Directive 065: Resources Applications for Oil and Gas Reservoirs ...

Requirements
c) an interpreted and annotated log crosssection
or representative well log(s)
showing the
i) stratigraphic interpretation of the
zone(s) of interest,
Comments
Your application will have fewer processing
delays if you provide a clear picture of your
geological interpretation, including the
potential for further pool development.
ii) interpretation of the fluid interfaces
present,
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
d) a tabulation of your interpreted net pay,
porosity, and water saturation for each
well in the pool, along with the cutoffs,
methodology, formulas, and constants
used.
2) Your evaluation of the oil and gas reserves
for the pool, 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
If there are sufficient pressure, production,
and PVT data, a material balance evaluation
should be done and compared to the
volumetric results.
Failure to provide the calculation methods
and supporting data will delay processing of
your application.
It is not necessary to provide production plots
for the wells, except to illustrate a particular
point or issue (e.g., decline analysis, specific
well performance issues).
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).
