Abstract
A method and system are described for wirelessly communicating within a wellbore. The method includes constructing a communication network (e.g., which uses aliased signals as part of the configuration) for a wellbore accessing a subsurface region and using the communication network in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
Claims44
A method of communicating data among a plurality of communication nodes, the method comprising:
- disposing the plurality of communication nodes within a wellbore;
- creating a communication network, wherein the communication network comprises the plurality of communication nodes, wherein each of the plurality of communication nodes is configured to utilize aliased frequencies in one or more signals to communicate between two or more of the plurality of communication nodes;
- configuring the plurality of communication nodes;
- communicating operational data between the two or more of the plurality of communication nodes, wherein the communicating the operational data is at least partially based on the one or more signals in which the aliased frequencies are utilized to communicate the operational data;
- and
- performing operations based on the operational data;
- receiving the one or more signals in the two or more of the plurality of communication nodes;
- determining whether to perform a signal confirmation on the one or more signals received in the two or more of the plurality of communication nodes;
- performing the signal confirmation on the one or more signals based received in the two or more of the plurality of communication nodes on the determination that the signal confirmation should be performed and then decoding the one or more signals received in the two or more of the plurality of communication nodes;
- and
- decoding the one or more signals received in the two or more of the plurality of communication nodes without performing the signal confirmation on the one or more signals received in the two or more of the plurality of communication nodes if the determination is to not perform the signal confirmation.
A system for communicating along one or more of a plurality tubular members comprising:
- the plurality of tubular members;
- a communication network coupled to the one or more of the plurality of tubular members, wherein the communication network comprises a plurality of communication nodes disposed within a wellbore, wherein each of the plurality of communication nodes are configured to:
- communicate operational data between two or more of the plurality of communication nodes, wherein the communication of the operational data is at least partially based on aliased frequencies;
- and
- perform operations based on the operational data
- receive one or more signals;
- determine whether to perform a signal confirmation on the one or more signals;
- perform the signal confirmation on the one or more signals based on the determination that the signal confirmation is to be performed and then decode the one or more signals;
- and
- decode the one or more signals without performing the signal confirmation on the one or more signals if the determination is to not perform the signal confirmation.
