1. A method comprising:
accessing data associated with a well and one or more offset wells, wherein the data comprise data that correspond to multiple instances of performance of a well-related activity that utilizes a rig;
based on at least a portion of the data, generating a set of distributions via parametric estimation that determines parameters for each distribution in the set of distributions, wherein the distributions are for the well-related activity and correspond to time to perform the well-related activity;
via hypothesis testing, automatically analyzing individual distributions in the set of distributions with respect to at least a portion of the data to pass or fail each of the individual distributions;
for one or more passed individual distributions, outputting one of the passed individual distributions for the well for estimating a time to perform the well-related activity at the well; and
generating one or more graphical user interfaces that indicate the well-related activity for the well, the one of the passed individual distributions for the well and an estimated time for performance of the well-related activity based on the one of the passed individual distributions, and wherein the one or more graphical user interfaces indicate offset well information utilized to generate the one of the passed individual distributions.
