2.0 Each GR one Negative and one Positive, 2.0 Each Motorized ejector (30cc) with funnels, 2.0 Each CCL’s all 1 3/8” OD.

Gamma Ray tools can be switched to run an add on temp sensor when not running Caliper. Temp Sensor or Caliper are NOT included!

1.0      Tool string – Electrical checks & Operational Advice

1 3/8 Tracer Tool String Tool string operating procedures:

• Firstly, the tool can be stacked in multiple configurations, by default configuration the Neg-Pulse GR must be on top of the Pos+Pulse GR
o CCL, Ejector, Neg-Pulse, Pos+Pulse, Temp
o CCL, Neg-Pulse, Ejector, Pos+Pulse, Temp
o CCL, Neg-Pulse, Pos+Pulse, Ejector, Temp

• The head voltage for the Single Gamma Ray Mode is 70vdc

• The head voltage for the Dual Gamma Ray Mode is 90vdc

• Tool GR current is 50mA for each gamma ray sensor.

• Tool string current for both dual and single Gamma Ray is 100mA when in GR mode.

• To switch into Temperature mode, raise the head voltage above 125vdc, then back off the voltage to 100vdc. Tool string will remain in Temperature mode until a head voltage above a Negative 35vdc is applied to the tool string, including when the ejector is motored.

• Tool string current is around 25mA when in Temperature mode.

• The Ejector operates with a Negative 100vdc applied to the head of the tool string. With a 60-100mA current range (depends on the direction of the piston).

• Use CAUTION when separating tools vertically after logging the well. If a wet sub is not used on each tool then the fluid running down the string will drip directly on the electronics. The contact that is seen looking down into the housing is the top of the electronics’ chassis. The fluid will short out the electronics or cause the chassis to become welded to the pressure housing.
