iii) completions and treatments to the
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.
These data assist the ERCB to assess your
mapping and reserves calculations requested
in the following item. In addition, these data
may be used to allocate production (see
item 14).
9) An evaluation of the oil and gas reserves for
the pool and for your lands, including
The reserves estimates confirm that there are
reserves available for production.
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 (i.e., pressure/volume/temperature
[PVT] properties and source, pressure
data and source).
You should provide all data used in obtaining
the reserves estimates so that your analysis
can be duplicated.
10) 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
Drainage is not a prerequisite for the issuance
of a common carrier order but could be one
factor in determining the need for an order.
In addition, the ERCB would consider the
extent to which drainage has occurred in
evaluating what the effective date of the
order should be.
