Intersect a trajectory with the set of simulated fractures
fracsimu.to.well(fracsimu, well.line = NA, permtab=NA)
fracsimu |
A |
well.line |
The trajectory that must be intersected with the set of fractures. This argument must be provided as a matrix with two columns (i.e. X and Y) and as many rows as there are end points along the trajectory. |
permtab |
Array of permeabilities assigned to each fracture family. The first value is assigned to the main fault (family 0); the second value is assigned to fractures belonging to the first family, and so on. If this argument is not provided, the starting and ending permeability values are set to 0. |
As a result this function returns an enhanced trajectory. This trajectory is the constitued of the list of the intersections of the initial trajectory with the set of fractures. It corresponds to a matrix with 8 columns:
Col1 X-coordinates of the end points of the new trajectory
Col2 Y-coordinates of the end points of the new trajectory
Col3 Rank of the fracture
Col4 Rank of the segment within the fracture
Col5 Family to which the fracture belongs
Col6 Value of permeability at the intersection of the fracture with the trajectory, or perturbed permeability
Col7 Value of permeability along the fracture, after a distance larger than the range, or stationary permeability
Col8 Range: Distance (counted along the fracture) beyond which the permeability is set to its stationary value
The rank of the fracture (and the rank of the segment) are left equal to 0 for the beginning and end of the initial trajectory.
