Well Log Interpretation Principles and Applications Training

Introduction of well logging operations

Fundamentals of rock modeling and general parameters: porosity, resistivity permeability, temperature and pressure, along with water saturation calculations.

Understanding logs: Log presentations, scales, typical curves

Basic tools: spontaneous potential, gamma ray, natural gamma ray spectral logs, calipers and logging techniques for both wire-line and MWD/LWD operations.

Resistivity logs: laterolog, induction logs, micro resistivity devices, depth of investigation, tool responses, borehole corrections.

Porosity logs: Neutron and Density logs, principles of operation for log tools and techniques to drive porosities from neutron, and density logs, and discussion of “Borehole Effects”.

Acoustics: sonic logs, porosity derived from sonic logs, Wyllie time average equation, introduction to compressional and shear wave logging, basic rock mechanics principles.

Interpretation principles, Archie equation, cross plots Density Neutron, M-N, picket plots, Rw (water resistivity) and salinity determination, and lithology identification.

Log quality control

Geological logs: Old dipmeter log and formation imager logs. Basic geological interpretation.

Modern logging tools: Nuclear Magnetic Resonance & Dielectric tools.
