Research on variogram analysis method for 3D modeling of sandstone reservoir

Methodology for Variogram Interpretation and Modeling for Improved Reservoir Characterization

The variogram is a critical input to geostatistical studies. It is the most widely used tool to investigate and model spatial variability of lithofacies, porosity, and other petrophysical properties. In addition, 90% of geostatistical reservoir characterization studies use variogram-based geostatistical modeling methods. Furthermore, the variogram reflects our understanding of the geometry and ...

Reservoir Characterization of Pennsylvanian Sandstone Reservoirs

Study on Stochastic Flow in Low Permeability Sandstone Oil Reservoir

Reservoir porous medium is random, in terms of oil and gas for low permeability reservoirs. Consider the random nature of the reservoir will enable to improve the accuracy of numerical reservoir simulation. Based on extensive research, for the stochastic nature of the reservoir from the two aspects of physical simulation, numerical simulation, the relevant international studies were reviewed. T...

Compaction Localization in Porous Sandstone: Implications for Reservoir Mechanics

Compaction of porous rocks can occur in two modes: uniform and localized. Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly...
