The application of Paradise® Machine Learning technology to predict
lithofacies distribution within a producing oil field in the Oriente Basin, Ecuador
Overview
This presentation demonstrates the application of Paradise® Machine Learning technology to predict lithofacies distribution within a producing oil field in the Oriente Basin, Ecuador. The results were obtained more quickly and provided greater detail than traditional seismic inversion techniques.
The study addressed a particularly challenging geological setting in which target sand bodies occur at depths of approximately 8,900 ft and range in thickness from only 8 to 18 ft (3–6 m)—well below the conventional seismic resolution limit of approximately one-half wavelength (~40 m). As expected, conventional seismic inversion methods were unable to reliably identify or characterize these reservoirs.
The machine learning workflow integrated approximately 100 km² of migrated full-stack and partial-angle-stack seismic data with open-hole log data from 13 wells. Lithofacies were first classified using K-means clustering applied to petrophysical logs. Self-Organizing Maps (SOMs) were then generated to establish multidimensional clustering using seismic attributes. Relationships between SOM clusters, or neurons, and lithofacies were identified through detailed time-to-depth calibration. Statistical quality-control metrics were used throughout the workflow to evaluate prediction uncertainty and reliability.
The reservoirs were deposited in a coastal-to-continental transitional environment characterized by highly heterogeneous lithofacies distribution and predominantly stratigraphic trapping, making seismic characterization particularly difficult.
Results demonstrate that the machine learning workflow successfully delineated the distribution of thin reservoir sands despite their sub-resolution thickness. The predicted lithofacies also showed a strong correlation with reservoir fluid content, providing a level of discrimination beyond the original project objectives.
The presentation will discuss the workflow, validation methodology, uncertainty assessment, and the implications of applying machine learning to reservoir characterization in geological settings where conventional seismic techniques reach their practical limits.
What You’ll Learn
- How petrophysical log classification, seismic-attribute analysis, machine learning, and statistical quality control can be combined to predict lithofacies at resolutions below conventional seismic.
- How statistical metrics such as Cramér’s V, Global Fit, and uncertainty analysis were used to assess the reliability of the predictions.
Why It Matters
Thin, heterogeneous reservoirs are often difficult or impossible to characterize using conventional seismic inversion alone. This case study shows how machine learning can extract useful geological and fluid-related information from seismic data where traditional methods provide limited results, helping interpreters improve reservoir delineation, reduce uncertainty, and support development decisions.
