G&G Training – Theory & Practical



Upon completion of this course, participants will gain an understanding of the concepts of formation evaluation and well logging, advanced seismic processing flow with an understanding of the physical principles of the tools used in open hole wireline logging; be able to read and interpret well logs; be able to characterize formations based on interpretation of well logs; an understanding of the various corrections applied to the logging tools; ability to discern porosity, water saturation, lithology, and hydrocarbon content from well logs; an understanding of the properties of rocks and fluids that produce characteristic signals.
