Petrophysics of Unconventional Reservoirs

Petrophysics of unconventional reservoirs refers to the study of the physical and chemical properties of rock formations that contain hydrocarbons, such as shale or tight sandstones, which require advanced extraction techniques due to their low permeability. This field focuses on understanding the reservoir's porosity, fluid saturation, and mechanical behavior to optimize resource recovery.

Key Terms

Porosity
The measure of void spaces in a material, expressed as a percentage.

Example: A rock with 20% porosity has 20% of its volume as voids.

Permeability
The ability of a material to allow fluids to pass through it.

Example: High permeability rocks allow oil to flow easily.

Hydraulic Fracturing
A technique to extract oil and gas by injecting fluid at high pressure to fracture rock.

Example: Hydraulic fracturing is commonly used in shale gas extraction.

Viscosity
A measure of a fluid's resistance to flow.

Example: Honey has a higher viscosity than water.

Tight Oil
Oil found in low permeability rock formations that require advanced extraction techniques.

Example: Tight oil is often extracted using hydraulic fracturing.

Shale Gas
Natural gas that is found trapped within shale formations.

Example: Shale gas has become a significant energy source in recent years.
