Petrophysics
Rock properties that control oil and gas flow: porosity, permeability, and how they are measured and related.
Total vs Effective Porosity: Absolute Porosity Explained
When engineers talk about porosity, they do not always mean the same thing. A rock can contain pores that are connected to…
Classification of Porosity
Porosity can be classified in two ways: by the shape and connection of the pores (a morphological view), and by when the…
Relation Between Porosity and Permeability
Porosity tells us how much fluid a rock can store, and permeability tells us how easily that fluid can flow. The two…
Permeability
Permeability: is a measure of a rock’s ability to conduct fluids. A fluid of known viscosity is pumped through a rock sample…
Laboratory Measurement of Porosity
Porosity can be measured in the laboratory on core samples, from thin sections under a microscope, or in the well with logs.…
Porosity
Porosity is the fraction of a rock’s total volume that is empty space (pores). It tells a petroleum engineer how much oil,…
