Data Hierarchy – The Correct Basis for Petrophysical Data Integration
The ever increasing diversity and abundance of petrophysical data presents choices as to how to best use numerical data and qualitative information in a quantitative petrophysical workflow. The decision as to which data to use, where and how is usually a subjective process left to the expert. He/she rarely discusses options with other disciplines and often remains unaware of possibilities. This process of which data to use, where and how should be further examined and formalised with guidelines as to why data is or is not useful. This thinking does not yet seem to have evolved in companies but is the necessary first step to robust integration. Much useful data is ignored by petrophysicists. We must remain eternally vigilant as to the relevance and possible function of new data items in our existing workflows. Workflows must evolve with new data, that is our task, to use everything at our disposal in the most efficient manner. Most established wo...
