A Multi-Facetted Approach to Stratigraphy: One that is Applicable to the Oil and Gas Industry?
© 2014, Springer-Verlag Berlin Heidelberg. The importance of high resolution, chronostratigraphically-grounded correlations in the oil and gas industry is being increasingly recognized as more and more challenging reservoirs are sought and exploited. The “traditional” approaches of wireline log correlation, biostratigraphy and seismic correlation commonly do not provide confident or high resolution chronostratigraphic correlations. Here, we document the results of an elemental chemostratigraphic, isotopic chemostratigraphic and magnetic susceptibility stratigraphic study on the Upper Miocene reef complexes on the southern coast of Mallorca. The aim of the paper is to demonstrate the potential for recognizing chronostratigraphic surfaces and units in these sequences by applying the stratigraphic techniques listed above and to comment on their suitability for subsurface application. Magnetic susceptibility data define maximum regressive surfaces that can be related to base level fluctuation. Elemental data enable reef complexes of differing ages to de characterized based on elements and element ratios that are reflecting changes in wind-blown and tuffaceous detritus. Carbon and oxygen isotope data have been reset by meteoric diagenesis and therefore do not offer chronostratigraphically significant information.
