Well Tie Methodology: A Very Often Overlooked Critical Step in Seismic Interpretation and Inversion

Joaquin Aristimuno and Carla Carvajal

In this article, we will explore the basics of the well tie to seismic, starting with some basic seismic acquisition and processing concepts, definition and type of wavelets and a case study that will show the impact of using a wrong estimation of the time-depth relationship (obtained from the well…
