Foreign Oil And Gas Reserves System Analysis

Petroleum Reserves is one of the important things in national resources managing and programming and the guide of stage work and the basis of long-term development program making.At the same time, it is the gist of tax calculating and financial forms making . Comparing and analyzing the petroleum classification system between China and foreign countries ,we can improve the managing and evaluating of petroleum reserves .This article introduces the basic steps about petroleum exploration and exploitation , tasks and methods in different explore stages .It also introduces some basic conceptions about petroleum resources .After comparing and analyzing the petroleum classification ,the reserves calculation and reserves evaluation between China and foreign countries, the actual petroleum classification standard in U.S.A pays more attention to the economic speciality of petroleum resources .The final product of exploration is viable and recoverable reserves ,it is a dynamic matter ,always exchange with the variant economic situation .In China , much more attention is paid to the exploration degree and geological situation .The essence is the original reserves in place , and the final product of exploration is technical and recoverable reserves .Because of complex geological situation in China ,the discovery of the oil in place is gradual ,namely from beforehand exploration to assess drill then exploit .Along with this procedure ,the reserves are more and more accurate , more approaching the actual origin .In the economic society ,the classification of reserves in U.S.A is more operational .In order to take part in Internationalization ,China must establish a new managing model for the reserves .Among these ,the most important thing is to transfer the reserves into assets ,then constitute a system of petroleum reserves evaluation ,renew the reserves manage system ,build up a new method for reserves operation .After analyzing the difference which may affect the exploration and exploitation activities , eliminate the difference ,setting up a series of estimate methods about reserves ,as simple as possible in reserves calculating ,improving the level of reserves software are feasible suggestions.
