Abstract
Abstract Hydrocarbons are produced from source rocks in fluid communication with geopressured sections by (a) producing fluids from the geopressured section to reduce pressure, (b) shutting in to allow migration from the source rock to the formerly geopressured section, and (c) producing the migrated hydrocarbons from the section.
