IsoLoc Perforating System

 

GEODynamics IsoLoc perforating system utilizes bi-directional boosters, non-lead azide explosives, customised connectors and inserts and high velocity-low shrink detonating cord. Additionally, all GEODynamics perforating assemblies are scalloped to optimise charge performance and prevent casing damage from perforating exit hole burrs while shot phasing is designed to maintain the integrity and collapse resistance of the casing after perforating. These attributes, along with premium quality gun material and gun connectors, allow GEODynamics to deliver safe, efficient and reliable perforating solutions to our customers.

GEODynamics IsoLoc perforating system are utilized to establish annular communication between multiple casing strings. IsoLoc systems limited entry perforating charges custom designed to penetrate inner strings of casing without penetrating the outer most string or strings during P&A or squeeze cementing operations. IsoLoc perforating charges deliver large and consistent entrance holes in the casing using standard phasing for perforation distribution. IsoLoc allows access to specific annuli for the clean out prior to cement placement for zonal isolation.

With systems designed to access A, B, C and D annuli GEODynamics offers a broad range of IsoLoc solutions for 3 3/8” 12 spf, 4 5/8” & 5 1/8” 16 spf and 7” 12, 15 and 20 spf gun systems.

IsoLoc charges are controlled performance perforating charges finely tuned for very specific applications. Data such as casing weight and grade, fluid type, and weight are critical to a successful IsoLoc operations.
