Effectively Logging Ahead of and after the ultrasonic rehabilitation there was was a range of comparative geoBefore and immediately after the ultrasonic rehabilitation there a array of comparative geophysical well-logging solutions applied. The measurements were performed by SG GEOTECHphysical well-logging methods applied. The measurements had been performed by SG GENIKA, a.s. (Geologick988/4, 152 00 Praha00 Praha cepy, Czech Republic) plus the aim of Psalmotoxin 1 MedChemExpress OTECHNIKA, a.s. (Geologick988/4, 152 5-Hlubo 5-Hlubocepy, Czech Republic) and also the the process was mostly to confirm to confirm thetechnicaltechnical condition in the borehole the present present situation from the borehole and its aim of the procedure was mostly functionality after the rehabilitation. The measurements intended: and its functionality after the rehabilitation. The measurements intended:Coatings 2021, 11, x. https://doi.org/10.3390/xxxxxwww.mdpi.com/journal/coatingsCoatings 2021, 11,15 ofThe verification in the nicely technical circumstances (internal, external equipment, diameters, perforations, depth); The verification with the internal space of the borehole by optical inspection; The determination of water inflows and their relative yields, plus the clarification with the groundwater flow regime into the nicely.three.6. The Inspection of Nicely Gravel Filter The applied approaches Rilpivirine Inhibitor incorporated:Gamma logging; Neutron neutron logging; Gamma gamma logging in density modification (density logging)–mainly to detect open spaces outside the effectively casing; Cavernometry–to verify the internal diameter of the effectively casing, probable deviations (broken casing, growths), casing joints, and so forth.; Measurement of physicochemical properties of water (conductivity, temperature, percentage of dissolved oxygen, pH index, oxidation-reduction possible)–to detect possible zonality of water within the borehole (from various inflows); Resistivimetry in the application with the labelled fluid dilution method–to clarify the groundwater and detection of inflows; Resistivimetry in the application in the labeled liquid pumping method–to decide all inflows and their yields.The measured parameters have been in comparison with the pre-rehabilitation conditions: water physical and chemical properties, water inflow, yield of permeable positions, effectively filter density, neutron properties of the properly casing, organic gamma activity, plus the borehole diameter curve (cavernometry). The results had been interpreted into the following conclusions: The removal of sediment in the properly bottom elevated the accessible depth in the original 36.0 m for the present 36.five m, which is 0.5 m extra than the declared borehole depth. Comparison on the neutron logging curves showed a slight reduction in signal inside the 117 m bellow terrain (b.t.) section (a higher proportion of water when compared with clay suspension). Inside the 7.350.32 m b.t. section the difference was substantial; even so, this was influenced by a seasonal r.
