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.
