CPC E21B 47/13 (2020.05) [H04L 12/40 (2013.01); E21B 47/18 (2013.01)] | 5 Claims |
1. A method, comprising:
detecting a failure has occurred in a bus section in a tool string used in a bottom hole assembly (BHA) positioned in a borehole; and
in response to detecting the failure,
isolating the bus section by disconnecting the bus section at a first node of the tool string from a first side of the bus section and disconnecting the bus section at a second node of the tool string from a second side of the bus section that is below the bus section relative to the surface of the borehole, wherein isolating the bus section creates a first sub-bus on the first side comprising the first node and a second sub-bus on the second side comprising the second node;
operating the first sub-bus independently of the second sub-bus;
communicating the signals from the first sub-bus to the surface of the borehole with a first telemetry; and
communicating the signals from the second sub-bus to the surface of the borehole with a second telemetry.
