Domain: Geological Modeling
Product: Kine3D™



Key exploration and production decisions are made on the basis of a numerical model of the subsurface, integrating all the data and knowledge that have been collected and interpreted. Geoscientists focus on constructing realistic models to represent the characteristics of their reservoirs, in order to understand risk and uncertainties, and to have the best estimate of hydrocarbons in a field. To do this, they need to understand the past and the basin’s evolution over time.

In this presentation, we will discuss 3D restoration: Why we need it, how it works, basic geomechanics concepts to be aware of, UVT technology and the tetrahedral grid, the Kine3D-3 workflow, outputs, and methods for volumetric restoration.

In structural geology, 3D restoration or palinspastic restoration is a technique used to progressively undeform a geological model in an attempt to learn more about the tectonic events that affected an area. It is also used to provide insights into the paleo-geometry of earlier stages of a stratigraphic sequence.

3D restoration can help us determine in a stratigraphic sequence, the rock movement from the moment of deposition until the current time, to give us an idea about paleo-geometry.  The first step is "unfaulting", followed by an unfolding of horizons. The reconstruction of a field enables us to obtain information about their internal deformation; then, the Green Lagrange strain property, dilatation and direction of the main strains can be extracted from the geologic model.

This is important to oil and gas E&P projects, because it enables the geoscientist to:

  • Validate the structural model restoration and highlight possible errors in the interpretation.
  • Obtain paleo-bathymetry, used in the simulation of depositional processes.
  • Understand tectonic events and the reservoir’s current configuration.
  • Estimate the deformation in a stratigraphic unit. The strain tensor and Stress-dilatancy are good indicators of fractures.
  • Understand hydrocarbon migration and the maturation model.
