The Custom Equation Editor is a powerful and flexible feature within WellCAD’s Geomechanics Workspace, designed for professionals who require complete control over their analytical workflows. It allows users to extend the default library of equations by creating and integrating custom or empirical formulas derived from technical publications or internal expertise. This capability is especially valuable when standard methods fail to deliver accurate correlations, enabling users to refine interpretations and achieve more reliable results tailored to specific lithologies or datasets.

Through an intuitive interface, users can define new parameters, document their sources, validate equations, and instantly visualise enhanced outputs directly within the log display. This results in measurable improvements in data fit and interpretation quality, empowering advanced users to optimise complex geomechanical analyses with greater confidence. The Custom Equation Editor further reinforces WellCAD’s position as a highly adaptable platform, supporting precision-driven decision-making and advanced technical innovation in subsurface evaluation.

The example presented in the video demonstrates the reconciliation of dynamic Poisson’s ratio derived from logs against core measurements, highlighting how default sandstone methods may fail to achieve reliable results. It then illustrates how users can create a new parameter by defining its name, group, description, and associated method sourced from published technical literature, ultimately achieving a significantly improved correlation and more accurate geological insight.
