To heat shale material on certain temperature can alter its organic compound and change it physically and chamically which then can produce energy resources such as oil and gas. Researcher has sucessfully conducted a synthesis on shale material using illite and calcite as the basis. The outcome shows that those materials are acted suitably as oil shale. SEM and XRD analysis outcome show that both shale materials have small pores because the pores cavity evenly filled by organic material, accumulated and bound strongly with illite, kaolinite or calcite, and other materials in small percentage. Moreover, the temperature to change shale material into crude oil (Tmax) on both materials is well-suited to oil shale, i.e. 421OC-453OC. Tmax of carbonate- organic (400OC-450OC) is higher than clay-organic (325OC-430OC). The formation of gas on carbonate-organic (T�over=750OC-1000OC) is higher than clay-organic (T-over=650OC�900OC). The outcome of TGA and Pyrolysis analysis also show similarity, i.e., all three materials have maximum maturation level on 322 OC, 323OC, and 493 OC, indicating different thermal maturation level in which carbonate shale needs higher temperature and longer time than clay shale. Outcome of pyrolysis suggests clay-organic hydrocarbon has a better potential (PY=605,06-652,45 mg/g and TOC=19,94-34,38%) than carbonate-organic (PY=164,53 mg/g and TOC=9,14%). Combination between Hydrogen Index (HI) and Tmax shows clay-organic taking role as oil shale that more likely potential to be oil and gas, while carbonate-organic is not a perfect oil shale yet.
