Water for oil pump stations and compressor stations of the main hydrocarbon carriers transmission systems, as well as for most other production facilities of the oil and gas complex is usually supplied from the underground sources. In this case, the function of water intake structures is performed by the bored wells or special wells. As most of them are located in quick ground, they require the use of filters of various designs. In the process of water supply systems operation, wells filters and pre-filter zones of aquifers are contaminated with mechanical particles as well as with the depositions of calcium salt, magnesium salt, silicon salt and other elements dissolved in under-ground waters. It inevitably leads to the increase in hydraulic resistance and, accordingly, to the decrease in wa-ter flow and water intakes productivity. The construction of new buildings requires additional substantial capital investments; therefore it is considered to be economically impracticable and is used very rarely. The more rational way to restore the well flow rate is to clean the filters and the aquifers pre-filter zones off the clogging. It gives a possibility to get a significant economic effect. The analysis of the existing methods and means of water supply wells recovery shows that despite the urgent need to improve water supply and to use groundwater rationally, the search for the most effective methods of regeneration of water take systems is still ongoing. Nowadays, the devel-opment of treatment modes for filters and the prefilter zone of aquifers implies the use of approaches that summa-rize the experience of previous methods which need further theoretical and experimental justification. The authors offer a more effective method for the destruction and dispergation of colmatation deposits. It requires the creation of the vibrational impact inside the filter as well as the creation of a powerful filtration flow of alternating direc-tion by implementing a multi-regulated explosion of the steam-and-gas mixture. It gives an opportunity to use it under a wide range of hydrogeological conditions, as well as in the wells equipped with filters of different types. The suggested method is simple and cost-efficient. In order to find scientifically substantiated criteria for the se-lection of optimal modes of wells treatment using this method, the authors have made a series of research. One of the main purposes of the studies is to determine the nature of the distribution and the parameters of elastic hydro-dynamic oscillations in the aquifer which are caused by the explosion of steam-and-gas mixture in the filter area of the water supply well.

Abstract During the Millennium Drought in Australia, a wide range of supply-side and demand-side water management strategies were adopted in major southeast Australian cities. This study undertakes a time-series quantification (2001–2014) and comparative analysis of the energy use of the urban water supply systems and sewage systems in Melbourne and Sydney before, during and after the drought, and evaluates the energy implications of the drought and the implemented strategies. In addition, the energy implications of residential water use in Melbourne are estimated. The research highlights that large-scale adoption of water conservation strategies can have different impacts on energy use in different parts of the urban water cycle. In Melbourne, the per capita water-related energy use reduction in households related to showering and clothes-washing alone (46% reduction, 580 kWhth/p/yr) was far more substantial than that in the water supply system (32% reduction, 18 kWhth/p/yr). This historical case also demonstrates the importance of balancing supply- and demand-side strategies in managing long-term water security and related energy use. The significant energy saving in water supply systems and households from water conservation can offset the additional energy use from operating energy-intensive supply options such as inter-basin water transfers and seawater desalination during dry years.

Water management systems in industrial facilities, industrial zones, hospitals and other internal water systems relatively frequently fail to meet the intended purpose for which they were built when an extraordinary event occurs. They may even pose a safety hazard. The causes of this condition may be of internal or external origin. Given that internal water supply systems of large premises always have a multipurpose character, i.e. to provide enough drinking water for drinking and sanitation purposes and also as a source of fire water for the fire safety of buildings, they must meet a wide range of hydraulic conditions and technical-operational capabilities. By what means and methods it is possible to achieve the desired state in economically-acceptable dimensions, while maintaining all the necessary hydraulic capabilities of the supply points of drinking and fire water, is briefly described in this article.

Irrigation has contributed significantly to poverty alleviation and food security; however, the sustainability of irrigated agriculture is being questioned both economically and environmentally. Agriculture is the economic sector where most water is consumed, but the lowest price is practised. This article presents an interdisciplinary approach to selecting and prioritizing infrastructure, by differentiating water sources for irrigation, in the case of two complex irrigation systems. Comparative analysis was undertaken for major hydrological, hydraulic, hydrotechnical and economic parameters in order to estimate a long-term water supply for irrigation. In the case of complex irrigation water supply systems, differentiating the ‘subsystems’ per water source and allowing their separate development require less investment and give a better chance for the project implementation. The average calculated investments in basic irrigation infrastructure were in a wide range, from EUR3327 to 10,103 ha−1, depending on anticipated water source (impoundments, groundwater and rivers). Economic water price also varied widely, EUR0.09–0.30 m−3, depending on the water source for irrigation.

