The plan view shows a typical 5-spot pattern centered on stimulated well IR_1_5474. The stimulated (dilated) pre-existing fractures are colored according to their rock type (see legend).
The 3-D view shows the pre-existing fractures that dilated (opened-up) during the stimulation events. The red colored features represent newly created fractures.
Modelling indicates pre-existing fractures are stimulated in preference to creating new fractures.
