For many years, geoscience students have struggled in getting industry-based and hands-on processes or data used in hydrocarbon reserve estimation using a variety of data. Most times the lack of data or incomplete data and lack of access to geoscience software for analysis and interpretation have always stood in the way for students. Very few academic literature that explains the techniques used in interpreting seismic data, surface map generation, seismic stratigraphic interpretation, hydrocarbon estimation and prospects analysis exist. This book provides the simplified technique necessary for going through data loading, seismic (fault and horizon) interpretation, synthetic seismograph and surface mapping generation, well logs interpretation, determining hydrocarbon zones, hydrocarbon reserve estimation and calculating the prospects of your findings according to fair market price for oil and gas reserves in the field. Following the steps used in the case study project in this book and the help manual in a simple Petrel demo software, you can learn and use almost all the geology and geophysics tools to have this very important knowledge and tool for your Geoscience career.
