    Basin-centered gas accumulations in Rotliegend Sandstones
    (Wydawnictwa AGH, 2014) Nosal, Justyna; Waliczek, Marta
    Permian Rotliegend Sandstones are the most important gas reservoirs in north-west Europe (Gast et al. 2010). Those sandstones were deposited in playa, fluvial and aeolian depositional systems (Kiersnowski et al. 2010) and may host both conventional and unconventional deposits.

    Basin-centered gas accumulations in Rotliegend Sandstones - case study of Polish Permian Basin, first results
    (Wydawnictwa AGH, 2012) Nosal, Justyna; Waliczek, Marta
    Permian Basin covers one of the world's largest gas-bearing clastic formation - Permian Rotliegend Group. Reservoirs are supplied by Carboniferous sources, lying directly beneath. Permian Rotliegend sandstones belong to the most important gas bearing formations in Poland. They were deposited in playa, fluvial and aeolian depositional systems (Kiersnowski et al. 2010).

    Diagenetic impact on reservoir quality in deeply buried tight Rotliegend Sandstones - case study of Polish Permian Basin
    (Wydawnictwa AGH, 2014) Nosal, Justyna
    During burial, sediments and rocks undergo physical and chemical changes due to temperature and pressure growth. All these processes are known as diagenesis (Boggs 2009). These changes play an important role in postedpositional modification of reservoir parameters, such as porosity, permeability and filtration.

    Petrophysics of rotliegend sandstones for unconventional tight gas exploration - case study of Polish Permian Basin
    (Wydawnictwa AGH, 2012) Nosal, Justyna
    Tight gas is one of the unconventional gas accumulations. In tight reservoir, natural gas is trapped in impermeable sedimentary rock. Industry defines tight gas reservoir as a maximum 10% matrix porosity and maximum 0.1 mD permeability (excluding fracture permeability) sedimentary rock (Haines 2006). Gas is trapped by low permeability of the reservoir. Down-dip water contact and reservoir trap do not appear. Tight reservoir rock should be characterized by poor reservoir properties - low porosities, extremely low permeability and also small flow rates (Law 2002).

    Reservoir parameters of deeply buried sandstones and their impact on fluid flow – a case study of the Rotliegend Sandstones from the Polish Permian Basin
    (Wydawnictwa AGH, 2015) Nosal, Justyna
    Reservoir parameters of rocks determine its ability to accumulate and transport reservoir fluids such as oil and gas.

    Underground $CO_{2}$ storage - case study of Jastrząbka Stara structure, SE Poland
    (Wydawnictwa AGH, 2012) Nosal, Justyna; Semyrka, Roman
    Carbon dioxide injection into depleted oil fields is widely used. The injection enhances oil recovery and generates other advantages like: (1) decrease of carbon dioxide concentration in the atmosphere and (2) the possibility for $CO_{2}$ emission trade. Geological and reservoir parameters of Jastrząbka Stara structure are discussed in this paper in the context of possible $CO_{2}$ sequestration. Reservoir absorptivity and tightness, overburden thickness, storage capacity as well as social and economical aspects are taken into consideration. Based upon these factors, Jastrząbka Stara oil deposits may be classified as potential carbon dioxide storage site.Detailed data cannot be published due to Polish Oil and Gas Company (PGNiG SA) confidentiality requirements.

    Zastosowanie i wykorzystanie struktur złożowych do zatłaczania $CO_{2}$ na przykładzie struktury Jastrząbki Stara
    (Data obrony: 2011-07-14) Nosal, Justyna

    The main purpose of the presented thesis is to discuss the geological paramaters of subsurface structures as a potential for CO2 storage. These criteria are related to Jastrząbka Stara oil deposit. Properties necessary for CO2 storage for its usage in enhanced oil recovery were included. In addition, were made the analysis of capabilities of increasing size of oil production as a result of carbon dioxide injection to subsurface.
