Highlights—Dueling pore systems from bioturbation

Bioturbation is an important post-depositional process that can alter sedimentary textures, porosity, and permeability. Here, Baniak et al. examine the influence of burrow geometry and connectivity on porosity and permeability within the Upper Jurassic Ula Formation of the Norwegian Central Graben. Spot permeametry data and numerical modeling of this shoreface succession illuminate relationships among burrow morphology, bioturbated volume, and burrow connectivity. These data provide insights for a conceptual framework for assigning bulk permeability to reservoir media, useful to better characterize hydrocarbon deliverance through bioturbated sandstone reservoirs with dual porosity and dual permeabeability systems.
