The hydraulic fracturing analysis is conducted on T-2 interval of Telisa Formation, KB Field, Central Sumatra Basin. The stress regime and mechanical characteristic are analyzed using well logs data. Stress regime model from T-2 interval shows normal fault regime. The image log data display maximum horizontal stress direction from the northeast – southwest. The pseudo three dimensions (P3D) model is chosen to model fracture dimension and propagation. Hydraulic fractures tend to grow vertically as an implication of the normal fault regime. Mechanical character of T-2 interval is different from the adjacent interval. Hydraulic fracture of Telisa T-2 interval has a potential to break the adjacent interval because the thickness of T-2 interval is only about 20 ft. The thin formation will increase net pressure during hydraulic fracturing analysis. Stress regime controls the direction of fracture propagation. Mechanical properties affect fracture dimension significantly.
