» Telemetric monitoring of operation regimes of the wells of the Kharvutinsk Area of the Yamburg Gas Field in conditions of sand andliquid recovery with the use of DSP-А alarm sensors

For a number of years Gazprom, PJSC has been working on the technological development of the industry and the product and technology import phase-out. The actions include the identification of needs for this products and technologies at different industry-based facilities, research and developments in the field of creating substitutions, production of commercial prototypes, their batch production at national enterprises. The efficiency of the performed work is evidenced by the fact that the number of positions in the list of products imported by Gazprom, PJSC decreased by 48 % for 2016. In such a case, the import phase-out actions primarily take into account such strategically important activities for the company as condensed natural gas production and hydrocarbon recovery at continental shelf fields. The article presents some examples of developments of national companies which are establishing or have already established the output of import phase-out products for Gazprom , PJSC’s needs. The article also considers state support measures that contribute to a more efficient work of enterprises in developing and producing products that replace imported analogues.

Keywords: GAZPROM”, PJSC’S PRODUCTION FACILITIES, LONG-TERM AND MID-TERM IMPORT PHASE-OUT PROGRAMS, IMPORT PHASE-OUT PRODUCTS, IMPORT PHASE-OUT TECHNOLOGIES, PRODUCTS AND TECHNOLOGIES THAT ARE CRITICAL TO REPRODUCTION AT PRESENT, STATE SUPPORT MEASURES.

SHELF DEVELOPMENT

» Increasing the strength of soft grounds when developing water oil and gas field structures and facilities of the coastline infrastructure at the far East Shelf

Arrangement and development of oil and gas fields at the Far East shelf are carried out in extremely difficult natural and climatic, engineering and geological conditions. The conditions impose special requirements to the design and construction of development targets. The article presents the current state of soil engineering amelioration in the light of the tasks in hand. The article considers a deep soil mixing technology (DSM) which is used to strengthen soft soils when designing and constructing water oil and gas field structures and facilities of the coastline infrastructure. The most topical and critical issue for using the DSM technology lies in decreasing the cement consumption (with cement being the main bounding agent), at the same time preserving the quality of “strengthened” soils. To achieve this goal, the authors propose to use additives from synthetic zeolites which are basically recycled absorbent production and use waste. The proposal is supported by the results of laboratory research carried out by the authors.

» Multiple-factor assessment system of hydrocarbon fields at the russian shelf

The article is dedicated to the implementation of a new classification of hydrocarbon field reserves since January 1, 2016. By analyzing its applicability to the shelf fields, the authors arrive at a conclusion that in its current state it is of little use for such targets. Nevertheless, the specified fields require a fair assessment, and, as an addition or alternative to the classification, the authors propose their original rating system project draft which takes into account the full range of factors: from the geological structure, state of knowledge and possible recovery parameters at shelf fields to engineering and economic characteristics of their development. The proposed system can be successfully implemented in ground fields as well. In the beginning it can be used for in-house assessment of exploration and development targets, and then, if positive results are achieved, this system can include the new classification which currently cannot take into account the parameters of economic attractiveness of the majority of shelf fields and the presence of new recovery technologies.

Keywords: reserves classification, oil, gas, shelf fields, oil and gas exploration, reserves rating.

OCCUPATIONAL AND INDUSTRIAL SAFETY

» Improving the safety of flow processes by professional risk management at the oil-and-gas production enterprises in the Аrctic

Over 85 per cent of oil and gas resources of the Russian shelf are concentrated in the Arctic seas. As a result, it is high time and relevant to talk about oil and gas recovery in extreme conditions of the Arctic shelf. Fields development of the Arctic region is going on in extremely adverse climatic and geotechnical conditions, such as a disturbance of photoperiodicity during polar day and polar night, an altered geomagnetic activity, increased non-ionizing cosmic rays, sharp fluctuations in atmospheric pressure, a reduction of partial oxygen pressure, a polar tension syndrome, etc. Considering the above conditions, likelihood of accidents, injuries and occupational diseases of the staff is greater. In these circumstances, in order to ensure safety in the workplace, it is necessary to assess and manage occupational risks on the basis of a systematic analysis of the possible causes of occupational diseases and accidents at work, to forecast their consequences and make adequate technical and organizational decisions. Annual aggregate damage to property caused by industrial accidents, costs of liquidation of accidents and their consequences in the Russian Federation amount to tens of billions rubles. A significant share of these costs is associated with accidents at hazardous production facilities. Thus, assessment and management of occupational risks on the Arctic shelf is a priority. The author in his article considers basic provisions of the theory of occupational risk, provides an overview of current qualitative and quantitative methods of risk assessment, their advantages and disadvantages, some results of the assessment of occupational risks at marine structures on the Arctic shelf and some recommendations for the management of occupational risks taking into account the specific offshore working conditions.

Keywords: THE ARCTIC SHELF, EXTREME WORKING CONDITIONS, DANGEROUS AND HARMFUL FACTORS, OCCUPATIONAL RISKS, METHODS OF QUALITATIVE AND QUANTITATIVE RISK ASSESSMENT, RISK MANAGEMENT.
