unless the relief wells further compromise the defective strata...
relief wells can collapse...especially since they are drilled as deviated wells....over 5 degrees past vertical.
Relief wells can be truly horizontal or anything inbetween...and then when it zeros in on the bad wellbore...it could make it worst...
risky risky business
Do they know where the defective strata is and are the relief wells going to tap in below that area?
