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.
