Claim 14:
15. A computer-implemented system, comprising:
one or more processors; and
a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
selecting, using statistical analysis from a set of independent variables corresponding to production features of an oil well in a reservoir, a subset of independent variables corresponding to production variables of the oil well, wherein the production variables include performance variables for production of the oil well, design variables of a design of the oil well, and modeled independent variables of the oil well;
training, using historical records of sidetracks from producer wells, a sidetrack performance prediction model configured to use the modeled independent variables to predict a performance of future sidetracks;
determining, using the subset of independent variables and machine learning, predicted values of dependent variables including an oil gain (ΔQo) and a water reduction (ΔQw) associated with production of the oil well;
predicting, as predicted oil gains by using the sidetrack performance prediction model, oil gains derived from horizontal sidetracking of producer wells using past production performance, subsurface information, and sidetrack design parameters;
generating, in a graphical user interface and based at least in part on the predicted values of dependent variables and predicted oil gains in a producer well in the reservoir that is re-purposed in the reservoir, a display specifying incremental values of average rate variations over a cumulative time window; and
re-purposing, based at least on the sidetrack design parameters, the producer well in the reservoir to access new sections of the reservoir to recover further hydrocarbons from the reservoir.
