NMTK data Processing Program “NMR Processor”

It is used in the study of oil and gas wells by the method of nuclear magnetic logging in a strong field, it allows you to analyze the measurement results and evaluate the filtration-capacitive characteristics of rocks.

The main design capabilities of the complex :
calculation of differential spectra;
calculation of integrated spectra;
calculation of partial spectra;
calculation of bins;
calculation of total porosity;
separation of total porosity into components: clay porosity, effective porosity, capillary-bound water;
permeability calculation by capillary-grating model;
permeability calculation according to the Timur model;
permeability calculation according to the Timur-Coats model;
permeability calculation according to the average T2 model;
calculation of the porosity parameter by capillary-grating model;
pre-filtering the signal using the low-pass filter;
pre-filtering the signal using the Wavelet filter;
subtraction of the spectra (in order to determine the saturation of the reservoir with different types of fluids);
subtraction of relaxation curves.

Data visualization features :

the ability to view the primary NMC data;
the ability to view spectra;
data visualization (building tablets) and output to a printer;
the ability to graphically present spectra on a tablet in the form of bins, wave patterns and color charts.

Additional features :

the ability to edit primary data;
Export data to ASCII
import of external data (GIS, etc.);
depth matching, changing the interval (length) of the LIS file.

Input and output data :

input data: spectral registration files in the LIS format of the international standard (LIS-79);
output data: results of measurements and processing in the form of LIS and LAS files and hard copies of well logs;
the possibility of interval processing (recalculation of individual intervals using adjusted parameters, changing cut-offs to obtain effective clay porosity and porosity at individual intervals).
