petrofysica
Petrophysics is the science of the physical and chemical properties of rocks and their interactions with fluids in the pore space of earth formations. In the context of hydrocarbon exploration and production, petrophysics aims to quantify properties such as porosity, permeability, saturations, mineralogy, and wettability to evaluate reservoirs. The term petrofísica is used in Spanish and Portuguese.
Key petrophysical properties include porosity (the fraction of pore space; total porosity versus effective porosity), permeability
Data sources include well logs (gamma ray, density, neutron, sonic, resistivity, NMR), core samples (porosity, permeability,
Petrophysical analysis integrates measurements to deliver formation evaluation, reservoir characterization, and rock property models used in
Practitioner roles include petrophysicists, geologists, and reservoir engineers who collaborate to build petrophysical models, quality-control data,
