Shale Gas Reservoir Properties

Petrophysical properties of shale gas reservoirs refer to the physical and chemical characteristics of the rock, such as porosity, permeability, and mineral composition, that influence the storage and flow of natural gas within the shale formation. These properties are critical for assessing the reservoir's capacity to hold and transmit gas, impacting extraction strategies and economic viability.

Key Terms

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

Example: High porosity in shale allows for more gas storage.

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

Example: Low permeability in shale can hinder gas flow.

Saturation
The degree to which a pore space is filled with fluids.

Example: Gas saturation indicates how much gas is present in the pores.

Hydraulic Fracturing
A technique used to extract gas by injecting fluid into the rock at high pressure.

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

Rock Mechanics
The study of the behavior of rock materials under various conditions.

Example: Rock mechanics help predict how shale will respond to drilling.

Gas Reservoir
A subsurface pool of hydrocarbons contained in porous rock.

Example: Shale gas reservoirs are a significant source of natural gas.
