Method | Advantages | Limitations |
Statistic of Measured Data (Database) | Can be used to analyze a large amount of data quickly and efficiently. | Results can be affected by outliers or incorrect data. |
Core Discing | Can be used to determine rock properties such as strength and stiffness. Operated at 10-3 m3 rock volume. | Sample size is limited and may not be representative of the entire formation. |
Borehole Breakouts | Can be used to determine the orientation of stress in the rock surrounding the borehole. Operated at 10−2 - 102 m3 rock volume. | Results can be affected by borehole deviation and the presence of drilling-induced fractures. |
Relief of Large Rock Volumes (Back Analysis) | Can be used to determine the location and size of large rock volumes. Operated at 102 - 103 m3 rock volume. | Results can be affected by the accuracy of the data and the assumptions made during the analysis. |
Acoustic Method (Kaiser Effect) | Can be used to determine the mechanical properties of rock. Operated at 10−3 m3 rock volume. | Results can be affected by the presence of fluid in the pores of the rock. |
Strain Recovery Methods | Can be used to determine the deformation of rock. Operated at 10−3 m3 rock volume. | Results can be affected by the accuracy of the data and the assumptions made during the analysis. |
