Geologic interpretations are the basis of most exploration workflows, whether building a 3-D framework, a geocellular model, or modeling HC basins and estimating HC reserves. All these workflows rely on the most realistic and accurate interpretation in order to produce high-confidence results.

Join us to hear from Catalina Luneburg, founder and director of TerraEx Group and specialist in the validation of HC basins and structural geology modeling about the importance of balancing modeling interpretations.


Geologic interpretations are the basis of most exploration workflows, whether building a 3-D framework, a geocellular model, or modeling HC basins and estimating HC reserves. All these workflows rely on the most realistic and accurate interpretation in order to produce high-confidence results.

Despite the importance, this step is often undervalued. We mostly focus on honoring seismic reflectors and well data without adequately testing the geometrical and/or mechanical validity of the regional model. This becomes especially critical in poor or missing data areas, where we interpolate between existing data points using our best logic and geologic understanding but not applying rules of geometrical compatibility and volume preservation. The process of balancing and restoration will reveal inconsistencies and allow to correct the compatibility problems using techniques of line-length and area-balancing.

Interpretation validation should be a standard component of our best practices and QA process. Incorporated into our workflows from the beginning on, it will significantly save time and cost down the road.
