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.

The stocks of gas in new deposits of hydrocarbons (which putted into exploration during of last years) are mostly small. Therefore the basic extraction of gas is linked to the baseline fields, such as Shebelinske, West Hrestishchenske, Efremivske, Mashivske, Rospashnivske, and fields with 10-50 billion m3 of initial balance stocks. The most common features of a reservoir engineering at a completing stage of extraction are reduction of operating pressures, a low production rate of wells and unsatisfactory availability index of wells. The basic technological decisions that allow to stabilize gas-producing rates and to enhance gas and condensate efficiency of production facilities, are: reduction of operating pressures on a number of fields for the purpose of accretion of gas recovery rates, changing of depleted production facilities to the upper or bottom ones, boring of new exploitation wells and restoration of liquidated ones, engineering of the side-tracking trunks in a low-rating holes and in the holes of the idle fund.

Applying dynamic reservoir characterization techniques requires integrating the geologic framework of the reservoir, the reservoir processes of manipulating the fluids and pressures within the reservoir and the anticipated seismic response observed over time using surface seismic data. It is useful to gain an appreciation of general seismology in order to relate the seismic measurements to the reservoir under study. In the following sections, we present basic seismic theory, the relation to the reservoir through rock physics, and then increase the complexity of seismic theory to approach a realistic view of the reservoir framework and conditions. Being able to predict, or reservoir processes, the elastic seismic response to a given reservoir state allows us to invert an observed seismic response to the actual reservoir conditions. Repeated measurements over time provide the dynamic aspect of reservoir characterization, allowing prediction of future reservoir performance. In "Multicomponent seismology — part I", we introduce elastic wave propagation, relating the stress and strain of a propagating seismic wave, the stiffness tensor, the wave equation and elastic wave modes in isotropic media. Simple half-space models shows changes in P- and S-wave reflectivity due to changing fluid types in porous sandstone. Generally speaking, many reservoir time-lapse seismic signatures associated with compressibility changes in the bulk rock properties can be modeled using basic, isotropic assumptions. Examples include replacing a compressible fluid with an incompressible fluid such as a reservoir producing high GOR oil with strong water drive or water injection support. A second example would be heavy oil production using steam-assisted gravity drainage. In both of these cases, changes in bulk rock compressibility are the dominant variation over time, observable using P-wave time-lapse seismic data.

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.

This paper reviews an approach to three stage selection of EOR strategies. First the screening model allows for a fast first-order screening of key EOR applicability methods at given reservoir conditions using a multi-criterion model and distribution functions based on applicability ranges for critical reservoir parameters. On a second stage a model for oil recovery factor estimation based on the statistical data from projects carried out worldwide is applied. Finally, analytical methods could be used for quantitative analysis and production profile calculations for a wide range of key oil recovery methods. Analytical methods are limited by simplified representation of the reservoir and EOR processes; however solutions are exact and not affected by the numerical dispersion. A wide range of reservoir parameters and computed results enable the user to perform rapid and comprehensive reservoir analyses as well as sensitivity studies. This tool can be compared with a "compass" helping reservoir and petroleum engineers to identify and successfully implement EOR/IOR methods at their fields.

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.

The paper presents a research covering the stability of phosphorus retention in the bottom sediments, resulting from application of gypsum in anoxic conditions and in slightly acidic environment (pH~5) of solutions. The present work also contains an analysis of possible effects of gypsum application for water from the reservoir, on the basis of selected parameters of overlying water. Undisturbed deposit cores extracted from two research stations on the Solina Reservoir have been a subject to a 10-weeks long exposure in determinate conditions, after application of gypsum. The conducted research indicated that retention capacities of deposits, which become increased after the use of gypsum, will decrease over time (e.g. after winter period). Application of gypsum led to a quite significant increase in concentrations of calcium in solutions. Intense release of iron from the sediments into the solutions and decrease in SO42- content, during the said 10-week exposure in anoxic conditions, indicates the use of iron (III) and sulphates as electron acceptors in process of oxidization of an organic substance.

