  • Publication number: 20230185810
    Abstract: A computer-implemented method for processing a logic rule in a graph database. The method includes obtaining a graph database comprising at least one graph, each graph of the database being represented in one or more adjacency matrices (R-Matrix), each adjacency matrix representing a group of tuples of the graph comprising a same predicate, obtaining the logic rule concluding to a head predicate, generating a virtual adjacency matrix comprising one of the one or more adjacency matrices (R-Matrix) and an entailed data matrix (E-Matrix), the virtual adjacency matrix representing the head predicate, the entailed data matrix representing a group of tuples that are computed by applying the logic rule, and receiving a query by the database using the head predicate.

  • Publication number: 20230039147
    Abstract: A method can include acquiring data during rig operations for a specified drillstring for drilling a specified borehole in a geologic environment, where the data include downhole survey data; determining a drillstring load based on at least a portion of the data; comparing the drillstring load to a plurality of modeled loads, where the plurality of modeled loads depend on the specified drillstring, the specified borehole, and at least a portion of the survey data and correspond to a plurality of different friction factor values; and, based on the comparing, estimating a friction factor value that corresponds to the drillstring load.

  • Publication number: 20220120176
    Abstract: A method can include identifying a threshold value for a drillstring off-bottom condition determination; filtering time series surface data of a post-connection drilling state of the drillstring using the threshold value to generate filtered time series surface data; and statistically determining a drillstring off-bottom condition value using the filtered time series surface data.
