Previous HitVelocityNext Hit modeling with complex tectonics; example from the San Joaquin forearc basin, California


Lateral Previous HitvelocityNext Hit variations across steep thrust faults or steeply dipping beds are difficult to incorporate in Previous HitvelocityNext Hit models where structure is usually controlled by unfaulted, single-z grids. The west side of the San Joaquin basin is a tectonically complex environment with steep dips, unconformities, Previous HitvariableNext Hit fault geometries, complex basement lithologies, and outcrops to the west. All of these contribute to a complex structural model that is important to capture in Previous HitvelocityNext Hit modeling to allow for the most accurate depth conversion. In the past, geologic models had to be manually manipulated to account for discrete fault blocks. This process is time-consuming and difficult to update as interpretations change. Here we show how we are able to build a dynamic framework and resulting Previous HitvelocityTop model that accounts for fault offset, unconformities, and geologic history.
