Opis:: This paper presents new achievements in the field of designing the gravitation and gravitation-underpressure chamber for bottom flushing in the detention chamber immediately after its emptying from the accumulated sewage. Temporary accumulation of the sewage in the detention chamber of the reservoir causes partial sedimentation of the solids suspended in the liquid. The location of the flushing chamber at the maximal level of filling with sewage in the retention chamber substantially improves the effectiveness of flushing of the bottom of the retention chamber with the stream of sewage that is discharged from the flushing chamber. An opportunity for effective flushing of the sludge that remains on the bottom of a detention chamber represents an important operation which is essential for reliable functioning of retention reservoirs within sewerage systems.

nonconventional gas reservoirs
Opis:: The installation to the collection and transport of gas in case of the evil conventional occupies a great many places. When we are meeting variable factors in time e.g. with the efficiency this we are in a position to propose installations smaller and divided into modules which in case of the reduction of the quantity of extracted gas would be able to to be deducted in the easy way or augmented of the existing installation. Economic aspects engaged searches of more effective installations to the cleaning and the drainage of gas. Already from the early 90s of the 20th century, the oil industry sacrificed many attention to methods of the separation. This permitted the discovery of such separators as Gas/Liquid Cylindrical-Cyclone (GLCC). In comparison with conventional, compact separators are easy in the installation and the service, require the small maintenance. The simplicity of the construction, smaller measurements and the balance GLCC provides savings of costs. In the paper authors will review solutions of compact separators and also the preliminary adaptation and the definition of measurements for given parameters of technological exploited of natural gas reservoirs.

Tematy:: nature gas reservoirs
workover operations
Opis:: At the same time with gas reservoirs energetic depletion there appears the perforation deterioration or blockage issue. Mostly, in the mature gas reservoirs, a big attention must be given to well interventions for maintaining or increasing the production. Because of the workover operation risks and costs, the oil companies prefer as much as possible rigless jobs to accomplish well stimulation like reperforation or several coil tubing operations (acidizing, fracturing etc). In our rehabilitation programs for many gas reservoirs, our company accomplished successfully more stimulation jobs. In this paper, we will present some case studies and results obtained after several rigless operations which assure long term production increases.

Tytuł:: Non-damaging flow below the Mietków reservoir on the Bystrzyca river

Tematy:: reservoirs
non-damaging flow
flood
Opis:: Non-damaging flow below storage reservoirs is one of the key factors which affect proper water management, especially the protection of valleys against flooding. Following analysis of river flow capacities below reservoirs it should be noted that, over the years, these capacities are subject to significant limitations. This is usually caused by inappropriate floodplain management. Buildings are often built closer to the river channels, which in consequence causes flooding of the buildings at low flood discharges. Repeated inundations and thus increasing losses oblige the local authorities to maintain low outflows from reservoirs in the first phase of the freshet, which leads to a rapid fulfillment of flood reserves of the reservoirs. Then, the culmination of flood wave often takes place when the reservoirs are filled and consequently high discharges from the reservoirs must be realized. This causes flooding of the areas and buildings below the storage reservoirs. This situation could have been avoided if the riverbeds and floodplains had been adjusted to pass non-damaging flow and adopted it as the basis for the water management of a given reservoir. A significant improvement in reduced reservoir capacities will occur if the values of non-damaging flow below the reservoirs are increased and the losses caused by flood flow are significantly reduced by appropriate spatial development of the areas below the storage reservoirs. The current non-damaging flow below the Mietków reservoir is a striking example of the issue. Three farms located within the floodplain of the Bystrzyca river have an adverse impact on water management of the reservoir when floods take place.

