Discussions about integrated resource evaluation are recently mentioned by domain researchers and energy companies, which are paying more attention on the development of integrated evaluation software. However, there does still exist different ways to demystify techniques about integrated resource evaluation. This paper presents experienced understandings about it in three perspectives : integrated resource management, integrated assessment process and integrated software implementation. As well, they are guiding the development of our integrated evaluation software, PetroV. From importing, cleaning and normalizing plenty of magnitude of accumulation information to the delineation of hierarchical evaluation units, integrated resource management embraces resource evaluation with series of resource portfolio, namely prospects, against multiple engineering and marketing scenes, benefits with resource evaluation, exploration planning and marketing decisions etc in full scale way, and expresses its full edge capability of investment management. Tracing the full cycle fluctuating wave of resource and reserve, integrated assessment process unifies kinds of evaluation activities against different geological units stepping from a basin, to a play, to a trap, to a pool, even to a production well, and sets up an needed, adjusted and traced enable assessment process. The implementation of integrated software shields from heterogeneous distribution environment under the help of domain middleware and shares a common language among assessments of a basin, a play, a trap etc with ST based KIDA modeling mechanism in order to seamlessly concatenate assessment phases. Having being benefitted from the advancement of software and data integration techniques as E&P information technique solution, experienced by multiple resource evaluation rounds and enlighten by the latest advancement of information technique, it is time to let integrated resource evaluation play more for us.
