Definition of Reservoir

In petroleum industry, reservoir fluids is a mixture of
hydrocarbons (oil and/or gas), water and other non-hydrocarbon
compounds (such as H2S, CO2, N2, ...)

Physical Resources
 In-place Reservoir Resources
 Reservoir’s energy source resulted from the
initial pressure & drive mechanisms during
production
 Available flow conduits thanks to reservoir’s
characteristic properties such as permeability
distribution.
