Sidetrack 2 coring tool controls

Sidetrack 2 coring tool controls

This was an interesting project because it had to work on the first try. The purpose of this device was to activate hydraulics on a well drilling head just at the right time. Since the unit is used on a drilling rig where each minute spend at the well testing costs a lot of money it had to work. Along the way there were many unknowns as to how well it will receive the control signals so number of activation methods were conceived.

The solution was in designing two modes. First was a data logging mode that recorded a number of sensors. The tool was lowered, the test signals were sent and the tool was pulled out of the well. The collected data were analyzed within minutes and the tool was configured in the operational mode with settings derived from the logged signals. On the second run down the well it activated.

I designed the sensor interfaces with configurable filters. I prepared the schematics, PCB, Firmware and performed a lot of testing.
