Analysis of the potential heating of selected student residences at The AGH University Of Krakow using the earth’s heat
(Wydawnictwa AGH, 2023) Sapińska-Śliwa, Aneta; Kunasz, Remigiusz; Śliwa, Tomasz
The aim of this study was to adapt the operating parameters of a geothermal heat pump system to the required average power needed to meet the energy for central heating and domestic hot water of selected student residences. Calculations of the average power required by the dormitories in the AGH University Student Campus were carried out, as well as modelling of the deep borehole heat exchanger for the heating load. The designed heating system for the student residences in the AGH University Student Campus using a deep borehole heat exchanger – is sufficient to cover the base heat demand for five four-storey dormitories. During the writing of the paper, the main problem was the low availability of articles on deep borehole heat exchangers. This is due to the continuous development and testing of new engineering ideas. Deep borehole heat exchangers can be use as new boreholes or wells prepared for liquidation. Also use of closed boreholes sometimes is possible, depending on project of liquidation. The future districy heating will use low-temperature heat carrier for heating and cooling. Use borehole fields as rockmass use for heat and/or cool ,storage will be common.

Deformation bands – migration pathways or barriers for hydrocarbons in sedimentary rocks – mini review
(Wydawnictwa AGH, 2023) Solecki, Marek Leszek
A mini review of the topic of deformation bands is presented in the paper. The concept of deformation bands is defined and their impact on the flow of fluids in porous sedimentary rocks is determined. Deformation bands are mm-thick low-displacement deformation zones which have intensified cohesion and lower permeability compared with ordinary fractures. This term was introduced in 1968 in material science, ten years later it appeared in the geological context. This microstructures can occur as barriers or migration pathways for hydrocarbons. Their role depends mainly on microstructural features, and they are also considered in reservoir modeling. The occurrence of deformation bands in Poland is also outlined and discussed - they have been described in Western Outer Carpathians (Magura and Silesia nappes).
