Pool names
A pool is a specific underground reservoir within a field. While a field covers a geographic area, a pool identifies the exact geological formation and zone being produced. Each pool has both a name and a numeric code assigned by the AER.
How pool names work
Pool names typically combine a formation name with a zone identifier. The format is usually
FORMATION ZONE, where the zone letter or code distinguishes different reservoir
units within the same formation.
Examples of pool names
CHARLIE LAKE FFF— Charlie Lake formation, zone FFFLEDUC D-3A— Leduc formation, D-3A reef unitVIKING A— Viking formation, A poolMANNVILLE BHL— Mannville group, BHL zone (Basal Hoadley)BELLY RIVER J— Belly River formation, J sand
Pool codes
Each pool also has a numeric code for database purposes. For example, pool code
0322252 corresponds to CHARLIE LAKE FFF in the Wembley field. You'll see
these codes in AER data exports and regulatory filings.
Why pools matter
Different pools within the same field can have vastly different characteristics—pressure, fluid type, permeability, and production potential. A well's pool designation determines:
- Which reservoir the well is licensed to produce from
- Production allowables and royalty calculations
- Applicable enhanced recovery schemes
- Regulatory reporting requirements
Pools vs. fields
Think of it hierarchically: Alberta → Field → Pool. A single field like Pembina can
contain dozens of pools across different formations (Cardium, Viking, Mannville, etc.), each with
its own production characteristics and regulatory status.
