The present study describes insufficient efficiency of granular polymer and non-woven fibrous sorbents, as well as polysaccharide microgel suspension in the context of elimination of man-made oil spills to soil and water in Arctic conditions. Feasibility of using gelling polymer coatings based on linear polymers ("liquid" sorbents) is carried out; they are at the stage of experimental production. They are soluble in oil products and their non-polar derivatives. Results on dispersant efficiency and stability in seawater are given. Mechanism of affecting of gelling polymer coating on oil and oil products is described. It should be noted that dissolution phases of a polymer covering happen successively. Coagulation of polymer particles connected by intermolecular interaction leads to formation of continuous hydrogel. The hydrogel possesses elasticity and stability when subjected to oil or oil products emulsified in seawater. Therefore there is a formation of a continuous gel-like polymer film. Detailed laboratory testing found that the time of oil thickening during localization of a man-made spill using gelling polymer coatings depends on sea water and air temperature, the presence of wind, and oil concentration in the water.

 

Keywords: granular polymer sorbents; non-woven fibrous sorbents and materials; dispersants; seawater; gelling polymer coatings; polysaccharides; biologically active composition; "liquid" sorbents.

The results of studies on the production of geo-environmentally friendly products based on drill cuttings selected from fields in the Western Siberia are presented. It has been established that the physical and chemical values of drill cuttings depend on a drilling fluid composition. The possibility of obtaining technical soil based on the drill cuttings is determined. A new technique of getting re-cultivated soil is developed. The effectiveness of the obtained material use for biological reclamation was determined by sowing grass mixtures consisting of various plant species. The controlled indicators defined for man-made soil comply with the requirements for the finished product presented in TU 0391-001-66938274-2014. According to the physical and mechanical properties, the techno-ground samples are characterized by sufficient strength and belong to the M20 brand. This is evidenced by the value of the compressive strength limit of Rñæ = 3,99 MPa.

 

Keywords: drill cuttings; negative impact; environment; disposal; reclamated soil; techno-ground.

In the article the critical analysis of known technologies of oil deactivation in soils was carried out. Reagent encapsulation (TPC) techniques using emulsifiers and various chemical compounds have been shown to be most suitable. In wet soil, they enter ion exchange reactions to form water-insoluble crystallization centers around which the growth and formation of a strong skeleton of capsules take place, inside which oil-contaminated soil particles are involved. Compositions of reagents which form hydroxides and oxides of aluminium, iron (II) and (III), silicon, phosphates, silicates and calcium sulfates are found to be optimal for formation of capsules providing hydrophilic and neutral soil. It is shown that the introduction of an emulsifier into the soil allows reducing the consumption of reagents and strengthening the capsules. As a result of encapsulation, dry, loose, light brown soils with minimal toxicity are formed, where oil is deactivated and does not pose harmful effects to the environment.

 

Keywords: oil slimes; reagent encapsulation technology; oil emulsifiers; water extracts of oil slurries; their toxicity and oxidability; bio-testing.

The study of the fatigue characteristics of repaired welded joints is an important task to determine their remaining lifetime. At present, there is no methodology that allows calculating the resource of reconditioned welded joints; therefore, industrial safety experts use the diagrams and fatigue equations given in the normative documentation for new joints when extending the resource. It is also not established whether there is a difference in fatigue characteristics depending on the type of pipe joint “T” or “K”. In this regard, the authors conducted research during which a new welded joint was brought to primary failure, and then repaired and brought to repeated failure. Based on these experiments, graphs were constructed that describe the dependence of the number of cycles on the values of the amplitudes of the alternating stresses and a mathematical equation was obtained that describes the fatigue parameters for both "T" and "K" types of welded joints.

 

Keówords: offshore stationary platform; fatigue; reconditioned welded joints; “T” and “K” types of welded joints.

The characteristics of soils and their structure, composing the upper part of the geological environment, as well as the characteristics of permafrost processes in the coastal zone of the Pechora Sea are presented. The factors of the geological environment stability to industrial (man-made) impacts are considered. The degree of cryogenic processes manifestation with the stability zones allocation is analyzed. The territory zoning according to the degree of the soil’s depositing properties manifestation, depending on the maximum oil intensity and humidity of the constituent substrate, is presented. The analysis made it possible to identify key factors that ensure the stability of the upper part of the geological environment in the coastal zone of the Pechora Sea during the development of hydrocarbons deposits in the north of the Timan-Pechora oil and gas region.

 

Keywords: Pechora’s sea coastal zone; oil fields; stability of the geological environment; permafrost; soil conditions; rock composition; oil and gas facilities.

The purpose of this work is to study the seismic tension of the fault-block structures of the oil and gas province under the influence of surface loads. The object of study is a seismic generating fault-block structure modeled by two semi-bounded plates or layers with parallel boundaries, removed from each other at a certain distance, on the deformable base. Numerical and analytical methods for studying such block structures are proposed. Conclusions are made about the presence and level of tension depending on the geometric and mechanical characteristics of the plates. The presented results can be useful for oil and gas enterprises for the preventive development and implementation of scenarios of directed impact on the seismic generating fault-block structure, for example, with heavy vibrators, in order to reduce seismic tension in the zone of industrial production of hydrocarbon raw materials in areas of high seismicity, and to intensify oil production.

 

Keywords: oil and gas province; seismic generating structure; block structure; seismic tension; modeling.

The paper considers the scheme of drilling waste disposal, generated during construction of production gas wells in the Arctic zone in the Russian Federation at the Kharasaveysky gas condensate field developed in compliance with the unique climatic and geo-cryological conditions in the absence of transportation and specialized infrastructure. The applied project solutions afford not only reduction and/or elimination of the negative impact of drilling wastes on the environment but also decrease the natural resources consumption and optimize material and energy costs.

Disposal of drilling waste for the companies of the oil producing industry is an urgent problem. It is associated with the need to develop advanced environmentally friendly methods for the disposal of drilling wastes, with the receipt of material that does not have a negative impact on the environment. The paper presents a method of drill cuttings utilization, which consists in introducing a mixture of components that improves the water-physical and chemical properties of the obtained material. The introduction of natural mineral sorbents in the drill cuttings helped to reduce the concentration of petroleum products to 1100 mg/kg. The content of heavy metals in gross form (manganese, copper, zinc, lead) in drill cuttings and inert material were at the level of clarke contents in the lithosphere and did not exceed the estimated allowable concentrations (EAC). According to the granulometric composition, inert materials belonged to loose sands. The tested aqueous extracts made of inert material have an acute toxic effect on test-objects (cladocera Crustacea Daphnia magna Straus and unicellular green algae Chlorella vulgaris Beijer), the dilution ratio was up to 2,70 times.

 

Keywords: drill cuttings; disposal; inert material; natural mineral sorbents; toxicity.
