Over the past couple decades, the understanding of petrophysical parameters in bioturbated hydrocarbon reservoirs and aquifers has expanded greatly. Specifically, insights into how bioturbation impacts the distributions of porosity and permeability has occurred through both direct measurements (spot-permeameter, high-resolution imaging) and computer modelling of features such as bioturbation intensity and burrow architecture. Within this review paper, a detailed overview of the concepts associated with the application of ichnology to reservoir fluid flow from both a historical and modern perspective are completed. Following this, the nature of biogenic permeability and porosity is discussed and we inspect the ways in which burrows might influence those parameters. Focus is ultimately then applied to summarizing the most common methods used to quantify bioturbation within rock samples. The overview is then underpinned by a number of different case studies which highlight the variations of biogenic permeability encountered within a wide-ranging classification system, and we summarize those at the end.
