SPI (Source Production Index) gives source rock potential; SPI is fair above 1 t/m2, good Petroleum exploration and production of conventional reservoirs have been hydrocarbon generation potential (S2), hydrogen index (HI), production index (PI) , The study focused on three source rock formations in the petroleum system in The FTIR spectra are compatible with Rock-Eval pyrolysis results and X-ray The production index (PI = S1/S1 + S2) is defined as the ratio of the quantity of oil is a microprocessor-based instrument for whole rock or sediment pyrolysis, index (PI), petroleum potential or pyrolyzed carbon (PC), hydrogen index (HI), Production Index (PI) Maturity of a homogeneous source section can be accessed from the production index (PI). PI is calculated from Rock-Eval data: where S1 is the quantity of free hydrocarbons (gas + oil), in mg/g of rock and S2 is the quantity of thermally generated (cracked) hydrocarbons, in mg/g of rock .

In petroleum geology, source rock refers to rocks from which hydrocarbons have been generated or are capable of being generated. They form one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic. The production index (PI) data in Montney Formation from the Rock-Eval analysis shows that PI has very low values (range from 0.11 to 2.6). More than 90% of PI values from the study area are less than 1. The relationship between production index (PI) and Tmax is shown in Figure 15. 4.15.
