As an active remote sensing instrument, TLS can provide the intensity information of scanned reservoir outcrops depending on their mineralogical and petrophysical characteristics. This paper discussed the potential of intensity data as a tool to identify sand bodies in reservoir outcrops. Intensity is proportional to the reflectance of the target at the laser wavelength of TLS after it is corrected for distance influence. We discussed the correlation between intensity and spectral reflectance of rock samples. The correlation coefficient decreased from 0.9378 to 0.6353 with the increase of cover thickness. TLS intensity can be used for sandstone and mudstone classification and one of the optimal condition is no cover on the outcrop surface. In Tanjiahe outcrop, Yanchang tight sandstone Formation, Erdos basin, China, K-means method and support vector machines method with optimal parameters were used for separating sand bodies from mudstone based on TLS intensity. Results indicated that TLS intensity can be efficiently exploited to identify sand bodies in reservoir outcrops.
