System and method for well data analysis

摘要

A method of processing data generated from an energy industry or oilfield operation includes: receiving a data set representing parameter values generated during at least a portion of the operation, the parameter values including values of a plurality of parameters relating to the operation; dividing the data set into a plurality of data subsets, each data subset including values for multiple parameters; determining a measure of similarity between data in each subset relative to data in one or more other subsets; displaying a map of the data set in at least two dimensions, the map including a visual representation of each subset positioned relative to a visual representation of the one or more other subsets based on the measure of similarity; and analyzing the map to estimate a condition associated with the operation.

1. A method of performing a drilling operation, comprising:
receiving, by a processor, a data set representing parameter values generated during at least a portion of the operation, the parameter values including values of a plurality of parameters relating to the operation; and performing aspects of a drilling operation by the processor, wherein performing includes: dividing the data set into a plurality of data subsets, each data subset including values for multiple parameters; determining a measure of similarity between data in each subset relative to data in one or more other subsets; displaying a map of the data set in at least two dimensions, the map including a visual representation of each subset positioned relative to a visual representation of the one or more other subsets based on the measure of similarity, each visual representation having a position relative to one or more other visual representations and a proximity to the one or more other visual representations based on the measure of similarity; analyzing the map to estimate a condition associated with the operation, wherein analyzing includes identifying a group of visual representations representing subsets having at least one similar parameter, and estimating the condition based on a shape or structure formed by the group of visual representations; and adjusting a parameter of the drilling operation based on analyzing the map.
