Questions?

COHIBA is a fast and accurate tool for making deterministic and stochastic surfaces. It is used by oil companies for surface modelling on oil fields all around the world. Since the first release in 2007 COHIBA has evolved significantly and now exhibits advanced features like the ability to predict optimal well trajectories and to update surfaces directly in the structural model.
