The descriptive statistics of the data are shown in Fig. 7.1.Out of 29 wells, sand production was observed in 21 wells. Since data attributes have different ranges, it is recommended to scale the data between 0 and 1 for the learning process (data set can also be standardized; the proper data transformation can be determined by the performance of the model which will be explained in this chapter).

Benefits of Using Sand Casting. 1. Nearly any alloy: Sand castings can be readily produced in nearly any ferrous or non-ferrous alloy. Some other casting processes will melt and pour super-alloys in a vacuum, but that is not typically done as a sand casting. Some materials cannot be “worked”, and must be produced as a casting.
