Estimation
at Year 2000

Estimation
of Russian
oil and gas reserves at year 2000 faces the following objectives.
Revising the standard and legal
frameworks. Market economy requires changing to the existing principals
of calculation and classification of natural reserves. A proposal of new
principals titled "Classification of Reserves. . ." has been developed
that includes new regulations for the development of natural resources
and financing mechanisms for geological exploration. Although the proposal
is closely related to the existing principals of reserve estimation
, an
old command language of the geological exploration work that was typical
for the centralized economy has been excluded.
Development of oil and gas
geological exploration. Increase of complication and cost of the geological
exploration work and rejection of the principals of the centralized economy
require reorganizing the Oil and Gas industry. Geological exploration has
three phases: prospecting, evaluation, and exploration. Reserve estimation
,
review, and registration should correlate with these three phases.
The trustworthiness of the geological exploration work will be increased substantially if detailed seismic exploration (or 3D seismic) is performed along with exploration drilling.
Development of a methodology
for hydrocarbon reserve estimation
. Modem computer technologies improve
the effectiveness of reserve
estimation
. A main problem of the reserve
estimation
is the generation of the geological model. Experience, knowledge,
and common sense, which a geologist gains over decades, are critical for
solving this problem. Developing a system that imitates a professional
method of the problem solution is the most comprehensive method of generalizing
and disseminating the experience and knowledge. Several similar systems
(SAND, REEF, FLUID, and others) have been developed in Russia for reserve
estimation
