Nicely Logging three.5. Properly Logging Before and following the ultrasonic YN968D1 medchemexpress rehabilitation there was was a selection of comparative geoBefore and just after the ultrasonic rehabilitation there a array of comparative geophysical well-logging methods applied. The measurements had been performed by SG GEOTECHphysical well-logging techniques applied. The measurements have been performed by SG GENIKA, a.s. (Geologick988/4, 152 00 Praha00 Praha cepy, Czech Republic) and the aim of OTECHNIKA, a.s. (Geologick988/4, 152 5-Hlubo 5-Hlubocepy, Czech Republic) as well as the the process was mainly to verify to confirm thetechnicaltechnical situation with the borehole the existing existing situation in the borehole and its aim in the procedure was mainly functionality following the rehabilitation. The measurements intended: and its functionality following the rehabilitation.

The Inspection of Effectively 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 properly casing; Cavernometry–to confirm the internal diameter from the properly casing, feasible deviations (broken casing, growths), casing joints, etc.; Measurement of physicochemical properties of water (conductivity, temperature, percentage of dissolved oxygen, pH index, oxidation-reduction prospective)–to detect achievable zonality of water inside the borehole (from distinct inflows); Resistivimetry AS-0141 web within the application of the labelled fluid dilution method–to clarify the groundwater and detection of inflows; Resistivimetry within the application with the labeled liquid pumping method–to establish all inflows and their yields.The measured parameters have been when compared with the pre-rehabilitation circumstances: water physical and chemical properties, water inflow, yield of permeable positions, properly filter density, neutron properties from the well casing, natural gamma activity, and also the borehole diameter curve (cavernometry). The outcomes have been interpreted into the following conclusions: The removal of sediment from the well bottom improved the offered depth from the original 36.0 m to the existing 36.5 m, which is 0.5 m much more than the declared borehole depth. Comparison of your neutron logging curves showed a slight reduction in signal in the 117 m bellow terrain (b.t.) section (a greater proportion of water compared to clay suspension). In the 7.350.32 m b.t. section the distinction was considerable; on the other hand, this was influenced by a seasonal r.
