NGL - great value for salt NaCl, and for KCl, but for the
40
last much greater value by having Cl, and K .

4.3 Procedure for execution of work

1. Select on diagram material of complex methods GWL
layers, for which is necessary to determine the lithology.
2. Determine the value of geophysical parameters with given
into account the nature of the curve geophysical parameters.
3. Carry out comparison of geophysical parameters
characteristic of which is provided in the theoretical part of the
laboratory work.
4. Issued a report.
5. Save this interpretation results in table 4.1.
