“…The application of the pressure test used in the CCS industry to establish the ''well is loss-free'' above the storage horizon is possible in principle. It would, however, require destroying a possibly intact composite system above the storage horizon (Crow et al 2009;Reinicke and Fichter 2010).…”

“…A hydraulic isolation behind the casing is generally assumed, if a minimum interval of quality cementation, whose value depends on the specific formations and the companies involved, can be identified. Measurement methods have evolved to the point, where evaluation can be carried out with a high degree of confidence (Reinicke and Fichter 2010;Schutze et al 2012). In the case of excessive loading, the integrity of oil wells is commonly assessed by a water test, as for instance in the case of thermal wells, to provide evidence that the ''well is pressure-tight''.…”

“…According to the current state of scientific research, it is ascribed solely to the plastic behavior of the natural salt deposits. This property is commonly regarded as an essential criterion for the suitability and safety of subsurface storage, taking into account the storage of gases in the subsurface (Reinicke and Fichter 2010).…”

Risk assessment of abandoned wells affected by CO2

Flawless operation during injection and a longterm seal of the storage reservoir after injection are the prerequisites for successful CO 2 storage in the geological subsurface. This requires the sealing of the porous permeable horizons by a tight caprock and long-term integrity of open and abandoned wells which have penetrated these horizons. As a basic requirement for the inception of a CO 2 injection scheme in any sequestration project, the integrity of the existing wells in the field must be proven. This paper reviews the relevant items including the geology, relevant wells and their standards, well integrity, and integrity evaluation methods. At the end, a novel concept is introduced to evaluate well integrity for abandoned wells. It is concluded that the verification of technical well integrity is significantly more difficult for abandoned wells, because measurements and tests to close information gaps are no longer possible. If information is lacking for a direct assessment, the quantification of the risk of leakage is only possible indirectly. For an indirect assessment, a realistic risk assessment should consider the composite system casing-cement-rock as a whole and also include self-healing caused by CO 2 interaction with the composite system and/or the indigenous rock. The proposed new method covers both qualitative and quantitative analysis, and it is more comprehensive, sophisticated and easier to implement.

“…Leakage of CO 2 through old boreholes has occurred in relation to EOR projects in the United States, 3 but Porse et al (2014) suggest that the perceived risk of CO 2 well blowouts in EOR operations is greater than the technical risk. Kü hn et al (2013) tested 12 legacy boreholes for a possible enhanced gas recovery project in the depleted Altmark natural gas field in Germany, and the authors found that these existing wells would still maintain integrity after injecting 100,000 t of CO 2 . Still, leakage risks could be higher in areas that have historically produced oil and gas, primarily owing to the higher density of legacy wellbores.…”

Given a scarcity of commercial-scale carbon capture and storage (CCS) projects, there is a great deal of uncertainty in the risks, liability, and their cost implications for geologic storage of carbon dioxide (CO 2 ). The probabilities of leakage and the risk of induced seismicity could be remote, but the volume of geologic CO 2 storage (GCS) projected to be necessary to have a significant impact on increasing CO 2 concentrations in the atmosphere is far greater than the volumes of CO 2 injected thus far. National-level estimates of the technically accessible CO 2 storage resource (TASR) onshore in the United States are on the order of thousands of gigatons of CO 2 storage capacity, but such estimates generally assume away any pressure management issues. Pressure buildup in the storage reservoir is expected to be a primary source of risk associated with CO 2 storage, and only a fraction of the theoretical TASR could be available unless the storage operator extracts the saltwater brines or other formation fluids that are already present in the geologic pore space targeted for CO 2 storage. Institutions, legislation, and processes to manage the risk, liability, and economic issues with CO 2 storage in the United States are beginning to emerge, but will need to progress further in order to allow a commercial-scale CO 2 storage industry to develop in the country. The combination of economic tradeoffs, property rights definitions, liability issues, and risk considerations suggests that CO 2 storage offshore of the United States may be more feasible than onshore, especially during the current (early) stages of industry development.

Ocena migracji składników gazu ziemnego w złożu Borzęcin na podstawie wyników analiz izotopów trwałych wodoru i węgla Jedna z pierwszych instalacji EGR (ang. Enhanced Gas Recovery -wzmożonego wydobycia gazu) na świecie funkcjonuje na złożu Borzęcin (SW Polska). Instalacja umożliwia zebranie doświadczenia w rozwoju technologii CCS (ang. Carbon Capture and Storage -wychwyt, transport oraz trwała izolacja CO 2 ) na skalę przemysłową. Ze względu na niewielkie rozmiary złoża technologia ta daje możliwość rozwoju badawczego EGR, przy czym wszystkie procesy związane z zatła-czaniem ditlenku węgla i siarkowodoru są możliwe do obserwacji w stosunkowo niedługiej skali czasu. Głównym celem badań była próba oceny migracji zatłaczanych gazów poprzez pobór i analizę izotopów trwałych wodoru i węgla w gazach z poszczególnych otworów wiertniczych. Dzięki uzyskanym wynikom możliwa jest ocena migracji składników gazu ziemnego w złożu Borzęcin. W rezultacie przeprowadzonych badań otrzymano nowe narzędzie do oceny efektywności wzmożonej eksploatacji gazu, które następnie może być zastosowane w technologiach związanych z CCS. Skład izotopowy wodoru (n = 63) w metanie mieścił się w zakresie od -159,3‰ do -85,2‰ (średnia -114,6‰), a skład izotopowy wę-gla (n = 92) w tym metanie wyniósł od -46,93‰ do -17,87‰ (średnia -35,22‰). Skład izotopowy węgla (n = 88) w ditlenku węgla osiągnął wartość od -23,33‰ do -3,11‰ (średnia -13,35‰).Słowa kluczowe: wzmożone wydobycie gazu, metan, ditlenek węgla, izotopy trwałe. Migration assessment of natural gas components in the Borzecin deposit based on results of hydrogen and carbon stable isotope analyzesOne of the first installations in the World, based on the EGR (Enhanced Gas Recovery) operates in Borzecin (SW Poland). Thus creating the opportunity to gather experience in the development of CCS (Carbon Capture and Storage) on an industrial scale. Due to the small size of the deposit, the technology allows great research opportunity to develop Enhanced Gas Recovery and all the processes associated with the injection of CO 2 and H 2 S are possible to observe in a relatively short time scale. The main goal of the research is tracing migration fronts of injected gases threw sampling and isotopic analysis of gases from numeral boreholes. Gathered results gave the opportunity to get an appraisal of gas migration in the Borzecin NAFTA-GAZ 28Nafta-Gaz, nr 1/2017Kluczowym zagadnieniem dla Polski, z uwagi na przyjęcie Ramowej Konwencji Narodów Zjednoczonych (Rio de Janeiro, 1992) i późniejszego uzupełnienia dotyczącego przeciwdziałania globalnemu ociepleniu (Kioto, 1997), staje się ograniczenie emisji gazów cieplarnianych, w szczególności CO 2 , do atmosfery. Ze strategicznego punktu widzenia bardzo istotna jest minimalizacja negatywnego skutku ekonomicznego takiej polityki Unii Europejskiej. Można to osiągnąć dzięki magazynowaniu CO 2 w strukturach geologicznych, związanemu z EGR (ang. Enhanced Gas Recovery -wzmożoną eksploatacją gazu ziemnego) w ramach CCS (ang.
