  • Publication number: 20210156246
    Abstract: A combined telemetry system that can be used while drilling a wellbore consists of a multi-hop telemetry method and a single-hop telemetry method combined in parallel. The multi-hop and single-hop methods can be operated in parallel, for example, so that each telemetry method caries data concurrently from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly. The multi-hop and single-hop methods can also be operated in series, for example, so that data from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly are first carried with the single-hop telemetry method and then transferred to the multi-hop telemetry method at one or more node(s) close to the surface. Preferably, the multi-hop telemetry method can also carry data from along-string sensors. Another combined telemetry system that can be used while drilling a wellbore consists of two single-hop telemetry methods combined in parallel.

  • Patent number: 10997078
    Abstract: A method for accessing a non-volatile memory comprises that an NVM controller receive a first access request from a processor and determines whether the first access request is used to access a page table. If the first access request is used to access the page table, the NVM controller obtains an AIT entry by reading a page table entry indicated by the first address information and caches the AIT entry to an AIT cache. The NVM controller monitors access of the processor to the page table, prefetches the to-be-accessed AIT entry.
