As the search for energy resources goes deeper under the sea and into ever more challenging environments, exploration and production companies face greater uncertainties about subsurface structures and their behaviour. The lack of a clear picture of the subsurface presents a high risk of well failure.

Modelling the subsurface more accurately has been a challenge but novel approaches combining imaging data with numerical models have shown great promise. Among them is the mechanical earth model (MEM) used by Chevron.
