Well log formation evaluation

OSTI ID:6670622
A discussion of well logging tools, techniques, and well logging analysis principles is presented. Because no single well logging tool has been developed to measure all the physical properties of rock needed for detailed analysis, tool combinations that will measure porosity, water saturation, hydrocarbons in place, etc. have been developed for various geologic targets. Recently, computers have played an increasingly important role in aiding log analysts in developing systems which will analyze not only single wells, but also variations in geologic structures through a basin. Porosity is one of the most important rock properties to be determined in petroleum geology, and to determine it, three porosity tools and/or a resistivity tool are used. The porosity tools are typically sonic, density, and neutron porosity tools, and how the values from these logs can be converted into porosity units for the formation being examined is explained in some detail. In addition to porosity analysis, several quick look logging techniques are discussed along with total geologic analysis.
