Building 3D streamlines in gOcad

 abstract = { Streamline technique are widely used in many reservoir engineering applications. The streamline technology
consists in decomposing a 3D domain into a number of one-dimensional lines along which complex
calculations (fluid flow, diffusion, thermal evolution) are done. The streamline approach offers substantial
computational efficiency and numerical accuracy compared to traditional finite-element methods
because it transforms a 3D diffusive problem into several 1D problems. Two methods were investigated
to build a set of streamlines from a vector field sampled at grid nodes (SGrid or Voxet). The first one is a
particle tracking algorithm based on a Runge-Kutta interpolator. The second method consists in using a
DSI interpolator with a constraint parallel to velocity vector field. A 1D explicit finite-differences scheme
simulator is then used to characterize compositional solution, saturation, or temperature evolution of a
fluid along streamlines at each time step. The full 3D solution is then mapped onto the initial grid from
the streamlines. This approach was validated on simple cases for which analytical solutions are known.
This technology has been used to estimate the production temperature of the futur geothermal exchanger
at Soultz, France. },
