The GRT-2 EHP has been built and tested for 30,000 psi operation. This variation offers a heavier weight, 3 1/4” diameter and is optimised for the Geochain EHP system.


  • Surface Control – The Geochain System Panel (GSP) with an inbuilt Gamma Control Module (GCM) is required for all gamma tool systems. For analogue systems a Dual Control Panel (DCP-2) is required to power the tool. This new panel system has replaced the now obsolete GCM box, which interfaced the DCP-1 with the GSP.
