Abstract
The present disclosure provides several methods for selecting and transmitting information from downhole using more than one channel of communication wherein data streams transmitted up each communications channel are each independently interpretable without reference to data provided up the other of the communications channels. Preferred embodiments incorporate the use of a combination of at least two of mud-based telemetry, tubular-based telemetry, and electromagnetic telemetry to achieve improved results and take advantage of opportunities presented by the differences between the different channels of communication.
Claims (14)
1. A method for communicating data in a wellbore having a drill string through which drilling mud flows during drilling operations, comprising:
using a first telemetry transmitter coupled to the drill string to transmit a first data stream through a first communication channel;
using a second telemetry transmitter coupled to the drill string to transmit a second data stream through a second communications channel;
wherein said second data stream comprises selected duplicated elements of said first data stream and wherein each data stream and such elements are each independently interpretable without reference to data provided up the other of the communications channels.
using a first telemetry transmitter coupled to the drill string to transmit a first data stream through a first communication channel;
using a second telemetry transmitter coupled to the drill string to transmit a second data stream through a second communications channel;
wherein said second data stream comprises selected duplicated elements of said first data stream and wherein each data stream and such elements are each independently interpretable without reference to data provided up the other of the communications channels.
2. The method of claim 1 wherein the method is for communicating data is a wellbore having a drill string forming a tubular communications channel and through which drilling mud flows during drilling operations forming a mud communications channel, wherein:
the first telemetry transmitter is a first acoustic transducer; and the second telemetry transmitter is a second acoustic transducer.
the first telemetry transmitter is a first acoustic transducer; and the second telemetry transmitter is a second acoustic transducer.
3. The method of claim 2, wherein the first acoustic transducer is a tubular-based telemetry device and the first communications channel is the tubular channel;

9. The method of claim 3, wherein the first stream of data comprises the majority of a selected stream of formation evaluation data being collected.
10. The method of claim 1, wherein the first stream of data comprises the majority of the formation evaluation data being collected.
11. The method of claim 1, wherein the selected duplicated elements of said first data stream comprise a sampling of elements of said first data stream.
12. The method of claim 6, wherein the sampling of elements is one out of every ten elements.
13. The method of claim 1, wherein the selected duplicated elements of said first data stream comprise a duplicate of every tenth element of said first data stream.
14. The method of claim 1, wherein said first data stream comprises at least two multiplexed data streams;
wherein said second data stream comprises at least two multiplexed data streams;
wherein a first of the multiplexed streams of the second data stream comprises selected duplicated elements of a first of the multiplexed streams of the first data stream; and wherein a second of the multiplexed streams of the first data stream comprises selected duplicated elements of a second of the multiplexed streams of the second data stream.
wherein said second data stream comprises at least two multiplexed data streams;
wherein a first of the multiplexed streams of the second data stream comprises selected duplicated elements of a first of the multiplexed streams of the first data stream; and wherein a second of the multiplexed streams of the first data stream comprises selected duplicated elements of a second of the multiplexed streams of the second data stream.
