PETROPHYSICAL GROUPS, PETROPHYSICAL LOGS AND PC ANALYSIS
In this tutorial, we introduce a non exhaustive list of the options available in Techcore module. The work flow that will be presented here is as follow:
- Create a new project and import all data needed (numeric and alpha numeric data, zonation, pictures, aso)
- Check the validity and coherency of the data
- Creation of petrophysical log by interval of representativity and by kriging

Using a Python script to create Well Properties Date:
In this tutorial it is assumed that the requisite Python script (wellPropertyZonePositions_v12.py) already exists; this tutorial does not cover the creation of a Python script.

K.mod© – modelling/repair of core and/or log data
The main objective when using K.mod© is to create a network model to predict the values of a desired formation property (e.g. permeability), or the values of a desired logging curve, from a combination of input log data. In the first case, the objective would be to predict the formation property outside cored intervals whilst in the second case the objective would be to create modeled curve...
IPSOM© – Characterization of Core/Log data Date:
The Self Organizing Map (SOM) is a tool for classifying multivariate data samples according to the “patterns” (or multivariate responses) to be found within the data. As such, the method proposes an “unsupervised” classification of a set of input data.

Saturation modelling involves creating relations (or tables) that express saturation as a function of Capillary Pressure or height, and possible other reservoir properties. This relation is then used to calculate saturations in Static and dynamic reservoir models. Creation of Saturation Models is an integral part of the Petrophysical workflow and an efficient workflow in Techlog is required to avoid time-consuming Excel solutions. This document...
