Directive 065 - Energy Resources Conservation Board

Requirements Comments
wellbore(s), with dates,
iv) cumulative production,
v) finished drilling date and kelly
bushing (KB) elevation, and
vi) the scale of the log readings, and
d) a tabulation of the interpreted net pay,
porosity, and water saturation for each
well in the pool, along with the cutoffs,
methodology, formulas, and constants
used.
10) An evaluation of the oil and gas reserves for
the pool and for your lands, including
a) an estimate of the initial oil volume and
gas volume in place,
b) an estimate of the oil and gas recovery
factors,
c) a description of the methods used in
determining (a) and (b) above (e.g.,
material balance, volumetric analysis,
model study, a comparison of analog
pools), and
d) the supporting data used in determining
(a) and (b) above and the sources of the
data (e.g., pressure/volume/temperature
[PVT] properties and source, pressure
data and source).
11) A discussion of drainage, including
a) evidence showing that the reserves
underlying your lands have been drained
subsequent to the completion of your
well in the pool, and
b) an estimate of the total amount of
inequitable drainage that has occurred
from your lands since your well was
completed in the pool, together with
details of how the drainage was
calculated.
These data assist the ERCB to assess your
mapping and reserves calculations requested
in the following item. In addition, the data
may be used to allocate production (see
item 14).
The reserve estimates confirm that there are
reserves available for production.
You should provide all data used in obtaining
the reserves estimates so that your analysis
can be duplicated.
Drainage is not a prerequisite for the issuance
of a common processor order but could be
one factor in determining the need for an
order. In addition, the ERCB considers the
extent to which drainage has occurred in
evaluating what the effective date of the
order should be.
In cases where a well has remained shut in,
you can confirm drainage by summarizing a
minimum of two pressure tests taken on the
well. If you are arguing that your currently
producing well is not producing at sufficient
rates to recover an equitable share of
