− | Hydrocarbon types reflect the composition of the [[kerogen]]s from which they were generated and provide an estimate of the potential number of source-rock intervals or variations of kerogen facies within a [[source rock]]. We can prepare or locate a map showing the distribution of hydrocarbon types. | + | Hydrocarbon types reflect the composition of the [[Kerogen types|kerogen]]s from which they were generated and provide an estimate of the potential number of source-rock intervals or variations of kerogen facies within a [[source rock]].
