WebAfter training different MLs on the designed lithofluid facies logs, we chose a bagged-tree algorithm to predict these logs for the target wells due to its superior performance. This algorithm predicted HC units in an accurate interval (above the HC-fluid contact depth), and it showed a very low false discovery rate. Web1 nov. 2024 · Abstract—An approach to parameterization of prior geological knowledge concerning the changes in depositional environment in space and geological time for their quantitative use in the workflow of seismic inversion is presented. The idea is to describe the observed or expected facies diversity in terms of a few statistically independent factors …
What I do first is calculate a lithofluid-class log (LFC) in which I separate groups of data identified by similar lithologic and/or pore-fluid content. The values of the LFC log will be assigned following these rules: First I need to create the “flag” logs brine_sand, oil_sand, gas_sand and shale (these are logs … Meer weergeven To handle well-log data, I use a Python library called Pandas, which makes it very easy to manage and inspect large, complex data … Meer weergeven In this tutorial, we have laid the foundations for the real work.
