APS's SureShot natural gamma sensor controller board upgrade

Thursday, May 9, 2013

APS Technology, Inc. announced the general availability of an upgrade path for their natural gamma sensors.

APS Technology has developed a new gamma controller board that is "plug-and-play" with all existing gamma sensors. This new PCB has undergone APS's rigorous HALT/HASS qualification, 1,000 hours at 175C life testing and has logged more than 1,000 downhole hours of field testing.

The new gamma controller offers two distinct advantages over the current board:

The new board has built-in accelerometers that measure axial and lateral vibration. Peak axial shock, lateral shock, and temperature data are stored in memory every 5 minutes up to 5,000 hours. Information on the service history of the tool is also stored in memory.

This lifetime log will provide valuable information to evaluate the health of the tool, and to develop preventative maintenance cycles based on the actual operating environment over time rather than total downhole hours alone. Vibration measurements can also be used to justify claims for repairs that are a result of out-of-spec drilling conditions.

Gamma module environmental data can be downloaded using APS's MWD Master Interface software. Future APS software releases will run the downloaded data through an 'Accumulated Damage Model' to enable Condition-Based Maintenance scheduling based on the gamma module's operating history.

The new controller board also draws 77% lower current than the previous-generation board, which translates into a 15% increase in battery life on a DG string.

Gamma tools can be upgraded with the new gamma controller at any of APS's repair and maintenance facilities.
