iii) completions and treatments to the<br />
wellbore(s), with dates,<br />
iv) cumulative production,<br />
v) finished drilling date and kelly<br />
bushing (KB) elevation, and<br />
vi) the scale of the log readings, and<br />
d) a tabulation of the interpreted net pay,<br />
porosity, and water saturation for each<br />
well in the pool, along with the cutoffs,<br />
methodology, formulas, and constants<br />
used.<br />
9) An evaluation of the oil and gas reserves for<br />
the pool and for your lands, including<br />
a) an estimate of the initial oil volume and<br />
gas volume in place,<br />
b) an estimate of the oil and gas recovery<br />
factors,<br />
c) a description of the methods used in<br />
determining (a) and (b) above (e.g.,<br />
material balance, volumetric analysis,<br />
model study, a comparison of analog<br />
pools), and<br />
d) the supporting data used in determining<br />
(a) and (b) above and the sources of the<br />
data (i.e., pressure/volume/temperature<br />
[PVT] properties and source, pressure<br />
data and source).<br />
10) A discussion of drainage, including<br />
a) evidence showing that the reserves<br />
underlying your lands have been drained<br />
subsequent to the completion of your<br />
well in the pool, and<br />
These data assist the ERCB to assess your<br />
mapping and reserves calculations requested<br />
in the following item. In addition, these data<br />
may be used to allocate production (see<br />
item 14).<br />
The reserves estimates confirm that there are<br />
reserves available for production.<br />
You should provide all data used in obtaining<br />
the reserves estimates so that your analysis<br />
can be duplicated.<br />
Drainage is not a prerequisite for the issuance<br />
of a common carrier order but could be one<br />
factor in determining the need for an order.<br />
In addition, the ERCB would consider the<br />
extent to which drainage has occurred in<br />
evaluating what the effective date of the<br />
order should be.<br />
