Progress and prospect of multiple-point geostatistics

The paper summarizes the progress of multiple point geostatistics. First the origin of multiple point geostatistics is introduced and the theories of three main multiple-point geostatistic methods are analyzed. Then, the development status is concluded in three aspects. Firstly, in real reservoir modeling domain, the modeling environment is from fluvial to fan facies; the modeling content is from reservoir architecture to reservoir petrophysical property; the modeling scale is from large geologic deposits to micro pores and throats; the modeling region is from geological modeling to geological statistic inversion. Secondly, in integrating multi-disciplines modeling domain, there are three methods for integrating seismic data. Thirdly, in modeling methods domain, there are some improvements and new methods such as PRTT and the Growthsim. Based on the analysis of the development of multiple point geostatistics, the paper points out that the training image, data integration and modeling coupration are the main a
