Title: Generation of Abnormal Pressures Through Organic Matter Transformations: ABSTRACT

Author(s): James A. Momper

Article Type: Meeting abstract

Abstract:

Adequately heated hydrogen-rich organic matter will generate fluids in sufficient quantity to considerably exceed the volume-reduction of remaining kerogen. Resulting volume increases cause high fluid pressures in laminae of sealed, confined argillaceous rocks where organic matter is concentrated, forming or re-opening partings and fractures for oil migration and expulsion.
