Operational Activities

The paper presents the possibilities of optimizing technological approaches for performing hydraulic fracturing operations, taking into account the transition from traditionally used chemical components of the process fluid to synthetic gelling polymers. The proposed option makes it possible to reduce the unit costs of operational activities to increase oil production both for new assets of oil and gas producing companies and for assets at the stage of industrial development. The special emphasis of the proposed technological solutions is correlated with the environmental Agenda for Sustainable Development until 2030, aimed at transforming the production processes of the energy complex to reduce the ecological footprint of enterprises. A complete set of laboratory studies confirms the prospect of industrial application of synthetic polymer systems and the feasibility of replicating this approach. The subsequent stage of scale-up of pilot tests will allow to have a basis for development and implementation of standards in the oil and gas industry.

Hydraulic Fracture Propagation

AbstractHydraulic fracturing technology is widely used in the oil and gas industry. A part of the technology consists in injecting a mixture of proppant and fluid into the fracture. Proppant significantly increases the viscosity of the injected mixture and can cause plugging of the fracture. In this paper we propose a numerical model of hydraulic fracture propagation within the framework of the radial geometry taking into account the proppant transport and possible plugging. The finite difference method and the singularity subtraction technique near the fracture tip are used in the numerical model. Based on the simulation results it was found that depending on the parameters of the rock, fluid, and fluid injection rate, the plugging can be caused by two reasons. A parameter was introduced to separate these two cases. If this parameter is large enough, then the plugging occurs due to reaching the maximum possible concentration of proppant far from the fracture tip. If its value is small, then the plugging is caused by the proppant reaching a narrow part of the fracture near its tip. The numerical experiments give an estimate of the radius of the filled with proppant part of the fracture for various injection rates and leakages into the rock.

Abstract Cementing operations in deepwater exhibit many challenges worldwide due to shallow flows. Cement sheath integrity and durability play key roles in the oil and gas industry, particularly during drilling and completion stages. Cement sealability serves in maintaining the well integrity by preventing fluid migration to surface and adjacent formations. Failure of cement to seal the annulus can lead to serious dilemmas that may result in loss of well integrity. Gas migration through cemented annulus has been a major issue in the oil and gas industry for decades. Anti-gas migration additives are usually mixed with the cement slurry to combat and prevent gas migration. In fact, these additives enhance and improve the cement sealability, bonding, and serve in preventing microannuli evolution. Cement sealability can be assessed and evaluated by their ability to seal and prevent any leakage through and around the cemented annulus. Few laboratory studies have been conducted to evaluate the sealability of oil well cement. In this study, a setup was built to simulate the gas migration through and around the cement. A series of experiments were conducted on these setups to examine the cement sealability of neat Class H cement and also to evaluate the effect of anti-gas migration additives on the cement sealability. Different additives were used in this setup such as microsilica, fly ash, nanomaterials and latex. Experiments conducted in this work revealed that the cement (without anti-gas migration additive) lack the ability to seal the annulus. Cement slurries prepared with latex improved the cement sealability and mitigated gas migration for a longer time compared to the other slurries. The cement slurry formulated with a commercial additive completely prevented gas migration and proved to be a gas tight. Also, it was found that slurries with short gas transit times have a decent potential to mitigate gas migration, and this depends on the additives used to prepare the cement slurry.

The article analyses experience of foreign countries in import substitution policy in oil and gas industry as an important part of industrial development of national economies and effective use of natural resources on the example of such countries as Brazil, Norway and Great Britain. The considerable role of the state, its ministries and departments is underlined in forming and realization of import substitution policy and consists in the development of regulatory basis, introduction of requirements on localization of production, concessionary financing of enterprises from budget and off-budget sources, development of national standards of product quality, application of special custom regimes and decline in tax rates. Drawn a conclusion about efficiency of oil and gas clusters for the development of national production of goods and services.Identifying features of inside- and out- side-based strategies of import substitution are educed and realized in Brazil and Norway. Taking into account all obtained results, the strategy of mixed-based import substitution is defined as the most acceptable to application in Russian oil and gas industry.Its essence consists in the necessity for industry enterprises to combine strategies of substituting for selective number of import products, that doesn`t have sufficient amount of analogues on the territory of the country, and strategy of creation of new modern import substitution productions that oriented on export where it`s economically reasonable.

Environmental context There is growing worldwide interest in the production of oil and gas from deep, shale formations following advances in the technical expertise to exploit these resources such as hydraulic fracturing (fracking). The potential widespread application of hydraulic fracturing has raised concerns over deleterious environmental impacts on fragile water resources. We discuss the environmental management challenges faced by the oil and gas industry, and the opportunities for innovation in the industry. Abstract The need for cheap and readily available energy and chemical feedstock, and the desire for energy independence have spurred worldwide interest in the development of unconventional oil and gas resources; in particular, the production of oil and gas from shale formations. Although these resources have been known for a long time, the technical expertise and market forces that enable economical development has coincided over the last 15 years. The amalgamation of horizontal drilling and hydraulic fracturing have enabled favourable economics for development of fossil energy from these unconventional reservoirs, but their potential widespread application has raised concerns over deleterious environmental impacts on fragile water resources. The environmental management challenges faced by the oil and gas industry arise from local water availability and infrastructure for treating and disposing of the high-strength wastewater that is produced. Although there are significant challenges, these create opportunities for innovation in the industry.

Increasing Demand

As the “anti-frack” movement gains momentum in society and the media, the oil and gas industry is faced with increasing demand for public participation and consultation in hydraulic fracturing operations. In Alberta, public participation has taken a number of forms, occurring during both the regulatory process and hydraulic fracturing operations themselves. This article analyzes the adequacy of these public participation opportunities by outlining the current opportunities for participation and the Alberta Court of Appeal’s rulings regarding the adequacy of notification and consultation. Ultimately, the article concludes that despite a number of new regulatory initiatives, opportunities for public participation in hydraulic fracturing operations have not increased. However, the article remains optimistic that changes can and should occur, increasing opportunities for public participation and improving the timing and quality of such consultation.
