In the economic evaluation to the oil & gas explored reserves, central task is selecting and deciding economic evaluation parameters.

The reservoir engineering evaluation of the submitted explored reserves and economic evaluation which based upon this is of great importance to the recognitional extent of the reserves and exploitation strategy.

Mam control factors of technical recovery of newly incremental proven reserves;

Analysis on factors of influencing the increase of proven reserves;

In big foreign oil companies, an integrated management system is currently deployed for oil exploration and development, the commercial value of proven reserves is high.

Determination of the proved reserves area of low permeability reservoirs in Daqing Oilfield;

A broom-type model for predicting incremental proved reserves;

Coal-bed methane resources and proved reserves in Fanzhuang Block of Qinshui Basin

The authors of the paper probe the principle,approach,operating procedure and the existing problems of predicting hydrocarbon resource by reservoir size sequence,the approach is applied to predict the remaining proved reserve at Dongying sag by .

After the discovery of Jingbian Gas Field with proved reserves over 100 billion cubic meters in the Lower Paleozoic,the Yulin,Sulige and Wushenqi gas fields with the same reserves in the Upper Paleozoic of Ordos Basin were also discovered and proved up.

Analysis shows that newly added proved reserves during the "ninth five - year plan" period in Jiyang depression are basically composed of upgraded reserve, progressive reserve and newly discovered reserve, with the upgraded reserve being the dominant.

A discovery degree of petroleum resources is one of important factors that indicate petroleum exploration maturity.
