Zone Designation Legend and Log Look Up
|Zone Designations (ZDs) were created in the early 1950s for the Department of
Energy’s natural gas leases and describe specific intervals or zones proven
capable of producing gas in paying quantities. The name of the ZD generally
describes the productive interval included in it. More importantly, the
interval on the log specified in the ZD describes the rights held by the natural
gas lessee. The DOE has consistently used the defined depth interval in a ZD as
an exclusive means of identifying the mineral rights granted in mineral
agreements. (Information Letter 1998-14) |
Resource Land Access has compiled a pdf library of the logs associated with currently active ZDs. These files can be

Notes & Disclaimers
Note 1: Log Annotation Guide: For each ZD type well log, the interval is
annotated with blue, and indicated further by an arrow within the interval. All
other specified tops were provided on the Alberta Energy Regulator
(AER)database, and marked by a red line. For consistency, all depth numbers were
recorded in red.
The type well, log and interval for each ZD were assigned by the Alberta
Energy Regulator (AER).
All raster annotations were performed using the
Imaging for Windows Application, via Microsoft.
Data represented on ZD log is
for general information only.
User is responsible for verifying the data
before making decisions based on these maps and reference wells.
