Petroleum System – Source Rock and Migration
19th February 2010
by : Stephen Scott
Recently we invited Mr. Stephen Scott to give a lecture about Petroleum System especially about Source rock and Migration at UI Student Chapter, on 19th February 2010. This lecture was held to give the students explanation about generation and migration of hydrocarbons which is an important concept in HC exploration, and was attended by 24 students from University of Indonesia.
Mr. Scott started his explanation about source rock. He displayed in a chart that shows geologic time along the horizontal axis and the petroleum system elements along the vertical axis (event chart). And then, he explained about composition and maturation of organic matter, kerogen, anoxic condition, and source rock parameter. He explained them one by one in such an interesting way.
He also explained difference to determine oil and gas potential of source rock. After that he explained about organic facies. He displayed Van Krevelen type diagram for organic facies A through D. And then,he explained types reservoir fluids and their relationship to source rock.
After Mr. Scott finished his explanation about source rock, he explained about migration. In this section, he explained about migration drainage style and entrapment style. After that, he gave us a seismic interpretation exercise to identify potential source rock.
He also displayed a thesis about Migration Out Of A Rift Basin Half-Graben Along Two Structural/Stratigraphic Pathways. The thesis is written by Mr. Scott’s student. The thesis also explained axially drained rift model, general petroleum basin outline, axial oriented continuous carrier bed pathway, basin transmisivity method, petroleum migration “Shunting” model.
At last, Mr. Scott summarized his explanation. He had given us some knowledge about Petroleum System especially about Source Rock and Migration very well.
