<p align="justify">Characterization of shale stone is a necessity in the exploration and exploitation of a kind of unconventional reservoir, it is oil and shale gas. It’s purpose is determining prospective zone. Physical properties of shale rock to be characterized are clay, porosity, brittleness, organic matter and pore in kerogen. One of the easiest ways to characterize is Rock Physics Template (RPT). Because the rock could be characterized only by plotting the data on its elastic graph parameters. However, recent research is simply, because it makes RPTs that can characterize 3 physical properties there are clay content, porosity and brittleness. At present, RPT is designed to characterize 5 physical properties of shale include organic matter and pore in kerogen. The method of making RPT is by forward modeling of shale rock. The model is a Sun (2014) modified model. Forward modeling's purpose is to detect contribution of kerogen and pore in kerogen on elastic parameters. A sensitivity test was then performed to determine the most sensitive elastic parameters for kerogen and pores in the kerogen. The elastic parameter will be used as RPT. The RPT, which has been calibrated by the CR well data of South Sumatera Basin, is able to characterize 4 physical properties of shale, then RPT are engineered to differentiate between porosity effect and kerogen effect by deleting kerogen effect. The Result show RPT that characterize 4 physical properties better.<p align="justify">