Opis:: The article concerns the self-purification of running waters in areas where they flow into water bodies. At such places, delta forms (alluvial fans, deltas) are created that are built up of the material accumulated by the watercourse. The study was conducted in the Upper Silesia region in southern Poland and concerned delta forms created in seven water bodies (Dzierżno Duże, Dzierżno Małe, Pogoria I, Pogoria III, Przeczyce, Kozłowa Góra, Pławniowice). The choice of the Upper Silesia region as the study area was dictated by the specific process whereby delta forms are created. In this region, which is among the most urbanised and industrialised in Poland, which results in most polluted surface waters. Running waters are heavily burdened with wastewater, by-products from processing minerals (particularly coal dust), technological water, sewage sludge, fertilisers, etc. The deposition of pollutants in river mouths leads to the rapid creation of delta forms with areas ranging from several hundred square metres to around 1 sq. km. The largest delta form has been created at the place where the Kłodnica River enters the Dzierżno Duże reservoir. During low water its area exceeds 1 sq. km and its thickness exceeds ten metres in some places. The overall volume of the Kłodnica River delta is estimated to be slightly over 2 million cu. m. Owing to the deposition that is taking place, running waters are subject to self-purification, particularly with respect to the solid particles they carry. This is a mechanical purification process. Apart from mineral substances, a significant amount of organic matter transported by the river is also deposited. The composition of delta sediments only partly reflects the characteristics of the substrate present in the catchments of the rivers that form the deltas in question, and the deposits often exhibit anthropogenic features. Delta sediments are a material that includes a large amount of organic matter, nutritional substances (mainly phosphorus compounds) and trace elements, including heavy metals. Concentrations of many elements exceed the levels characteristic of the natural geochemical background of sedimentary rocks. Therefore pollutants are immobilised, at least temporarily, during the process of creating the delta form, which protects the quality of the water in the water bodies. This purification effect is amplified by the vegetation overgrowing the deltas, which is dominated by common reed. This vegetation serves as a biological filter for waters that filter through it or remain stagnant, removing many pollutants by way of biological assimilation. Apart from their significance for water self-purification, deltas are important from the point of view of reducing the silting up of water bodies. Delta forms perform many functions in the natural environment as well. These include increasing the retention capacity of the surrounding area, shaping new habitats and increasing local biodiversity.

Opis:: The content in this report was presented at the 3rd MUSE steering committee meeting at UoS, in Stavanger, December 10th, 2015. The project report consists of five individual reports, each focusing on various themes: 1. Hydrocarbon Reservoir Behaviour during the Process of Abandonment and Thereafter by Victor Chukwudi Anokwuru, IPT/TN/UoS 2. Monitoring Techniques Applied to CCS-EOR by Intergrity Obara, IPT/TN/UoS 3. Risk Assessment by Emil Gazizullin, IPT/TN/UoS 4. Environmental Considerations of CO2 Projects by Oduro Takyiwa Susanna, IKM/TN UoS and Yen Adams Sokama-Neuyam, IPT/TN/UoS 5. How to Reduce the Likelihood of Environmental Impacts During Plug and Abandonment by Alexander Steine Johnsen, Preben Emil Haugen and Jann Rune Ursin, IPT/TN/UoS The reports are all written under supervision of the WP2 project leader. All reports are based on open sources; local (UoS) reports, publications available on the internet, official publications and journal papers, and communications with a great number of individual resource persons in the Norwegian oil and gas industry. The relevance of the work presented in the above mentioned reports, in relation to the MUSE project objectives is, as far possible, promoted through carefully following the project description (part of the AGH–UoS partnership agreement) and with reference to a preliminary WP1 progress report from mid February 2015; WP1-Selecting reservoirs for application of CO2 storage with IOR technology and feasibility studies. The work in the MUSE project is accomplished through the willingness and skills of UoS department master students, hired as project assistants. Fortunately for the project there are quite a few high class student, capable of writing high quality technical reports at UoS. The five reports are presented sequentially and all reports are the responsibility of the author and all reports are approved by the WP2 project leader.

