Specifics of downhole logging data for time series analysis and cyclostratigraphy

There is a large amount of downhole logging data gathered for scientific and commercial purposes, but studies applying time series analysis and cyclostratigraphy are not abundant. Especially the fast availability of logging data makes it valuable, also for decisions on which cores to investigate first. Here, we summarize the specific properties of downhole logging data most relevant for time series analysis and cyclostratigraphy. As for data from core- or outcrop analysis, it is important to be aware of both the potential and also possible issues of data. For logging data challenges, include changing borehole diameter, influences of drilling fluids and the fact that logged data may be a composite record. This contribution tries to give a concise summary of chances and possible challenges.
