Abstract Hydraulic fracturing is a well stimulation treatment that has been around since the 1940s, becoming more popular in recent years because of the unconventional hydraulic fracturing boom in North America. Between the 1990s and 2000s, the oil and gas industry found an effective way to extract hydrocarbons from formations that were previously uneconomical to produce. Consolidated unconventional formations such as shale and other tight rocks can now be artificially fractured to induce connectivity among the pores containing hydrocarbons, enabling them to easily flow into the wellbore for recovery at the surface. The method of fracturing unconventional reservoirs requires a large amount of surface equipment, continuously working to stimulate the multiple stages perforated along the horizontal section of the shale formation. The operations normally happen on a single or multi-wells pad with several sets of perforations fractured by using the zipper-fracturing methodology (Sierra & Mayerhofer, 2014). Compared with conventional hydraulic fracturing, the surface equipment must perform for extended pump time periods with only short stops for maintenance and replacement of damaged components. This paper addresses improvements made to the fracturing fluid delivery systems as an alternative to the fracturing iron traditionally used in fracture stimulation services. The improvement aims to enhance equipment reliability and simplify surface setup while reducing surface friction pressure during the hydraulic fracturing treatment.

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.

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.

Even though no oil and only a small quantity of natural gas is produced in Oregon, the Oregon Legislature enacted bans in 2019 on hydraulic fracturing until 2025 and on using Oregon’s territorial sea for oil and gas activities. Beyond that legislation, though, legal developments in Oregon this year concerning the oil and gas industry focused on downstream issues.

Sovereign Pipe (formally Halliflow™), a Reinforced Thermoplastic Pipe has been developed by Halliburton Wellstream as an alternative pipeline technology for onshore infield flowlines. This technology builds on Wellstream’s strengths in the provision of unbonded flexible pipe solutions for the offshore oil and gas industry since 1989. A significant proportion of global production originates from onshore developments, and this sector has become increasingly concerned with optimizing production output and maximizing the productive life of fields. This requires the flexibility to manage fields and associated wells efficiently and life cycle costs effectively. Reinforced Thermoplastic Pipe technology is ideally suited to meet this need, providing a robust product that can operate efficiently in extremes of temperature, for extreme services that have corrosion implications for traditional carbon steel pipes and yet provides the flexibility for re-deployment as field conditions change over the product life. This paper details the Sovereign Pipe design methodology, service criteria, Arctic and tundra applications and associated thermal dynamics which make this product suitable for such life of field applications. Factors specifically considered here include ease of manufacturing and installation, and technical characteristics such as thermal dynamics, chemical resistance to internal fluids and resistance to ultra violet degradation.

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.

Measured Time

To meet the requirements of Federal Law № 123-FZ dated July 22, 2008 «Technical Regulations on fire safety requirements», it is required to determine the estimated time of people evacuation and rescue from the hazardous production facility. To solve this problem, an experimental study of the processes of people evacuation and rescue from the structure of the real gas processing plant was conducted. Evacuation and rescue were carried out from the sections of the pipe rack most remote from the exits from it. The ways for the evacuation and rescue included both horizontal parts and stairs. Rescue was carried out using special stretchers, in which there was a dummy imitating an injured person. The time of evacuation and rescue was determined when moving both down and up, which can take place at the enterprises of the oil and gas industry. The time of movement in different sections was determined by the stopwatches. Based on the measured time and the parameters of the sections along which the movement took place, the movement speeds during evacuation and rescue were found. The evacuation experiments involved untrained people, while the rescue experiments involved professional rescuers. The average movement speeds in the evacuation simulation were as follows: down the stair — 100 m/min, up — 44 m/min, along the horizontal section — 193 m/min. The average movement speeds with a victim during the simulation of rescue were the following: down the stair —22 m/min, up —16 m/min, along the horizontal path — 102 m/min.