Oil And Gas Enterprises

Within the context of energy efficiency and environmental safety, the creation of energy and water supply systems integrated with the units for utilization of combustible waste, low-pressure gases and industrial wastewater are of high priority for oil and gas enterprises. A method for the synthesis of these rational systems and a two-dimensional model for evaluating performance indicators are proposed. We have developed alternative structures based on the block-modular principle of equipment composition formation, which allows structurally parametric integration of energy and utilization modules with technological productions; performed pre-project evaluation of the effectiveness of alternative options for the energy and water supply system with the utilization of low-pressure gases, thermal neutralization of industrial wastewater for methanol recovery plants and designed a multipurpose oil and gas condensate processing enterprise. Integration of utilization, energy and technological installations in energyand water supply systems allows reducing the consumption of heat and electric energy from external sources by 56–100%, and water consumption by 40–50%. Accordingly, the cost of wastewater reducing by an average of 76–93% for oil and gas condensate processing facilities. Almost complete utilization of low-pressure hydrocarbon gases is achieved (the volume of flared emissions is reduced by 90–98%).

Abstract This paper discusses a method for optimizing production facilities design for onshore/offshore wells during new field development. Optimizing the development of new oil and gas fields necessitates the use of accurate predication techniques to minimize uncertainties associated with day-to-day operational challenges related to wells, pipelines and surface facilities. It involves the use of a transient multiphase flow simulator (TMFS) for designing new oil and gas production systems to determine the feasibility of its economic development. A synthetic offshore oil field that covers a wide range of subsurface and surface facility data is considered in this paper. 32 wells and two reservoirs are considered to evaluate the effect of varying sizes of tubing, wellhead choke, flowline, riser, and transport line. A detailed investigation of the scenario of emergency shutdowns to study its effect on the system is performed using TMFS. Other scenarios are also evaluated such as startup, depressurization, pigging, wax deposition, and hydrate formation. This paper provides a method to minimize the cost by selecting the optimum pipelines sizes and diameters, and investigating the requirements of insulation, risk of pipeline corrosions and other related flow assurance parameters. Different facility design scenarios are considered using TMFS tool to achieve operational flexibility and eliminate associated risks. Pressure and temperature conditions are evaluated under several parametric scenarios to determine the best dimensions of the production system. This paper will also provide insight into factors affecting the flow assurance of oil and gas reservoirs.

The Impact

The result of the implementation of technical solutions should be evaluated in terms of the effect on the power system as a whole. At the same time, the main task is to obtain a socio-economic effect noticeable for the consumer of energy resources, as he is a key figure of the energy system. The article considers the influence of modernization of hot water supply systems (HWS) by transferring the function of hot water preparation in apartment buildings to individual heating stations (IHS) from the district heating stations (DHS) with their subsequent liquidation, as well as the elimination of hot water supply grid. The expected result of these measures is the reduction in heat energy loss in heat carrier agents in heating networks, as well as improving the quality and reliability of the hot water supply system and the possible reduction of energy consumption by residents in apartment buildings. The effect on the operation of the heat supply system will not be provided by IHSs themselves, but by automatic controllers, installed together with them. This, in turn, will make it possible for the Central Heating and Power plants (boiler) to be modernized in operation in a timely manner, to improve the system’s efficiency. Computational studies were carried out in order to assess the impact of the transition from IHS to hot water supply on the energy system.

Access to a reliable water supply is central for a well-functioning society. However, water supply systems are subject to a wide range of threats which may affect their ability to provide water to society. This paper presents a novel risk assessment approach that enables thorough analyses of economic losses and associated uncertainties under a range of water supply disruption scenarios. The purpose is to avoid sub-optimization when prioritizing between risk reduction measures, by integrating the full range of possible outcomes from low to high probability events. By combining risk analysis with cost-benefit analysis, additional information is provided on measures for leveraging investments in managing and reducing the risks. This enables the identification of the most economically profitable risk reduction alternatives and enables decision makers to build strategic capacity for operating in difficult and uncertain futures. The presented approach is exemplified on the island of Gotland, one of the most water scarce areas of Sweden.
