It’s simply not true that you don’t know if the oil will flow again. It will. The subsurface pressure and fluid behavior is well understood. One of the only scenarios that might lead to wells failing to flow when reopened would in wells that were freshly tracked without flowing back the frack water. In this case the frack water will soak into and damage the clay-like minerals in the rock and damage the permeability of the rock.
