|Integrated method of oil and gas quantitative evaluation in petroleum accumulation zones|
|An integrated method of quantitative evaluation of hydrocarbon resources within oil and gas accumulation zones are presented according to approaches established in VNIGRI.
The method is based on the most reliable results of separate counting of hydrocarbons, emigrated from oil and gas source suites (using balance model); applying method of weakest link and kinetic models for evaluation the volume of accumulated hydrocarbons; and using the method of geological analogy when comparing reference (with identified deposits) and evaluated zones within a hydrodynamically isolated section.
Integrated method was tested in the Timan-Pechora oil and gas province for three major complexes. Significant differences, especially in phase composition, are identified for the Upper-Visean and Lower Artinskian complex, in spite of similar results for Ordovician-Lower Devonian and Domanic-Tournaisian oil and gas complexes.
The method of resource evaluation is considered to be relatively independent, and the final results can be used in decision-making.
Key words: oil and gas accumulation zone, oil and gas quantitative evaluation, oil and gas resources, integrated method of hydrocarbon evaluation.
