Back to fracturing history, the first commercial hydraulic fracturing may be done since 1949, but actually the idea of fracturing formation to quicken the production already exist since 1865. So the idea is more than a century old now. Hydraulic fracturing treatment design is one of an aspect that has been developed so much, until now people are able to generate a treatment design without consume much so time on that. Hydraulic fracturing treatment design has been vastly developed since 1953, until in the 2000s Gu, H. et al. has developed a method which includes numerical calculations and then automatically designs the hydraulic fracturing treatment to its most optimum option, and just needs to be told how far would the fracture go, and do it with what fluid and proppant. By the creator its named as Pump Schedule Generator (PSG). But far before that, in 1983 H. R. Crawford developed a methodology with a few calculations to calculate the volume of fracturing fluid needed based on the designed and desired fracture network dimensions, number of proppant needed, and also the production increase. This work analyses the comparison between the older method and PSG, and then modifies the schedule created by the older method to come up to the results of the PSG. A fracturing design simulator, FracCADE 5.1. was used in this study. It helps the writer to understand the basics of Pump Schedule Generator and the causes and effects of parameters to the EOJ result values. The formation’s structure and parameters were taken from an Indonesian shale gas reservoir.
