One of the foundations of LithoTect is its geologically accurate representation of subsurface rock structure. Knowing the configuration of subsurface structures is clearly important - few wells have been drilled without a structure contour map - but the subsurface geometry also defines attributes such as dip and curvature that can influence reservoir properties.

Subsurface reconstruction comprises 3 distinct interpretation elements:

• Interpolation uses known horizons, perhaps from good seismic reflections or well penetrations or from outcrop information, along with a known rule or estimator, to constrain the "in-between" horizon configurations; it will also be shown that two or more separate horizons can allow interpolation of the intervening geometry to whatever scale of resolution is desired.
  

• Projection takes a known or interpolated horizon and represents additional layers using a defined rule or correspondence.
  

• Extrapolation is truly a journey into the unknown, with no rules or constraints; in general, section and 3D model reconstruction attempts to remain within the arena of interpolation and projection.