The report presents the algorithms and software methodology for determining the optimal trajectory of the horizontal well in the reservoir using three-dimensional geological and hydrodynamic model. The implementation and use this methodology allows to determine the optimal zone for efficient formation of horizontal wells in the automated mode, using the results of hydrodynamic modeling. The algorithms involve the conversion of primary data for a given function, and after the conversion, the data is returned to the modeling software for visualization and further use. The software is designed as a stand-alone windows application that does not require installation of additional virtual environments. The utility is based on the Eclipse software data format, which can be considered standard and is compatible with most similar systems.

Building permit decisions are one of the most important elements of the investment process in Poland. It should be noted that water reservoirs influence the diversification of landscapes by increasing their attractiveness in both urban and rural areas. The article aimed to verify the relationship between the changes in land-use development and investments related to small retention. Another goal was classifying objects for which building permits have been obtained and registered. Changes in land-use development associated with the introduction of ponds, which blend in with the landscape, are desirable from the perspective of retaining water resources in urban and rural ecosystems. The research methodology was based on spatial data and included statistical analyses in three regions: Mazowieckie, Lodzkie and Swietokrzyskie. Studies carried out in these regions showed a spatial correlation associated with investments in small retention. The research used methods of the global I Moran statistic and local Moran statistics. The data used in the study came from the Register of Applications, Decisions and Notifications, made available by the Main Office of Construction Site. The research indicates clusters of investments in small retention in analysed regions. The majority of investors are residents who invest in earth ponds. The study shows that investment in small retention is connected with ecosystem services.

W ciągu ostatnich 40 lat, w osadach miocenu zapadliska przedkarpackiego odkryto szereg zasobnych złóż gazu ziemnego. Ich wielomiliardowe zasoby decydowały wówczas w sposób jednoznaczny o opłacalności poszukiwań. Obecnie odkrywane złoża mają zasoby znacznie mniejsze, dlatego też ich opłacalność ekonomiczna jest często kwestionowana. W ramach prac poszukiwawczych, prowadzonych przez BG Geonafta, opracowano oryginalną metodyką określania granicznych wartości zasobów i mocy produkcyjnych odwiertów, przy których planowane inwestycje poszukiwawcze stają się opłacalne ekonomicznie. Podstawą tej metodyki było sporządzenie wielofunkcyjnego modelu zależności kosztów od odkrywanych zasobów oraz określenie wartości granicznych, koniecznych do wykonywania analiz opłacalności ekonomicznej. Metodyka ustalania wartości granicznych zasobów możliwych do odkrycia oraz możliwych do uzyskania mocy produkcyjnych odwiertów (złóż) pozwala na w pełni obiektywną ocenę możliwości odrywania złóż, które będą ekonomicznie opłacalne dla inwestora. Szczegółowe określenie całości kosztów ponoszonych na poszukiwania i zagospodarowanie złóż jest bazą dla wykonywania jakichkolwiek obliczeń opłacalności ekonomicznej. Modele zbudowane dla poszczególnych regionów wschodniej części zapadliska przedkarpackiego pozbawione są ocen subiektywnych i w połączeniu z oszacowaniem prognostycznych, zasobów pozostałych jeszcze w tej części basenu do odkrycia i wydobycia, mogą stać się podstawą do opracowania generalnej strategii poszukiwań w zapadlisku przedkarpackim.

It is common knowledge that the biggest gas reservoirs were already discovered in the area of the Carpathian Foredeep. These sometimes giant, in Polish conditions, gas fields like Przemyśl, were obviously profitable. Today exploration is in the late stage and it is possible to find the numerous smaller gas fields. Their profitable is questionable. That was the reason to perform the special project for methodology of the economical evaluation of the small and medium gas fields. The main point of that project was to determine the minimum recoverable gas reserves and the minimum production of the gas from one well or field to make any exploration profitable. The results of the project in connection with estimation of the remaining gas reserves in the Eastern part of the Carpathian Foredeep can be the base of the future exploration strategy in that area.
