Abstract
A method and system are described for communicating within a system, which may be along tubular members. The method includes constructing a communication network for tubular member, such as a wellbore accessing a subsurface region or a pipeline, and using the communication network in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
Claims36
A method of communicating data among a plurality of communication nodes, the method comprising:
- obtaining data for a system;
- creating a communication network based on the obtained data, wherein the communication network includes a plurality of communication nodes, wherein the creation of the communication network comprises selecting one of one or more frequency bands, one or more individual tones, one or more coding methods, and any combination thereof;
- profiling the communication network in a testing unit to obtain diagnostic telemetry data;
- configuring the communication network at least partially based on the diagnostic telemetry data;
- installing the communication network associated with the system into a wellbore;
- communicating between the plurality of communication nodes in the wellbore, based on multiple frequency shift keying (MFSK) telemetry, to perform operations for the system, the MFSK telemetry using a number of tones;
- and
- adjusting frequencies used in the MFSK telemetry by
- dividing a range of possible reception frequencies into a number of sections;
- combining similar reception frequencies into one of the number of sections, thereby forming a
- combined frequency in each of the number of sections, wherein all frequencies within each
- combined frequency is classified as a single frequency;
- determining whether each combined frequency satisfies a signal strength threshold;
- and
- selecting a number of combined frequencies that satisfy the signal strength equal to the
- number of tones used by the MFSK telemetry;
- the method further comprising:
- i) monitoring the communication network for an event;
- ii) modifying the communication network if the event is detected;
- iii) continuing the communicating between the plurality of communication nodes if the event is not detected;
- and
- repeating steps i) to iii) until the hydrocarbon operations are complete.
A system for modeling communications between a plurality of communication nodes along one or more tubular members, the system comprising:
- a testing unit comprising:
- a housing with an interior region formed by the housing;
- one or more tubular members disposed within the housing;
- and
- a communication network disposed within the housing, wherein each of a plurality of communication nodes are disposed along the one or more tubular members and spaced apart along the one or more tubular members at a distance greater than one foot, each of the plurality of communication nodes being configured to exchange data using multiple frequency shift keying (MFSK) telemetry, and wherein the communication network is established by selecting one of one or more frequency bands, one or more individual tones, one or more coding methods, and any combination thereof;
- wherein frequencies used in the MFSK telemetry are configured to be adjusted by dividing a range of possible reception frequencies into a number of sections;
- combining similar reception frequencies into one of the number of sections, thereby forming a combined frequency in each of the number of sections, wherein all frequencies within each combined frequency is classified as a single frequency;
- determining whether each combined frequency satisfies a signal strength threshold;
- and
- selecting a number of combined frequencies that satisfy the signal strength equal to the number of tones used by the MFSK telemetry;
- and
- wherein each of the plurality of communication nodes are configured to:
- i) monitor the communication network for an event;
- ii) modify the communication network if the event is detected;
- and
- iii) provide a notification if the event is detected.
