Perform petrophysical log interpretation and formation evaluation for oil and gas wells. Covers shale volume from gamma ray using linear and Larionov methods, porosity from density log, sonic Wyllie time-average, and neutron-density crossplot, water saturation using Archie equation, Simandoux, and Indonesian equation for shaly sands, irreducible water saturation from Buckles number, moveable hydrocarbon index, net pay zone cutoffs, and brittleness index from compressional and shear slowness for completion quality assessment in unconventional reservoirs. Use when interpreting wireline logs, calculating formation properties, evaluating pay zones, estimating reservoir quality, or working through log analysis for PNGE courses. Trigger phrases include shale volume from GR, Archie water saturation, neutron density crossplot, sonic porosity, log interpretation, net pay cutoff, completion quality from logs, brittleness index, Sw calculation, Vshale, formation evaluation, petrophysical analysis, or Marcellus log interpretation.
