: Use interactive tools to "patch" bad data intervals or filter noise. 3. Core Interpretation Workflow
Dedicated tools for acoustic and electrical borehole image logs.
A standard interpretation in Interactive Petrophysics follows a sequential five-step workflow. Step 1: Quality Control and Data Conditioning
): Archie, Poupon-Leveaux (Indonesian), Simandoux, and Waxman-Smits models. 4. Advanced Interpretation Modules interactive petrophysics manual pdf
This is the heart of the deterministic workflow. The primary calculations are performed sequentially:
Geomechanics is crucial for well planning and drilling safety. The software can compute geomechanical properties using lithology-specific empirical correlations and models. A specialized module determines the likelihood of rock failure and sand production in sandstone reservoirs.
IP allows 10 different ways to compute shale volume. The manual gives the recommended workflows for clastic vs. carbonate environments, reducing decision fatigue. : Use interactive tools to "patch" bad data
: Export final results as new log curves or comprehensive PDF/Excel reports . Recommended Resources for Templates
The best way to get the most recent version of the manual is through the official Lloyd's Register (LR) portal or by contacting their support team.

Run depth-matching routines to align different logging runs. Apply environmental corrections for borehole size, mud weight, and salinity. Step 2: Lithology and Clay Volume ( Vclcap V sub c l end-sub ) Estimation
Align logs using a reference curve (usually the core data or a highly stable wireline Gamma Ray log).
Utilize dual-combination crossplots (Neutron-Density or Sonic-Density) to account for complex mineralogies or gas effects. Step 3: Porosity ( ) Calculation Calculate total porosity ( ϕtphi sub t ) and effective porosity ( ϕephi sub e ) from Sonic, Density, or Neutron logs. Correct porosity calculations using the Vclcap V sub c l end-sub output generated in the previous step. Step 4: Water Saturation ( Swcap S sub w ) Modeling
Modern versions of IP, such as and IP 2024 , include specialized modules to handle complex subsurface challenges: Interactive Petrophysics Basic User's Guide - Scribd
