DETERMINE TOP OF OVERPRESSURE AND STRESS REGIME

Before using these tools, there are several things that must be understood:

1. Normal Shale Porosity data can be obtained from uncompacted sonic logs, laboratory data, or literature data.

2. Biot's Coefficient data can be obtained from laboratory data or literature data.

3. Bulk Density data can be obtained from RHOB logs, but must first be converted to kg/m³.

4. Shale porosity data can be obtained from DT logs.

5. Data for validating overpressure can be obtained from MDT or DST.

6. Shmin data can be obtained from Mini-frac/leak-off tests (LOT, MDT, RFT) or borehole breakouts.

7. Shmax data is obtained by using geomechanical data and rock properties.
