Claim 0:
1. A method of moving a plurality of rigs, the method comprising:
receiving, by one or more processors, a plurality of wells, each well of the plurality of wells defined by a plurality of well attributes;
receiving, by the one or more processors, a plurality of historic wells, each historic well of the plurality of historic wells defined by a plurality of historic well attributes;
comparing, by the one or more processors, the plurality of well attributes with the plurality of historic well attributes;
selecting, for each well of the plurality of wells, one or more matched historic wells based at least in part on a similarity between the plurality of well attributes for an individual well of the plurality of wells with the plurality of historic well attributes of the one or more historic wells; and
calculating, for each well of the plurality of wells, one or more well parameters based at least in part on the one or more matched historic wells;
generating a Markov Chain model from the historic well data and the historic rig data, wherein:
the Markov Chain model comprises a plurality of states and a plurality of links between states;
each state of the plurality of states is a well class derived from the historic well data; and
each link indicates a number of rigs that traveled between individual well classes;

determining, using the Markov Chain model, a probability of rigs moving between individual well classes; and
predicting movement of individual rigs of the plurality of rigs between the plurality of wells based at least in part on the Markov Chain model;
generating a drilling schedule for the plurality of rigs based at least in part on the predicted movement of the individual rigs and the one or more well parameters of each well of the plurality of wells; and
moving the plurality of rigs to the plurality of wells in one or more fields according to the drilling schedule.
