The GRT-2 HP Gamma Ray Tool is a standard scintillation detector type production gamma ray tool housed within an in-line ASR-1 body. This arrangement allows the GRT-2 to be inserted anywhere within an analogue ASR tool string or between the wireline adapter and TAS section within a Geochain^TM string.

 

• 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 replaces the now obsolete GCM box, which interfaced the DCP-1 with the GSP.
