A sample from this course
One topic, as StudyPath teaches it.
Origin and composition of petroleum and gas
Petroleum and natural gas are the products of long‑term diagenesis of organic matter buried under sedimentary layers. Their composition—primarily hydrocarbons of varying chain lengths and heteroatom content—depends on the type of source rock, burial history and thermal maturity.
