Basic Geophysical Petroleum Exploration: A High Velocity Anomaly Case

In the Hydrocarbon Industry seismic and petrophysical methods play a fundamental role in the exploration stage such in the acquisition stage as well as their subsequent processing of the seismic data and finally the interpretation of the data which the first descriptions of the basin both structurally and stratigraphically are gotten. For that reason having mistakes in one of those steps can finish in large sum of money lost. Due to the mentioned before this book tries to show some basic concepts about Geophysical Petroleum Exploration covering topics about Petroleum Geology Petrophysics Seismic Acquisition Processing and Interpretation exemplifying them using a case of study. This case of study corresponds to a zone with an imperceptible high velocity anomaly because of it it was necessary defining the geology as well as a seismic and petrophysical interpretation. After this it was used synthetic models obtaining a geological section designing a 2D line applying ray-tracing getting synthetic gathers which were processed applying a pre-stack migration either in time and depth solving finally the problem caused by the imperceptible anomaly.
