Downhole Controller XTU ULTRALINK 80674 XTU PSU Telemetry PCB

120-300VDC

ULTRALINK MODEM

ULTRAWIRE PSU (SMPS) +5 V

• Modem to surface, ULTRALINK • Uplink at 50, 75 or 100kb/s (option of 200kb/s) • Downlink at 300b/s every 15secs – If no response, reduces telemetry rate Modem to sensors, ULTRAWIRE • XTU on power up ‘sees’ what tools below >170V cablehead voltage

15-18VDC CONTROLLER

• Creates “Service Table” Lowest tool address first, maximum of 62 tools

ULTRAWIRE MODEM

80672 XTU Processor PCB ULTRAWIRE

(subject to power requirements)

Power supply • Converts high voltage DC, 200V, from the Ultralink to low voltage DC, 18V (17.8V), for the Ultrawire. Current consumption at 200V 20mA (no Load), 28-30mA (running SCT) • XTU002 has HVOLTS & ITEMP curves, max 200°C (392°F) sensor by PSU transformer

Sondex tool addresses

Ultrawire The Ultrawire™ protocol includes commands for: • data acquisition • tool configuration • tool software and parameter download • control of motorised tools • bandwidth sharing with other nonUltrawire™ modulation schemes over the same monocable bus.

Ultrawire Memory The Ultrawire™ memory system

• Data is transmitted via the Ultrawire™ toolbus to the memory tool at the top of the toolstring. • Data is stored in non-volatile flash memory chips under the control of a downhole processor. • 128MB of memory. (UMT007 = 1GB) • The tool supports all the standard Ultrawire™ tools.

ULTRALINK & ULTRAWIRE Amplitude approx. 4 – 5 Vp/p. Data pulse should return to baseline, max 20% overshoot permissible. Adjust panel Equaliser for best compromise between pulse overshoot and low frequency ‘wobble’ on the signal baseline. Sour cables (H2S) • overshoot can be excessive, can not equalise • modify panel with kit number KITU-32-ULP DRS (daughter card to the back of the main equaliser board, and software)

Equalization

Correct

Equalization adjusts the amount of high frequency boost applied to the uplink signal. Oscilloscope is strongly recommended

Under equalised

Over equalised