Opis:: The aim of this study was to assess the mercury concentration in bottom sediments, collected from eight reservoirs located in south-eastern Poland. A DMA-80 Mercury Analyser was used for the analysis of the concentration of mercury in bottom sediments. Concentration of mercury in sediments was between 0.01–0.18 mg∙kg−1. The research results show that 13 samples are above the Polish Hg background level. Only 9 samples are below the background level. Generally, the sediments belonged to class I and II (unpolluted and moderately polluted sediments). The concentration of mercury in bottom sediments follows the order: Rybnik (highest) > Bagna Rzeszowskie > Rzeszów > Ożanna > Brzóza Stadnicka > Brzóza Królewska > Głuchów > Narożniki (lowest). The low mercury content in sediments is related to absent or limited anthropogenic sources of this metal. Elevated concentrations of Hg in bottom sediments of the reservoirs in Rybnik and Bagna Rzeszowskie are related to their proximity to large agglomerations and industrial plants. Organic matter was likely to be the most important factors controlling the concentration and distribution of mercury in the studied sediments.

Opis:: The aim of the paper is to assess the fluctuations of water levels in the Turawa Reservoir (50° 43' N, 18° 08' E) in relation to the tourist use of the water body. The reservoir is situated within the macroregion of the Silesian Lowland in the mesoregion of the Opole Plain. In administrative terms, the reservoir is situated in the pole Province within the borough of Turawa. In hydrological terms, in turn, it is situated in the catchment area of the Mała Panew river, which belongs to the basin of the Odra river. The Turawa Reservoir was opened for use in 1938, and in 1948 it was filled with water to its maximum for the first time. At present, the surface area of the reservoir, when it is filled with water to its maximum, is about 20.8 km2, its volume 99.5 mln m3, and its depth exceeds 13 meters. In the period of hydrological years 1976-2000 water levels in this reservoir were characterized by high, unnoticed in natural conditions, amplitudes of changes reaching 6.99 m. Anthropogenically stimulated fluctuations in the water level result in conflicts in terms of tasks and functions that the Turawa Reservoir was designed for. Changes in the level of the water surface in the Turawa Reservoir resulted from the impact of the natural factors (thaw and rainfall related high water levels), as well as anthropogenic ones (the need to improve sailing conditions, water supply for industrial and municipal needs). Decreasing the fluctuations of water levels in the Turawa Reservoir is necessary in order to maintain its tourist-recreational functions and keep the ecological condition of its waters at the appropriate level.

Opis:: This paper presents the analysis of challenges concerning development of natural gas fields with low- -permeable reservoirs and experimental results of conducted laboratory researches, which provide the opportunity to establish regularities of adsorption-desorption processes in tight sands and develop technologies that enable increasing gas recovery factor from low-permeable reservoirs. For this purpose, a series of laboratory experiments were carried out on the sand packed models of layers with different permeability (from 9.7 to 93 mD) using methane, nitrogen and carbon dioxide. The pressure in the experiments varied from 1 to 10 MPa, temperature – 22–60 degrees of Celsius. These studies revealed the influence of pressure, temperature, reservoir permeability and non-hydrocarbon gases injection rate on the course of adsorption-desorption processes and their impact on the gas recovery factor. The obtained results of conducted experiments show high efficiency of non-hydrocarbon gases injection to enhance gas recovery and feasibility of their application in the natural gas field with low-permeable reservoirs.

Opis:: One of increasingly used methods for reducing carbon dioxide emission to atmosphere is CCS technology (Carbon Capture and Storage). The last element of sequestration technological chain, after capturing and transporting is CO2 storage which is currently considered in natural environment, oceans and geological structures - of which depleted gas reservoirs have high sequestrating potential mainly by virtue of proven record of geological recognition and high recovery factor, hence, great storage capacity. This paper is connected with first stage of CO2 storage in depleted gas reservoir i.e. flow of injected fluid inside the well. Conducted analysis was concerned about CO2 flow conditions inside the injection well in various stages of CO2 storage process, and furthermore, relation between reservoir pressure, injection rate, well diameter. Moreover, the thermodynamic conditions and its impact on changeability of PVT parameters and hence phase changes were also investigated
