How do Teleperfs address risks associated with traditional perforating?
Teleperf technology addresses the following risks to well productivity posed by perforating in unconsolidated formations: • Area open to flow Generally, well productivity is directly related to the area of flow through a perforation tunnel. Greater area of flow means greater well productivity. If perforation debris, fractured and compacted zones or broken pieces of formation become lodged in the tunnel, they can block the available flow area. • Effect of near-wellbore damage Drilling and completion fluid-induced damage can be extremely tough to remove. Deep penetrating perforating charges can bypass the formation damage, but the perforation tunnels are more susceptible to skin damage and fines infiltration. Both of these can adversely affect well productivity. • Effect of perforation damage Flow restrictions caused by crushed zonal rock can increase skin values, particularly over the extended lifetime of a well.
