Geomechanics modules
Geomechanics modules comprise a host of intuitive, easy-to-use software tools for optimal decision making and accurate assessment of geomechanical risks. There are instruments for building a mechanical earth model, getting insight into stress state and calculating wellbore stability; tools for quantifying formation overpressure, understanding allowable bottom hole pressures to prevent from sanding and assessing faults’ stability.
Advanced Pore Pressure
Determining the formation pressure in overpressured formations
- Defining the top of overpressure
- Pore Pressure Prediction at planned well
- Determination of the required mud weight to prevent formation kick
- Well design optimization based on pore pressure and fracture pressure
- Analysis of pore pressure in realtime based on LWD
1D Geomechanics
Calculating elastic and strength properties, building the profiles of pressure and stresses
- Calculation of dynamic and static Young’s modulus, Poisson’s ratio, Biot coefficient
- Defining the rock compressive and tensile strengths
- Calibrating log data to core measurements
- Estimating the total and effective formation stresses
- Defining the stress direction
Wellbore Stability
Calculating the safe mud window based on 1D geomechanical model

Sanding Control
Modeling of Sanding onset
- Defining the probability of solids production
