Reservoir geophysics

Geophysical methods are used to explore various physical properties of rocks several kilometres beneath the Earth's surface. Reservoir geophysics focuses on improving methods for recognition of pore fluid type (water, oil, hydrocarbon gas or CO₂) in porous rocks, the total fluid volume, the pressure and the movement of the reservoir fluids in case of an active production or injection process. The knowledge of rock physics is important to hydrocarbon exploration and production monitoring, as well as to the monitoring of CO₂ injection and underground sequestration.
