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 8):
A system for discrete multi-tone, half duplex cable telemetry for a wellsite, comprising:\n a surface modem that generates one or more downlink messages in a first propagation mode for transmission in a downhole direction; one or more downhole tools that obtain measurements relating to at least one of borehole characteristics and formation characteristics, the one or more downhole tools coupled by a toolbus to a downhole modem, the downhole modem generating one or more uplink messages in the first propagation mode and in a second propagation mode for transmission in an uphole direction; and a cable electrically coupling the surface modem and the downhole modem; wherein the downlink and uplink messages are transmitted over the cable sequentially in a plurality of time periods across a single frequency bandwidth, wherein 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 or 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.
