Porosity, Gulf of Mexico
Porosity, Gulf of Mexico
Porosity predicted for the Gulf of Mexico (GoM) basin at at the beginning of the Lower Cretaceous time (100 Ma). This result is based on a regional fluid-flow modeling of the GoM evolution, which predicts the water pore pressure, porosity, temperature and maturation of organic matter (degree of conversion of organic matter to hydrocarbons) through time. The last 168 my of the GoM basin has was modeled by solving a set of deterministic differential equations that describe the fluid and heat transfer in evolving sedimentary basins. Porosity data from boreholes, pressure measurements and reflectance of vitrinite has been used to validate the model predictions for the present day time.

The rate of sedimentation in a geological sedimentary basin is an important information that gives clues of about availability of sediment in the vicinity areas as well as sediment transport mechanisms. Consequently, it helps to define the paleoclimate and paleogeography of the area. Rapid sedimentation when associated with low permeability sediments (shales) can also trigger the phenomena of excess pore pressure generation in sedimentary basins as it occurs in the Golf of Mexico basin.
