... to bullhead diverter treatments that re-stimulate existing perforations and these are no longer a "best practice" in most cases (Barba 2024). Once mechanical isolation is employed and legacy perforations are sealed off permanently the treatment becomes a "recompletion" of previously unstimulated portions...

.... For the ultrasonic scans, a casing-wall loss percentage threshold was employed as the primary plug performance metric. When testing alternative plug options, static plug pressure tests were conducted at the surface prior to perforation. Drillout times were also assessed. Results/Observations/Conclusions...

... in 2021. The CiC refracturing method was to cement a 3.5-in. liner in the legacy 5.5-in. casing, where the original perforations were sealed, and new plugging and perforating (P-n-P) operations were performed in the reconstructed wellbore. During the BH refracturing, the treating pressure gradually...
