Abstract:
A method for using geological data to predict one or more stratigraphic attributes at a location, the method comprising the steps of:obtaining real geological data from a location in a sedimentary basin;providing initial values to a stratigraphic forward model for parameters that are used by said stratigraphic forward model to output a predicted value for a stratigraphic attribute at said location at which said real geological data were obtained, wherein said forward model incorporates a conservation of mass constraint;using said stratigraphic forward model determine a predicted value for a stratigraphic attribute at said location at which real geological data were obtained based upon values of said parameters;determining a difference between said predicted value for said stratigraphic attribute and said real geological data at said location;modifying, if said difference does not satisfy a predetermined criteria, said values of said parameters to reduce said difference between said predicted value of said stratigraphic attribute and said real geological data;repeating said steps of using, determining and modifying until said difference satisfies said predetermined criteria; andidentifying, if said predetermined criteria is satisfied, said predicted value for said stratigraphic attribute as a best prediction for the actual value of the stratigraphic attributes over the space of the stratigraphic forward model.
