Calculation Of Reserves And Economic Evaluation Of Oilfield Xiasiwan Temple Bay Area Long Reservoir Group

The research direction of the reservoir tends to microscopic, quantitative. China’s reserves classification criteria and reserve classification standards of Western countries is basically the same meaning, and the most widely used of volumetric method to calculate the oil is the main method of geological reserves of gas reservoirs. Before investment decisions, the economic evaluation of oil investment is the most important work of the international oil companies. The research and application of Petroleum Exploration and Development Economic Evaluation, traditional decision analysis method has been widely used, but compared with the practice of foreign economic evaluation of oil and gas field exploration and development, lack of flexibility and practicality. Real options method linked financial markets and investment decisions, subjective forecast of future cash flows,Bay Area Xiasiwan oilfield Temple Yanchang reservoir mainly low porosity and low permeability oil field. In this paper, drilling, logging, logging and testing data, this Chang2reservoir reserves are mainly carried out on the basis of the sedimentary facies, rock characteristics,pore structure characteristics,diagenesis,physical characteristic parametric studies. Economic evaluation of the study area, the first time the real options method Black-Scholes model used in oilfield Xiasiwan Temple Bay Area Economic Evaluation, including the three factors of the oil price, recoverable reserves and the cost began to dynamic sensitivity analysis, and comparative analysis of economic parameters,meanwhile, the the traditional financial net present value of the economic evaluation method.The test results show that the real options method is able to more accurately reflect the results of the evaluation of the real economy in the area, greater investment value investment opportunities along with the uncertainty of the investment projects, changes in recoverable reserves significant impact assessment estimated the economic value of the study area.
