Abstract

In this study, we use compositional and textural data of beach sands from the Colombian Caribbean margin as inputs for diagenesis simulation with the objective of evaluating the impact of sand composition, texture, and burial history on porosity and permeability evolution using Upper Miocene burial histories at three locations offshore. In addition to simulations that use the measured composition and texture of the modern sands as a starting point, we consider sensitivity scenarios that include the introduction of 5 % and 15 % detrital clay matrix or 5 % and 15 % carbonate cement. The results indicate that variations in composition lead to different pathways for porosity loss, primarily due to differences in mechanical properties (rigid vs. ductile fragments vs. bioclasts). Moreover, different amounts of detrital matrix and early carbonate cements cause varying degrees of compaction and quartz cementation, ultimately determining different petrophysical properties. While the models presented in this paper are not calibrated to available data from relevant onshore and offshore reservoirs, the obtained results are readily comparable with porosity and permeability ranges reported in public documents from the Colombian National Hydrocarbon Agency (ANH) for the Neogene reservoirs from the eastern, central, and western Caribbean regions.
