axis-symmetric handling of Horizontal wells?

Post by Hector » Tue Oct 29, 2002 9:57 am

Hello out there,

we would like to analyse pressure data gained in response to the drilling of a release well in a clay soil. However the drillings are not vertical but tilted, some almost horizontal.

Formally a rotational symmetric domain is required to model the pressure propagation to the well boring. Since the symmetry axis does not coincide with the gravity -axis, a tilted system should be set up in which the two components (sinus and cosinus) of the gravitational acceleration have to be considered

I have heard of such FE-systems, especially in the field of hill-slope hydrology, where people build up their (regular) meshes in the x/z coordinate system and then consider the inclination through the components of the gravity.

Would this concept also work for tilted rotational symmetric systems.
Could this be an option for HYDRUS2D?

Any hints appreciated

Hector
