RESEARCH ON PETROPHYSICAL PROPERTIES OF CHOSEN SAMPLES FROM THE POINT OF VIEW OF POSSIBLE CO2 SEQUESTRATION VÝZKUM KOLEKTORSKÝCH VLASTNOSTÍ VYBRANÝCH HORNINOVÝCH VZORKŮ Z HLEDISKA MOŽNÉ GEOSEKVESTRACE CO2

Abstract Man-made CO2 emissions (the so called anthropogenic CO2 emissions) and their increasing trend can be, by some scientists, considered a serious menace for the sustainable development of mankind, and their reduction a prerequisite for the environment protection. Carbon dioxide is one of the most important gases that cause a greenhouse effect which warms up the earth surface as a consequence of a different heat flow between the earth and the atmosphere. Our laboratory measurements determined the porosity, permeability and grain density for clastic sedimentary rock samples which were drilled from an underground gas storage facility. Additionally, our results showed a reduction in porosity and permeability after a confining pressure was applied. We assume that this effect is caused by internal structure changes due to the repeatedly increased and decreased net pressure applied to the samples Abstrakt Emise CO2 vznikající lidskou činností - tzv. antropogenní emise CO2 a jejich vzestupný trend, mohou být některými odborníky považovány za vážné nebezpečí pro udržitelný vývoj lidstva a jejich omezování za nezbytnou podmínku ochrany životního prostředí. Oxid uhličitý je významný z plynů způsobujících skleníkový efekt, který se projevuje oteplováním zemského povrchu v důsledku změn toků tepelného záření mezi zemí a atmosférou. Laboratorní měření poskytla hodnoty porozity a koeficientu propustnosti horninových vzorků, které byly odvrtány z podzemního zásobníku plynu. Naše měření vykázalo snížení kolektorských parametrů horninových vzorků, které bylo způsobeno změnou vnitřní struktury horniny díky opakovanému zvýšení a snížení tlaku na rostlou část vzorku

Potential Unconventional Gas Plays in Mature Basin of the Czech Republic

Abstract The presence of unconventional resources has been proven in deeper parts of mature oil and gas provinces and coal basins of the world. In this context, it is worth to focus also on the prospects of unconventional gas production from within hydrocarbon provinces of the Moravian part of the Vienna basin. The estimation of hydrocarbon generation potential of Jurasic marls from the Mikulov Formation of the Czech part of the Vienna Basin was performed based on the Rock Eval pyrolysis.

Industrial complexes and their role in industrial tourism – example of conversion

Abstract Sustainable tourism development meets the needs of present tourists and host regions while protecting and increasing its possibilities for the future. It should lead to management of all resources, so as to meet economic, social and aesthetic needs while maintaining cultural integrity, the most important ecological processes, biological diversity and the processes that make life possible. Sustainable tourism products are products that work in accordance with the local environment, society and culture so that the environment, society and culture can benefit and not to become the victims of tourism development. At present, luckily, it is possible to observe, in a wide range of tourist activities and especially in industrialized countries, also increasing interest in so-called industrial tourism aimed at exploring technical monuments. This form of tourism was initially the domain of narrow range of technically-based supporters, but gradually becomes more attractive to the broader public. This article deals with the development and transformation of tourism in the Czech Republic on an example of the Podluzi region and one of its centres - the town of Hodonin. From the tourist activities in the region those specifically attractive ones should be mentioned, which are wine and folklore tourism in close connection with gastronomical tourism and then increasingly popular cycling and water tourism. As for the cycling tourism, there are routes (related to the Greenways programme) leading so that they connect all the major winegrowing sites of the region and also the basic backbone network of cycling routes passing through the territory of the Czech Republic. The development of water tourism is closely linked to industrial tourism, where the important technical monument - the Bata’s channel is used as a waterway. The history of the town of Hodonin is briefly mentioned here in the context of the progressive industrialization of the area (lignite and hydrocarbon mining), its significant downturn and subsequent changes in tourist activities.

Preliminary geochemical modeling of water–rock–gas interactions controlling CO2 storage in the Badenian Aquifer within Czech Part of Vienna Basin

Prediction of hydrogeochemical effects of geological CO2 sequestration is crucial for planning an industrial or even experimental scale injection of carbon dioxide gas into geological formations. This paper presents a preliminary study of the suitability of saline aquifer associated with a depleted oil field in Czech Part of Vienna Basin, as potential greenhouse gas repository. Two steps of modeling enabled prediction of immediate changes in the aquifer and caprocks impacted by the first stage of CO2 injection and the assessment of long-term effects of sequestration. Hydrochemical modeling and experimental tests of rock–water–gas interactions allowed for evaluation of trapping mechanisms and assessment of CO2 storage capacity of the formations. In the analyzed aquifer, CO2 gas may be locked in mineral form in dolomite and dawsonite, and the calculated trapping capacity reaches 13.22 kgCO2/m3. For the caprock, the only mineral able to trap CO2 is dolomite, and trapping capacity equals to 5.07 kgCO2/m3.

EVALUATION OF SURFACTANT PERFORMANCE FOR ENHANCED OIL RECOVERY POSOUZENÍ VHODNOSTI APLIKACE POVRCHOVĚ AKTIVNÍCH LÁTEK (PAL) PRO POTŘEBY ZVÝŠENÍ VYTĚŽITELNOSTI LOŽISEK UHLOVODÍKŮ

Abstract This paper focuses on the field of enhanced oil recovery by means of a chemical flooding of oil deposit especially a surfactant flooding method. The main objective is the application of the aforementioned method at the Czech oil deposit Ždánice - Miocene which bears the crude oil of significant viscosity and gravity that does not allow conventional production methods to be used. We evaluated the performance of various surfactants in the laboratory environment by simulating oil recovery processes Abstrakt Tento výzkum se zabývá problematikou zvyšování výtěžnosti ropy pomocí rozšířeného zavodňování chemikáliemi, z nichž je věnována největší pozornost povrchově aktivním látkám. Dlouhodobým hlavním cílem tohoto výzkumu je aplikace těchto metod v podmínkách české republiky, konkrétně na ložisku Ždánice - miocén, kde vlastnosti obsažené ropy, jako je viskozita a objemová hmotnost, neumožňují použití klasických těžebních metod. Pro vhodnost použití jsme v laboratorních podmínkách simulovali procesy probíhající při těžbě ropy za ložiskových podmínek a hodnotili vliv jednotlivých povrchově aktivních látek na výtěžnost těžké ropy
