Abstract:
Methods and systems for multiple carrier frequency, half duplex cable telemetry for a wellsite. The methods involve generating a first type of bi-directional message in a first propagation mode, generating a second type of bi-directional message in the first propagation mode and in a second propagation mode, transmitting over a cable operatively coupling a surface modem and a downhole modem the first and second types of bi-directional message sequentially in a plurality of time periods across a single frequency bandwidth, and separating each of the first and second types of bi-directional message from a most subsequently transmitted one of the first and second types of bi-directional message by a quiet time sample during which no message is transmitted.

Claim (Index 12):
A system for discrete multi-tone, half duplex cable telemetry for a wellsite, comprising:\n a surface acquisition unit operatively coupling to a surface modem that generates one or more downlink messages in a first propagation mode for transmission in a downhole direction; a downhole modem that generates one or more uplink messages in the first cable propagation mode and in a second cable propagation mode for transmission in an uphole direction; a downhole toolstring comprising one or more downhole sensing tools that obtain measurements relating to at least one of borehole characteristics and formation characteristics, the downhole toolstring operatively coupled to the downhole modem via a toolbus; and a cable electrically coupling the surface modem and the downhole modem; wherein the downlink and uplink messages are transmitted sequentially in a plurality of time periods across a selected frequency bandwidth, wherein each of the downlink and uplink messages are separated from one another by a quiet time sample during which no message is transmitted in either the downhole direction or the uphole direction; wherein a length of the quiet time sample is determined based on one or more of: a length of the cable, a time interval sufficient for a cross-talk echo between cable propagation modes to dissipate, and a variable user input, so as to allow sufficient time for the residual energy caused by a message most recently transmitted, in a direction along the wellbore, to dissipate before another message, transmitted in the other direction along the wellbore, is received.
