    Abstract
  • Reserve evaluation is the core of asset value evaluation of new investment projects in overseas oil and gas field development and determines the investment income and formulation of a development plan. A method of reserve evaluation was established by using geological modeling in order to reasonably and quickly evaluate the reserves of new investment projects in overseas oil and gas field development, and to provide a basic geological model for the formulation of a development plan. The evaluation consists of data collection, geological framework evaluation, reservoir facies and properties evaluation, and reserve calculation and risk assessment. It can be divided into two stages: geological modeling and reserve evaluation. The geological modeling stage includes three-dimensional modeling of the most probable structures, reservoir facies and properties based on data collection. In the reserve evaluation stage, the uncertainty of the geological framework, reservoir facies and properties are carried out based on the understanding of reservoir uncertainty, then the probabilistic reserve distribution is obtained and the risk of reserve is exposed. Finally, the rapid scientific reserve evaluation of the new investment projects of overseas oil and gas field development is realized. The reserve evaluation method for new investment projects of overseas oil and gas field development based on geological modeling effectively integrates the advantages of volume method and probability method, and the application example shows that the method is practical and can be applied to the reserve evaluation of overseas oil and gas fields.
