UPDATING MODELS OF COMPLEX GEOLOGICAL SEQUENCES

The present disclosure includes a method for updating models of complex geological sequences, which comprises: i) calculating a sediment accumulation rate volume by dividing a thickness between each system tract interval in a depth view of a three-dimensional systems tract interval model by a difference in time between each system tract interval in a time view of the three-dimensional systems tract interval model, wherein a thickness for each system tract interval vertically bound under each respective erosional unconformity is excluded from the calculation; ii) editing at least one erosional unconformity in an actual top-surface in one of the depth view and the time view; and iii) updating one of the Depth view and the time view using the sediment accumulation rate volume, the edited one of the depth view and the time view and a computer processor. Systems and methods for updating models of complex geological sequences using a sediment accumulation rate volume derived from a depth view and a time view of the complex geological sequences.
