Hydrocarbon expulsion, migration, and accumulation (view source)
Revision as of 00:00, 29 April 2014
, 00:00, 29 April 2014→Migration
Hydrocarbon generation causes pressure build-up in the [[source rock]], exceeding the pore pressure of the adjacent aquifer. Oil or gas is expelled or “squeezed” into the aquifer due to the differential pressures between source rock and aquifer fluid.
