CO2-brine-rock interactions as a result of long term experiment onto rock samples from Chabowo anticline, Poland
(Wydawnictwa AGH, 2013) Wdowin, Magdalena; Tarkowski, Radosław; Manecki, Maciej
The presented work concerns investigations of $CO_{2}$-brine-rock interactions conducted over a period of 20-months. Experiments were carried out at laboratory scale with the use of equipment specifically designed for this purpose. Research materials (reservoir and cap rocks) were taken from the Chabowo 3 well located within Chabowo anticline. The experiments were carried out at room temperature (about 25°C) and pressure about 6 MPa. For samples before and after the experiment a numerous investigations were carried out i.e. petrophysical (porosity, surface area, threshold diameter, average capillary, framework and bulk densities) and petrological-mineralogical characteristics. Also brine used for examination before and after experiment was analyzed (chemical analysis). Petrophysical results have shown a significant decrease of porosity (from 17.0% to 7.5%) and surface area (from 0.395 m$^{2}$/g to 0.196 m$^{2}$/g) in case of sandstone. These changes are caused probably by crystallization of halite in pore spaces, because mineralogical analysis (XRD) has shown the presence of halite (3-5% vol. in the rock) after experiment. More detailed results were obtained during mineralogical analyses of thin sections. These results have shown in sandstone samples a small increase of porosity and a small decrease of feldspar and cements (carbonate and clay) as well as matrix which suggests dissolution of these constituents. For clay stone - after experiment XRD clay fraction has shown absence of clay minerals such as montmorillonite, which may also be caused by interaction between the rock, $CO_{2}$ and brine. Dissolution of some minerals is evidenced by chemical analysis of brine where amounts of most tested ions increase after experiment for both sandstone and claystone.

Evaluating capillary threshold pressure in caprocks for carbon storage
(Wydawnictwa AGH, 2024) Soomro, Ahsan Nabi; Anioł, Łukasz
Increased $CO_{2}$ emissions have resulted in extreme climatic variations and as the forecast is that the global temperature will hit its highest-ever level in the next five years. This comes at a time when there is an urgent need for effective and smooth means of reducing greenhouse gas emissions. Geological Sequestration of Carbon (GCS) is a new alternative: the effective and safe storage of $CO_{2}$ underground. The most critical part of the process is the leakage assessment and geological formation safety as a long-term sink of $CO_{2}$. Caprock is important in this process as an efficient long-time sequester for $CO_{2}$, as it is more permeable to $CO_{2}$ than geological reservoirs. Of all the other processes involved in trapping, the most effective in the immediate phase after the injection of $CO_{2}$ is capillary trapping. The $CO_{2}$ remains stored under the caprock until the critical pressure that initiates movement is achieved. Traditional methods, such as mercury intrusion porosimetry and core flooding experiments, do not tend to be replicated correctly in-situ and often complicate the process. Measurements made in such a manner usually overestimate threshold pressures for one of many reasons, be it late flow signal recognition in the low permeability of caprocks or incompletely saturated cores. For these purposes, in-situ-type novel equipment was developed for easy and direct capillary pressure measurement, core saturation, and effortless reproduction of in-situ conditions at higher pressures. This new technique measures the pressure in the outflow directly, so the values of threshold pressure it gives are very exact.

Górnictwo węglowe jako siła napędowa rozwoju zaawansowanych technologii XXI wieku
(2007) Tajduś, Antoni; Dubiński, Józef; Rogut, Jan
Bituminous coal and lignite are the main energy carriers in Poland and according to primary energy consumption forecasts they will remain the basic energy carriers at least until 2030. It goes beyond any question that bituminous coal and lignite form the foundation of energy security in Poland. Currently, the issue of key importance is whether Polish coal mines will be able to meet the required demand or whether coal imports will become necessary. Consequently, the greatest challenge of the Polish mining industry is the cooperation in the field of development of clean coal technologies indispensable in light of the increasingly stricter environmental regulations, especially regarding $CO_{2}$ emissions. This challenge concerns equally the mining as well as the energy sectors. The role of the mining industry as an integrating medium of science and technology, constituting a driving force for the development of advanced twenty first century technologies has been presented. The paper also focuses on the European dimension of new mining and energy technologies which should be developed in Poland to facilitate the country's active participation in international activities in the field of clean coal technologies. Some of which may become Polish specialization. The following exemplary technological solutions which represent different stages of development are discussed in detail: - adsorption enhanced anaerobic coal gasification to hydrogen and/or SNG- Substitute Natural Gas (projects ISCC and C2H). - hydrogen generation by direct underground coal gasification (project HUGE). - $CO_{2}$ recycling in integrated coal and nuclear based energy generation (project proposal). - underground $CO_{2}$ sequestration in unmineable coal seams (project RECOPOL). The proposals of research and development activities which are of key importance to maintain and develop the position of both the mining industry and the coal related energy sector in the 21st century have been delineated.

