This tutorial walks through the complete stress-calculation workflow in the WellCAD Geomechanics Workspace. From raw logs to a full stress envelope. Using a dataset with sonic, resistivity, density, gamma ray and MDT pressure points, we build stress curves step-by-step and validate them against measured data.

You will learn how to:

• Set up the geomechanics workspace and depth reference.
• Build a composite density curve (measured, Gardner-derived & extrapolated) to calculate overburden stress.
• Identify shale intervals and pick normal compaction trend lines for sonic and resistivity.
• Apply Eaton’s method to derive pore pressure and calibrate interactively with field data.
• Calculate minimum and maximum horizontal stresses using mechanical properties and LOT data.

Through zoning, interactive curve adjustment and calibration against real measurements, WellCAD enables a transparent and robust approach to subsurface stress modelling delivering a reliable stress profile ready for borehole view and operational decisions.
