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 1):
A method for discrete multi-tone, half duplex cable telemetry for a wellsite, comprising:\n generating a first portion of a message unidirectionally or bi-directionally in a first cable propagation mode; generating a second portion of a message unidirectionally or bi-directionally in a second cable propagation mode; and transmitting the first and second portions of the message unidirectionally or bi-directionally over a cable operatively coupling a surface modem and a downhole modem sequentially in a plurality of time periods across a frequency bandwidth, the downhole modem being located downhole in a wellbore, wherein any bi-directional messages are separated by a quiet time period during which no message is transmitted on any cable propagation mode; wherein the frequency bandwidth is selected by exchanging known training sequences between the surface and the downhole modems and the modems are adjusted for a given cable length, cable type, channel response, temperature and noise spectrums of the surface and downhole modems, wherein a length of the quiet time period is determined based on one or more of: a length of the cable, a time interval sufficient for a cross-talk ECHO 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.
