Downhole logging data and its suitability for cyclostratigraphy and time series analysis
Extensive borehole logging datasets are being gathered for commercial and scientific purposes, but studies exploring their full potential through applying time series analysis remain sparse. Typically, fast available logging data are relatively complete and may contain valuable paleoenvironmental information related to, amongst other signals, orbital forcing. Here, we briefly summarize the most relevant properties of borehole logging data and pitfalls in the context of time series analysis and cyclostratigraphy. In comparison to interpretation of data from core- or outcrop analysis, it is important to be aware of potential issues such as the effect of variation in borehole diameter and the influences of drilling fluids, and that presented logs may consist of merged results logged in several depth sections.
