction heating systems for high-viscosity oil. A versatile magnet-operated component has been proposed as a heating body of the induction heating system.

The article analyzes the organizational structure of the project management development with regard to the field of traditional oil reserves, functional responsibilities and areas of responsibility of its participants, as well as the mechanisms of their interaction during the implementation of work to form the organizational structure of managing a large and unique project – the development of high-viscosity oil deposits. It has been revealed that in modern business conditions the implementation of projects for the development and recovery of high-viscosity oil fields based on the traditional organizational structure of management is not effective enough. The main reasons that impede the successful implementation of projects for the development of new deposits based on the traditional organizational structure of management are identified. A new organizational structure for managing a field development project is proposed, which includes a single center of responsibility for the field development project. By the example of the Ashalchinskoye field, the economic effect of using the formed organizational structure for managing the project for developing the field in the form of a possible additional annual oil production was calculated.

The paper presents the results of hygienic assessment of the working environment and work process factors at surface and underground ore mining operations, ferrous metallurgy plants and aluminum production facilities. It has been established that workers are affected by a complex of production factors (dust, toxic substances, noise, vibration, unfavorable micro climate, etc.), the level of which often exceeds the hygienic standards. The workplace conditions of the primary jobs at these enterprises in 60-80% of cases are classified as hazardous, i.e. Class 3 of various hazard degrees. The incidence of occupational diseases remains high, especially in underground mining and at aluminum production plants. The specific features of mining and metallurgical operations and the severity of unfavorable production factors determine the structure of occupational morbidity. Occupational respiratory diseases are most common among workers in the ferrous metallurgy industry and account for 70.3% in total. Vibration-induced pathologies are most frequently diagnosed among excavator, bulldozer and dump truck operators, and account for 52.9% of all the diagnosed occupational diseases. Hearing organ pathology in the form of neurosensory loss of hearing among workers of mining and metallurgical enterprises ranges from 10.2% (aluminum smelters) to 22.7% (ferrous metallurgy plants) in the occupational morbidity structure. Chronic intoxication with fluorine compounds at aluminum smelters was diagnosed in 68.1% of cases. The results obtained confirm the pressing need to improve the working conditions, introduce preventive measures based on the primary prevention principles, and reduce the risk factors of health problems among the workers.

The importance of biotechnology in various areas of human activity has become increasingly obvious in recent years. This determines the interest that, in our opinion, this book represents. It is aimed primarily at specialists engaged in the development of biotechnologies, as well as oil practitioners. The purpose of this book is to give the most complete, in — depth understanding of what oil production biotechnology is. However, it would be frivolous to say that this book exhaustively covers this topic. It is intended to arouse the interest of researchers and practitioners to this problem and give a General idea about it. This is essentially only the basis of some of the main research areas that can be attributed to the field of oil production biotechnologies, as well as an assessment of the principles that are the basis for the development of such technologies. At the same time, we believe that this book can be a good introduction to most of the main problems of oil production biotechnology. The book is intended not only for oil practitioners and specialists in the field of microbial biotechnologies, but also for a wide range of readers. It will be very useful for a student, an engineer specializing in the field of biotechnology of oil field development, as well as scientists to read this book.
