Abstract

A method includes drilling a wellbore in a current well. An interval of the wellbore comprises a first portion of the wellbore and a second portion of the wellbore. The method also includes obtaining an offset drilling log and an offset lithology log for a geologically similar interval in an offset well and training a first machine learning model, using the offset drilling log, to produce a first trained machine learning model. The method further includes producing, using the first trained machine learning model, a forecasted drilling log for the second portion of the wellbore in the current well, training a second machine learning model, using a gradient boosting machine learning technique, the forecasted drilling log, and the offset lithology log, to produce a second trained machine learning model, and producing, using the second trained machine learning model, a forecasted lithology log for the second portion of the current well.
