The reservoir is a porous and permeable lithological unit or set of units that holds the hydrocarbon reserves.
Analysis of reservoirs at the simplest level requires an assessment of their porosity (to calculate the volume
of in situ hydrocarbons) and their permeability (to calculate how easily hydrocarbons will flow out of them).
Some of the key disciplines used in reservoir analysis are the fields of structural analysis, stratigraphy,
sedimentology, and reservoir engineering.
Core Lab-developed evaluation techniques are used to provide detailed geologic descriptions and interpretation
of formation mineralogy, depositional environment, pore structures, and geochemical characteristics.
