Abstract: The invention relates generally to the field of oil and gas exploration and specifically to the use of well logs for exploration. This invention is directed to a method for estimating data that would have been collected in a region of a well log where there is a gap. This method uses identified elements in one data set to identify elements in another data set with data values indicative of the same geological characteristic as those in the first data set.

Abstract: A method for includes obtaining a well log comprising a sequence of measurements of a wellbore in a field, and generating change points in the well log based on the sequence of measurements. Each of the change points corresponds to a depth along the wellbore where a probability distribution of the well log changes. The method further includes generating a statistic for each of multiple intervals in the well log, where the intervals are defined by the plurality of change points, categorizing the intervals based on the statistic for each of the intervals to generate categorized intervals, and performing the operation based on the categorized intervals.
