Gamma Gun - Scintillation

The Gamma Gun - Scintillation tool utilizes a ruggedized thallium doped sodium iodide NaI(Tl) crystal detector with a 1” diameter x 3” photo-multiplier tube (PMT), shock mounted inside the tool housing to provide maximum survivability in a perforating environment.

The shock mounted dual magnet center coil Casing Collar Locator (CCL) provides maximum sensitivity for many ranges of casing sizes. Gamma Ray-CCL data is available to surface with any NIMS system or computer logging system capable of processing standard pulse data. Internal shooting circuitry enables operation of the Gamma Ray-CCL with positive voltage and shooting with negative voltage. The dual fire system allows for shooting on both + or - DC, while maintaining the maximum safety possible.

The gun detonator is held shorted to ground until a preset line voltage is reached. The detonator then is open-circuited until a second preset voltage is reached, where firing voltage is then switched to the gun. This feature is important for select fire or multiple-gun firing with one trip into the well bore.
