Advanced classification techniques
Automatic facies identification is playing a key role within the oil
and gas E&P industry. Ipsom is a unique classification method that
brings added value to interpretation workflows.
The 2D indexed and probabilised self-organizing map (Ipsom) is
designed for use in :
geological interpretation of well log data and facies
prediction
optimal derivation of petrophysical parameters (phi, k,
hydraulic units...)
Comprehensive statistical tools
During the final control and validation phase, results are quantified
and refined through an iterative process. High quality statistical and
graphic tools with total interactivity and great ease of use, lead to
a better understanding of coherence between core description, log
responses and consistency on the map.
Accurate model calibration The key to the classification process is calibration. The aim of
calibration is to give each neural unit an actual geological meaning:
this is known as the indexation phase. Each neural unit is assigned a
code that corresponds to a geological interpretation (detailed core
description). This stage is essential for a direct interpretation of
electrofacies in sedimentological terms.