Montmorillonity podpierane polikationami cyrkonowymi jako sorbenty i katalizatory w ochronie środowiska
(Data obrony: 2014-07-25) Bębenek, Dagna
Wydział Geologii, Geofizyki i Ochrony Środowiska
Modification of sodium montmorillonite with zirconium polycations was carried out. As a result, a microporous, non-swelling, thermally stable structure was obtained. Such material can be used in environmental protection as a catalyst support in the removal of toxic volatile chlorinated organic compounds. The possibility of using Zr-PILC as a kind of storage for carbon dioxide was also examined. Thermal analysis combined with the analysis of the emitted gaseous products showed that this material absorbs certain amount of carbon dioxide. CO2 removal begins at temperatures above 250° C and continues until 800° C. Carbon dioxide binding involved both the outer and the inner surface of Zr-PILC, occurring in different locations, with different intensities. Zr-PILC dried at 200° C for 4 hours binds CO2 more strongly than the not dried Zr-PILC..

Research on cement recipes for CCS application
(2013) Szczesiul, Patrycja; Paluch, Michał; Złotkowski, Albert
The technology of $CO_2$ sequestration is connected with the necessity of drilling wells, which construction is adapted to aggressive $CO_2$ rich environment. Recipes of cement slurries, used nowadays in carbohydrates production wells, are prepared without considering corrosion occurrence caused by affection of acidic environments originating from carbonate acid radicals. Although increased resistance to sulfates is typical for these cements, this does not guarantee any resistance to corrosive effects of $CO_2$. Density, fluidity, filtration, Marsh Funnel viscosity and rheological parameters measurements (with a twelve-ranged viscometer FANN) were carried out. Using Rheosolution Software, a proper rheological model for each recipe was matched. Corrosive effect on cement rock was obtained through keeping samples in pressure tanks containing compressed $CO_2$ for the period of 180 and 360 days. Directly after taking the samples out of the tanks, flexural and compressive strength tests were carried out with the use of hydraulic press. The results were compared and differences between the samples from $CO_2$ and samples taken from water environment according to API recommendations were presented. The corrosion effect on the samples from both environments was presented with microscopic images. Lengthening of the slurry thickening time and improvement of the slurry fluidity were obtained thanks to adding the third generation superplastifier produced by BASF Polska Sp. z o.o. As a research result a slurry recipe of the best strength has been developed. It can be used for proper sealing in $CO_2$ sequestration well technology.

The model of development of the multihorizontal, hydrocarbon reservoir using advanced exploitation methods
(Wydawnictwa AGH, 2018) Dudek, Jacek; Janiga, Damian; Wojnarowski, Paweł
The decreasing number of discoveries of new large hydrocarbon reservoirs as well as the significant technical progress promote the use of enhanced oil recovery methods. One of the most popular is the sequestration of carbon dioxide in matured or depleted hydrocarbon reservoirs. It allows to achieve the synergistic effect of increased crude oil production and underground sequestration of injected gas. In this paper the model of development of the multi horizontal, oil & gas field using multilateral wells technology connected with simultaneously implementation of the EOR-$CO_2$ methods was presented. Based on the performed model, ten-year productions forecasts were made, which results unambiguously confirmed the significant efficiency of the applied technological solutions with indication of the interesting prospects of their implementation in similar reservoirs.

The role of capillary trapping during geologic CO₂ sequestration
(2015) Knapik, Ewa; Janiga, Damian; Wojnarowski, Paweł; Stopa, Jerzy
Capillary trapping is thought to be one of the primary $CO_{2}$ fixing mechanisms in a porous medium when it is stored. While $CO_{2}$ is injected, gas displaces formation water (brine) in the process called drainage. In the case of the rock mass wetted by water, formation water remains adsorbed in wall pores and micropores. Once the injection process has been completed, gas is displaced by the natural water in the process referred to as imbibition. In that way $CO_{2}$, being a non-wetting phase, is held in the form of dispersed bubbles as an immobile phase. The process occurs fast and allows for a regular storage of large amounts of $CO_{2}$. The process is dependent upon numerous parameters, including capillary pressure and contact angle, but such measurements cannot be easily taken for rock cores in reservoir conditions. Another problem is the fact that it is difficult to separate the impact of such mechanisms as dis-solution and mineral trapping. So far capillary trapping has been deeply analyzed in terms of hydrocarbon recovery and contaminant remediation. The goal of this article is to:– present a physiochemical basis of capillary trapping in CCS context,– simulate the impact of relative permeability hysteresis on geological $CO_{2}$ storage.

Warsaw Trough (Plock Trough) is the deepest part of the Brzena Trough, where the following three structures are located: Sierpc anticline, Bielsk anticline and Bodzanow anticline. These structures represent a prospective site of geological storage of $CO_{2}$ for the major issuers of the gas (over 0.5 Mt / year). The main goal of the work is modeling of the Lower Cretaceous horizons (Hauterivian and Valanginian), Upper Cretaceous (Cenomanian and Turonian) and the layers of the overburden with the use Schlumberger Petrel Integrated Solutions. Well logging data and laboratory data were used to perform shale volume, effective porosity, permeability and lithologic models. Modelling showed the existence of zones with good reservoir properties within individual geological structures: Cenomanian in Sierpc anticline, Hauterivian and Cenomanian in Bielsk anticline and Valanginian and Hauterivian Bodzanow anticline.
