Combining logging while drilling (LWD) azimuthal density images from real-time measurements with wireline electrical borehole imaging logs minimizes risks, maximizes data acquisition, and creates a better understanding of reservoir characteristics than using either of the tools alone. The azimuthal density images provide structural images in real time, but not fine sedimentary details. Meanwhile, wireline electrical borehole images fill in detail in stratigraphic dip analysis. Comparing the median grain size derived from core sieve analysis with the pseudo median grain size derived from the image resistivity distribution of wireline electrical borehole imaging data confirmed that the results are comparable and wireline electrical borehole image can substitute core analysis in some extent to extract some textural information from sands.
