Novel perforating system results in improved perforation for sand management
If a completion is a candidate for sand management, a new gravity-force-oriented perforating strategy can eliminate traditional sand-control treatments. If the perforations are oriented in the maximum-principle-stress plane, the perforation tunnels usually will be more stable than perforations placed away from this preferred stress plane. A new perforating system was used in a North Sea field and resulted in a 37,600-BOPD sand-free production rate. The new gun system can be conveyed on wireline or coiled tubing (CT) and also can be used in conventional tubing-conveyed perforating (TCP) applications.
