Kondash et al. provide a valuable contribution to our understanding of water consumption and wastewater production from oil and gas production using hydraulic fracturing. Unfortunately, their claim that the water intensity of energy production using hydraulic fracturing has increased in all regions is incorrect. More comprehensive data show that, while the water intensity of production may have increased in regions such as the Permian basin, it has decreased by 74% in the Marcellus and by 19% in the Eagle Ford region. This error likely stems from an improper method for estimating energy production from wells: The authors use the median well to represent regional production, which systematically underestimates aggregate production volumes. Across all regions, aggregate data suggest that the water intensity of oil and natural gas production using hydraulic fracturing has increased by 19%. There also appears to be an error in estimates for water consumption in the Permian basin.

Crack Permeability

The analysis of the problem of reducing the permeability of the reservoir wellbore zone during hydraulic fracturing as a result of interaction between carrier of proppant (gel), formation fluids (formation water and hydrocarbons) and mechanical impurities was conducted, the solutions of this problem were presented. The methodical and technological solutions for the well bottomhole treatment with solutions of special compositions (reagents) were given, which with sufficient efficiency contribute to the restoration of the fracture crack permeability. The proposed methodical approach is recommended to use before the massive use of well treatment technologies in order to increase their productivity.

In order to include innovative technologies in clinical recommendations, confirmation of their clinical effectiveness in comprehensive treatment of burned patients is necessary. 1,696 case histories of patients with burns were audited, which are divided into two groups depending on peculiarities of treatment. The use of innovative treatment technologies for burned patients has reduced the incidence of burn disease complications and mortality. Introduction of innovative technologies in treating burned patients into broad clinical practice improves results of provision of specialized, high-tech medical care for victims of burns.

Induced Seismic Activity

High-volume hydraulic fracturing combined with horizontal drilling has “revolutionized” the United States’ oil and gas industry by allowing extraction of previously inaccessible oil and gas trapped in shale rock [1]. Although the United States has extracted shale gas in different states for several decades, the United Kingdom is in the early stages of developing its domestic shale gas resources, in the hopes of replicating the United States’ commercial success with the technologies [2, 3]. However, the extraction of shale gas using hydraulic fracturing and horizontal drilling poses potential risks to the environment and natural resources, human health, and communities and local livelihoods. Risks include contamination of water resources, air pollution, and induced seismic activity near shale gas operation sites. This paper examines the regulation of potential induced seismic activity in Oklahoma, USA, and Lancashire, UK, and concludes with recommendations for strengthening these protections.
