Sometimes oil reservoirs have major fault lines running through them. One possible solution to accommodate for these could be to split the reservoir into un-faulted regions. Fig 1 & 2 below shows a representation of a sample of rock containing oil, which has three major faults run through it. It shows how this sample could be split up into six un-faulted regions and each of these could be converted into seperate grids.

Fig 3 & 4 below is a 3D representation of the above fractured rock matrix. It shows the 3 planes of fractures and the resulting six different matrices generated from it. Each of these individual rock matrices will be a computed seperately using octree structures.
