Correlation-based imputation method for estimating missing well log data in a Hungarian groundwater well

Incomplete well logging datasets measured in boreholes are frequently encountered especially old wells. The main goal of the research, described this paper, is to refill a data matrix with synthetic that missing for some reason and how imputation procedure was determine estimated values fit case gaps different sizes, clay content porosity change as result. There can be many reasons lack data, such not measuring desired parameters given depth zone. To fill gap, correlation-based method used which applied MATLAB software development system. A study involving Hungarian thermal water shown demonstrate reliability multi-linear correlation based method, fruitfully other wells investigation areas.
