GEOLOGY

Detailed explanation-1: -Source rock hydrogen index (HI) is a maturity proxy, and a hydrogen index can be used to map relative maturity. HOWEVER, that only works if the source rock being targeted has the same original HI vertically through the sedimentary column and has the same original HI laterally all across the basin …

Detailed explanation-2: -The maturity of a source rock reflects the ambient pressure and temperature as well as the duration of conditions favorable for hydrocarbon generation. Understanding maturation is especially important in shale reservoirs because of the shales dual role as source rock and reservoir rock.

Detailed explanation-3: -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].

Detailed explanation-4: -Quantity of organic matter. Quality capable of yielding moveable hydrocarbons. Thermal maturity. 04-Feb-2022
