Application of Multiple-Point Geostatistics in Sedimentary Facies Modeling

Abstract:

Compared with 2-point variogram-based geostatistics, multiple-points geostatistics is able to delineate reservoirs of complex spatial architecture or geometries more accurately. Multiple-point geostatistics stochastic simulation is introduced to apply on delta reservoir modeling by taking 2Sa block in a certain oil field at BeiBuWan basin for example. At first, the training image of 2Sa block deposited in delta frontier of study area is established by digitizing sedimentary facies and then facies model of 2Sa block is created with the method of multiple-point geostatistics. The result indicates that facies model simulate the sedimentary microfacies space distribution as well as distribution law of sandbodies, which provides a guiding significance for predicting the distribution of effective sand-body in the study area.
