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 . Petroleum geochemistry is used as the fundamental science for understanding the properties of source rocks, productive and non productive zones, oil migration (all of which result in more efficient exploration), development of oil fields and sustainable production. The term source rock refers to an organic-rich fine-grained sedimentary rock which can produce hydrocarbons due to thermal maturation . Source rock is one of the main elements of a hydrocarbon system. Rock Eval analysis using hydrogen index (HI) and oxygen index (OI) Obviously, the two main elements of hydrocarbons are hydrogen and carbon. Therefore, once we know the amount of total organic carbon (TOC) present in a rock, we then need to know the amount of hydrogen present in order to assess overall source rock quality. Petroleum source rock is defined as the fine-grained sediment with sufficient amount of organic matter, which can generate and release enough hydrocarbons to form a commercial accumulation of oil or gas [1]. Source rocks are commonly shales and lime mudstones, which contain significant amount of organic matter [2]. 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. petroleum-generating capacity of the source rock. Petroleum geochemistry is improving the effi-ciency of exploration and production through characterization of the elements and processes that control the richness and distribution of petroleum source rocks, thus providing valuable input for basin and petroleum system modeling. The type and maturity of organic matter in petroleum source rocks have been characterized from rock-eval pyrolysis data (Fig. 6). Geochemical parameters including HI [hydrogen index, ( S 2 /TOC) × 100], OI [oxygen index, ( S 3 /TOC) × 100] and PI [production index, S 1 /( S 1 + S 2 )] are calculated.

Areas with the highest charge are most likely to be nearest the source rock where it is the most thermally mature, or nearest the pod of active source rock. Conversely, areas most likely to have the lowest charge are farthest from the mature source rock, or farthest from the pod of active source rock.

The broadest element in source rock evaluation is the total organic carbon, or TOC, of a rock. TOC is the weigh percent of organic carbon present in a rock which is measured by the amount of CO2 released through combustion. The type and maturity of organic matter in petroleum source rocks can be characterized from Rock Eval pyrolysis data (see Fig. F5; from Emeis and Kvenvolden, 1986. This figure has been adapted for marine sediments cored by ODP.) using the following parameters: HI = hydrogen index (HI = [100 x S 2]/TOC). HI is a parameter used to characterize the origin of organic matter.
