Lost Hills Contractional Growth Structure
DiscussionIn this example StructureSolver is used to model a contractional growth structure, approximately duplicating the model produced by Don Medwedeff for the Lost Hills Anticline.
A near vertical shear angle is used to approximate flexural slip folding. Nevertheless the main features of Medwedeff's model are rapidly reproduced. A good estimate of the deeper fault ramp is also obtained.
In a similar way StructureSolver can be used to model the deepwater contractional growth structures that are found offshore the Gulf Coast and offshore parts of West Africa.
