3.3 Application for Good Production Practice—Primary Depletion Pools
This section deals only with GPP applications for pools under primary depletion.
GPP removes a pool from restrictions imposed by the ERCB’s monthly MRL Order and is
granted under Section 10.060 of the Oil and Gas Conservation Regulations. Under GPP, the
wells in a pool are not restricted by base allowable or GOR penalties. However, as the name
implies, operators are expected to produce the wells in accordance with good engineering
practices to optimize oil recovery. The ERCB may rescind GPP approval if new information
or technology indicates that production under GPP may affect conservation or the rights of
other owners in the pool. GPP may be granted with concurrent production restrictions on gas
cap production or other conditions.
Note that for pools under primary depletion, GPP is granted to the pool, not to individual
wells. For pools where EOR schemes exist, GPP is usually granted only to the ER oil scheme
areas.
3.3.1 Requirements for an Application for GPP
Requirements
Comments
1) Your geological interpretation of the pool,
including
a) a net pay isopach map of the pool,
including both oil and gas if there is an
associated pool,
b) where pool delineation or fluid interface
locations are based on structural
interpretation, a structure contour map
of the pool and offsetting area,
c) an interpreted and annotated log crosssection
or representative well log(s)
showing the
i) stratigraphic interpretation of the
zone(s) of interest,
ii) interpretation of the fluid interfaces
present,
For primary pools, GPP is granted to the entire
oil pool. Therefore, the application must provide
a geological interpretation of the entire pool, not
just lands you own.
If it will help to clarify your basis for pool
delineation or other aspects of your geological
interpretation, you should submit a log crosssection
containing wells both within and outside
of the pool. As a minimum, you must submit at
least one representative well log from a well in
the pool showing the information required in
item 1(c).
You must provide a clear picture of your
geological interpretation, including the potential
for further pool development.
iii) completions and treatments to the
wellbore(s), with dates,
iv) cumulative production,
v) finished drilling date and kelly
bushing (KB) elevation, and
vi) scale of the log readings, and
