Effectively Logging Just before and after the ultrasonic Carbendazim Fungal rehabilitation there was was a range of comparative geoBefore and following the ultrasonic rehabilitation there a array of comparative geophysical well-logging approaches applied. The measurements had been performed by SG GEOTECHphysical well-logging solutions applied. The measurements had been performed by SG GENIKA, a.s. (Geologick988/4, 152 00 Praha00 Praha cepy, Czech Republic) as well as the aim of OTECHNIKA, a.s. (Geologick988/4, 152 5-Hlubo 5-Hlubocepy, Czech Republic) plus the the process was primarily to confirm to verify thetechnicaltechnical condition with the borehole the existing current situation of the borehole and its aim on the procedure was primarily functionality just after the rehabilitation. The measurements intended: and its functionality right 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 with the effectively technical situations (internal, external gear, diameters, perforations, depth); The verification of the internal space with the borehole by optical inspection; The determination of water inflows and their relative yields, plus the clarification of the groundwater flow regime in to the well.three.six. The Inspection of Properly Gravel Filter The applied solutions included:Gamma logging; neutron neutron logging; Gamma gamma logging in density modification (density logging)–mainly to detect open spaces outdoors the effectively casing; Cavernometry–to verify the internal diameter of the effectively casing, probable deviations (broken casing, growths), casing joints, etc.; Measurement of physicochemical properties of water (conductivity, temperature, percentage of dissolved oxygen, pH index, oxidation-reduction possible)–to detect feasible zonality of water inside the borehole (from unique inflows); Resistivimetry inside the application with the labelled fluid dilution method–to clarify the groundwater and detection of inflows; Resistivimetry inside the application in the labeled liquid pumping method–to establish all inflows and their yields.The measured parameters have been compared to the pre-rehabilitation circumstances: water physical and chemical properties, water inflow, yield of permeable positions, effectively filter density, neutron properties of your effectively casing, organic gamma activity, as well as the borehole diameter curve (cavernometry). The results had been interpreted into the following conclusions: The removal of sediment from the properly bottom improved the available depth in the original 36.0 m towards the existing 36.5 m, which can be 0.five m far more than the declared borehole depth. Comparison on the neutron logging curves showed a slight reduction in signal in the 117 m bellow terrain (b.t.) section (a greater proportion of water in comparison to clay suspension). Inside the 7.350.32 m b.t. section the difference was important; nonetheless, this was influenced by a seasonal r.
