One of the significant sources of the increase in reserves and oil production at the present stage are deposits of super-viscous oils (natural bitumen), the geological resources of which in the Republic of Tatarstan range from 1.5 to 7 billion. The fields of super-viscous oils have their own characteristics: small depths and sizes, oils have high density and viscosity.

Every year, as the oil industry develops, the technological impact on the environment and the geological environment is intensifying.

In the second half of the last century, the first symptoms appeared, indicating the alarming consequences of intensive mining.

In this paper, possible methods for the prevention and disposal of waste sediments of asphaltene, resin and paraffin substances (ARP-S) are systematized. The practical importance of the rational use of the existing methods for prevention of ARP-S sediments occurrence, as well as the recycling methods are represented. The practical significance is considered based on the examples of Russian and foreign enterprises. The formation of ARP-S sediments is possible during wells drilling, as well as during operation, well workover and cleaning of drainage tanks. This type of waste is mostly paraffinic, thats why mechanical method of prevention (pipeline scraper) is adopted. This paper summarizes the existing technologies for recycling and processing of sludges using them as alternative energy sources. The problem of their utilization is now solved by processing in the existing scheme for the preparation of commercial oil. Full utilization of liquid petroleum wastes, even at a single enterprise, provides a reduction in the total amount of petroleum wastes by more than 70% and the return of marketable oil to resource turnover. The paper presents the results of calculations of wastes generation during oilfield construction and operation. Hazardous wastes were considered as environmentally dangerous according to classification. Promising areas of ARP-S sediments processing are presented.

The analysis of the time series of quarterly volumes of flaring of associated petroleum gas (APG) in the Khanty-Mansi Autonomous Area (KhMAA) for the period of 2012-2016 was carried out. It is established that the trend of reducing the volume of combustible gas for a specified period is described by an exponential equation. It is shown that, along with the exponential trend, cyclical seasonal variations in the volume of the combusted gas are observed. A model is proposed for predicting the volume of gas being combusted as a sum of two terms, the first of which is represented by the equation of the exponential trend, and the second term is intended to take into account seasonal fluctuations in gas flaring volumes. An example of a forecast of APG flaring volumes for the period 2017-2020 is given for the territory of the KhMAA.

Efficient utilization technology of petroleum gas at oil separation last stage

Ilmer Yu. Khasanov, Boris S. Zhirnov, Ural R. Ilyasov, Vladimir I. Rogozin

It is proposed a new process and equipment for gas/vapor recovery at last stage of oil separation to obtain commercial product - broad fraction of light hydrocarbons (NGL) - directly at oil fields. The process is based on compression of low pressure gas and "hot" separation of condensate in a multipurpose separator developed by the authors. The method is available for recovering of combination gases and in gas industry in a late stage of gas production at specific hydrocarbon deposits.

Polycyclic aromatic hydrocarbons as a geochemical markers for oil pollution of the environment

Alexandr P. Khaustov, Margarita M. Redina

Justify the role of polycyclic aromatic hydrocarbons (PAH) as a geochemical marker of the environment pollution. Considered the possibilities of use of the indicator ratios based on the PAHs concentrations in the environmental and technogenic objects for the identification of the genesis of the pollution. On the example of 24 cases (crude oil from different regions of the world, oil slimes and oil reservoir sediments) estimated theefficiency of different diagnostic ratios and their adequacy for the conditions of Russia. Shown the possibility of identification of the genesis of oil pollution using multivariate statistical methods.
