Abundant geological and geochemical data of Eocene source rock in Huilu area were analyzed and published for the first time.
A revised general hydrocarbon generation and expulsion conceptual model was established.
Hydrocarbon generation and expulsion characteristics of Eocene source rocks were quantitatively characterized.
Tight oil resource potentials in Eocene tight sand reservoirs were assessed.
The discovery of Eocene tight oil potential is opening up a new stratum for oil exploration in Pearl River Mouth Basin.
