Oil extraction for biofuel production from edible oils such as palm oil, sunflower oil, canola oil, or soybean oil could be questionable since it affects directly the food supply. Microalgae oil has appeared as a new feedstock for the production of biodiesel as well as bioethanol, biosynthesis gas, or bio-oil through thermochemical and biochemical processes (Lopresto et al., 2017).

Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and gas fields and geothermal systems, and the extent and connectivity of the pore structure control fluid flow and transport through geological formations, as well as the relationship between the properties of individual minerals and the bulk properties of the rock.
