Data Formatting Unit
- The DFU is a downhole sonde that allows the user gapless operation when used with an X Generation TAS.
- It is located in between the X-TAS and the digitizers.
- Compatible with all Geochain digitizer modules for gapless recording
- Sim variant available (SDFU)
The DFU contains memory that stores digitizer data whilst the TAS has stopped, enabling the data to be continuous without gaps. The system shares the same x-generation unique Active Cooling System for continuous operation at 385oF/195oC and seals for 25,000psi (1700 bar) pressure rating
Extra Fucntionality if also using x-digitizers (AS-272 or AS-251)
- Facilitates both discrete buffering and formatted recording doubling the number of tools available for a given sample rate.
