A system comprising: a processor; memory accessible by the processor; a network interface; and processor-executable instructions stored in the memory to instruct the system wherein the instructions comprise instructions to: receive first time series data, i.e. data with respect to time, from a first source associated with a drilling operation for a borehole; receive second time series data from a second source associated with the drilling operation for the borehole; compute a similarity metric based at least in part on a portion of the first time series data from the first source and based at least in part on a portion of the second time series data from the second source, wherein the similarity metric comprises a statistic, wherein the statistic comprises a box plot (1830, 1930) statistic or a histogram plot (1850, 1950) statistic; analyze (730, 740, 750) the similarity metric with respect to the drilling operation associated with the borehole, comprising matching at least a portion of the first time series data from the first source to at least a portion of the second time series data from the second source based at least in part on the similarity metric, to provide insight as to drilling performance; and control the drilling operation with respect to the borehole based at least in part on the analysis of the similarity metric. a processor; memory accessible by the processor; a network interface; and processor-executable instructions stored in the memory to instruct the system wherein the instructions comprise instructions to: receive first time series data, i.e. data with respect to time, from a first source associated with a drilling operation for a borehole; receive second time series data from a second source associated with the drilling operation for the borehole; compute a similarity metric based at least in part on a portion of the first time series data from the first source and based at least in part on a portion of the second time series data from the second source, wherein the similarity metric comprises a statistic, wherein the statistic comprises a box plot (1830, 1930) statistic or a histogram plot (1850, 1950) statistic; analyze (730, 740, 750) the similarity metric with respect to the drilling operation associated with the borehole, comprising matching at least a portion of the first time series data from the first source to at least a portion of the second time series data from the second source based at least in part on the similarity metric, to provide insight as to drilling performance; and control the drilling operation with respect to the borehole based at least in part on the analysis of the similarity metric. receive first time series data, i.e. data with respect to time, from a first source associated with a drilling operation for a borehole; receive second time series data from a second source associated with the drilling operation for the borehole; compute a similarity metric based at least in part on a portion of the first time series data from the first source and based at least in part on a portion of the second time series data from the second source, wherein the similarity metric comprises a statistic, wherein the statistic comprises a box plot (1830, 1930) statistic or a histogram plot (1850, 1950) statistic; analyze (730, 740, 750) the similarity metric with respect to the drilling operation associated with the borehole, comprising matching at least a portion of the first time series data from the first source to at least a portion of the second time series data from the second source based at least in part on the similarity metric, to provide insight as to drilling performance; and control the drilling operation with respect to the borehole based at least in part on the analysis of the similarity metric.
