RECEIVERS COUPLING ASSESSMENT WITH INTERFEROMETRY APPROACH
For projects of downhole microseismic monitoring in Russia, often low signal to noise ratio is discussed. We analyzed several datasets with interferometric approach to exclude receivers coupling as the issue of poor data and interferometry analysis shows good clamping or coupling quality in our datasets even for the dataset with coupling issue. We show on the real data that borehole receiver clamping problems are not always recovered by interferometry. In some cases interferometry may be used as a good test for analysis of weather liquid level reduction was sufficient.
