    Characteristics of industrial CO₂ emissions in Poland in 2014 in terms of its underground storage
    (2016) Kosowski, Piotr; Mikołajczak, Edyta
    This article contains a detailed analysis and characterization of the Polish base carbon emitters, which was created by the National Center for Emissions Management. This database contains a list of all registered in Poland $CO_{2}$ emitters with annual emissions of more than 1 tonne. On its base the analysis was carried out, divided into economy sectors, provinces, size of emitter and number of installations. Interpretation of the results allows to assess the potential and the need for underground sequestration of carbon dioxide in Poland.

    Możliwości zastosowania metod geofizycznych w problematyce pozyskiwania metanu z pokładów węgla i sekwestracji dwutlenku węgla

    This thesis consists of two parts. First, reviews the present state of application of geophysical methods to primary recovery of coalbed methane (CBM) and secondary recovery by an enhancement with carbon dioxide injection (CO2-ECBM). It appears that seismic, electromagnetic and gravity methods are the most useful and promising in this field of interest. Second, comprises analysis and interpretation of results obtained in simultaneous laboratory measurements of acoustic emission and expansion induced in bituminous coal by sorption of CO2, CH4 and their mixture. Distribution of measured parameters showed influence of type of sorbate used in particular tests. Remarkable similarities in strain and acoustic emission plots confirmed the link between the origins of these two phenomena.

    The analysis of CO₂ injection in depleted gas reservoirs during the sequestration process
    (2015) Gonet, Kamil; Blicharski, Jacek; Rybicki, Czesław
    One of increasingly used methods for reducing carbon dioxide emission to atmosphere is CCS technology (Carbon Capture and Storage). The last element of sequestration technological chain, after capturing and transporting, is $CO_{2}$ storage which is currently considered in: natural environment, oceans and geological structures – of which depleted gas reservoirs have high sequestrating potential mainly by virtue of proven record of geological recognition and high recovery factor, hence, great storage capacity. This paper is connected with first stage of $CO_{2}$ storage in depleted gas reservoir i.e. flow of injected fluid inside the well. Conducted analysis was concerned about $CO_{2}$ flow conditions inside the injection well in various stages of $CO_{2}$ storage process, and furthermore, relation between reservoir pressure, injection rate, well diameter. Moreover, the thermodynamic conditions and its impact on changeability of PVT parameters and hence phase changes were also investigated.
