Voltage Protection Module


VOLTAGE PROTECTION MODULE

VPM-G, VPM-E

The Voltage Protection Module (VPM) is a surface controlled “electrical switch” that provides an additional level of safety when conveying perforating guns or other ballistic devices with the PowerTrac systems. In the safe mode (switch in open position), it ensures no current is available at the ballistic device. In log/fire mode (switch in closed position) correlation tools can be powered and ballistic devices fired. The switch position is continuously monitored and fed back to surface.

APPLICATIONS

In highly deviated or horizontal wells, tractor conveyance of:

  • Perforating guns
  • Pipe severing tools/back off string shots/tubing punchers
  • Explosive plug setting

 

FEATURES

  • Combinable with passive and powered CCLs
  • Standard GO type head connections
  • Can be run with both positive and negative polarity fired perforating guns
  • Compliant with API RP67
     

BENEFITS

  • QHSE; general perforating safety
  • Improved operational efficiency
