f Compartmentalisation in Rotliegend Gas Fields, Examples from Offshore and Onshore the Netherlands

Initiaily a single gas field is characterised by a single GWC, a single pressure system (on the geological timescale), a single gas composition and one GIIP. Spatially bounded subvolumes that need to be accessed individually to ensure their adequate depletion on the production timescale are called "compartments". There is no strictly physical definition for compartmentalisation. The time value of money and limitations of present-day well technology combine with natural, ofien complicated, internal reservoir architecture and associated geologic distributions of physical properties to make a field compartmentalised.
