Pools are distinct hydrocarbon accumulations within a reservoir, tracked separately for production accounting and reservoir management.
An underground accumulation of oil or gas within a porous rock formation, bounded by water or impermeable rock. A single well may produce from multiple pools at different depths. Regulators track production by pool for resource management.
Example: The Nisku A Pool contains oil at 2,500 meters depth.
A regulatory identifier for a specific hydrocarbon pool within a field. Pool codes allow precise tracking of production volumes, reserves, and well count for each distinct accumulation.
Example: Pool code 12345 identifies production from the Viking Formation in a specific field.
Producing oil or gas from multiple pools through a single wellbore without separate measurement. Commingling simplifies operations but requires regulatory approval since it combines production from different sources.
Example: Horizontal wells often commingle production from multiple zones.
The section of a reservoir containing economically recoverable hydrocarbons. Pay zones have sufficient porosity, permeability, and hydrocarbon saturation to justify completion. Wells target one or more pay zones.
Example: This well has 15 meters of pay zone in the Cardium sandstone.
A subsurface rock formation with sufficient porosity and permeability to store and transmit fluids. Reservoirs trap hydrocarbons that migrated from source rocks. Quality reservoirs have high porosity (storage) and permeability (flow capacity).
Example: The Duvernay shale acts as both source rock and reservoir for unconventional wells.
