Ensembles of tree-based machine learning models for electrofacies classification using well log data: a case study from an Iranian oil field

Journal of Petroleum Exploration and Production Technology
Electrofacies classification is essential for reservoir characterization, as it links well-log responses to lithological and petrophysical properties. A data-driven workflow was developed for electrofacies classification using routine well logs from an ...

Electrofacies classification of a mixed carbonate-siliciclastic reservoir using machine learning techniques [PDF]

Jurnal Natural
Many scientific fields, including the geosciences, have successfully employed machine learning to address numerous significant issues. Current studies show that the application of machine learning within the geosciences is still in its early stages, and ...

Fill‐and‐Spill, Tilt‐and‐Repeat (FaSTaR) cycles: Stratigraphic evolution above a dynamic submarine stepped slope

Basin Research, Volume 34, Issue 6, Page 2162-2188, December 2022., 2022
Amplitude map from the Oligocene–Miocene Marlim unit, which records the stratigraphic evolution of a turbidite system on a dynamic stepped submarine slope with multiple entry and exit points and fill‐and‐spill cycles. Abstract The classic fill‐and‐spill model is widely applied to interpret topographic controls on depositional architecture and facies ...

Stratigraphic evolution and carbonate factory implications: Case study of the Albian carbonates of the Campos Basin, Brazil

The Depositional Record, Volume 7, Issue 2, Page 271-293, June 2021., 2021
The main goal of the present study was to analyze the Albian carbonates of the passive margin of South America through the standpoint of sequence stratigraphy and carbonate factories. For this purpose, well data, 2D and 3D seismic data were employed. As a result, the succession was subdivided into five third order sequences that register the evolution ...

Detrital input quantification in lacustrine petroleum systems: An example of the pre‐salt source rocks from the Lower Congo Basin (Congo)

The Depositional Record, Volume 7, Issue 1, Page 147-171, February 2021., 2021
The aim of this study was to propose an integrated workflow to quantify detrital input into autochthonous lacustrine deposits in terms of regional extent and total organic carbon (TOC) content. This workflow includes (a) organic geochemical data such as Rock Eval data together with quantitative palynofacies assessment and (b) palaeogeographical maps ...

Development and Validation of a Novel Interpretation Algorithm for Enhanced Resolution of Well Logging Signals

Journal of Sensors, Volume 2021, Issue 1, 2021., 2021
This work presents a novel algorithm that achieves enhanced resolution of well logging signals, e.g., from 1 ft of a pulsed neutron mineralogy tool to 0.04 ft of an imaging tool. The algorithm, denoted as “Digital Core,” combines mineralogical and sedimentological information to generate a high‐resolution record of the formation mineralogy which can be

Electro-facies classification based on core and well-log data

Journal of Petroleum Exploration and Production Technology, 2023
Facies studies represent a key element of reservoir characterization. In practice, this can be done by making use of core and petrophysical data. The high cost and difficulties of drilling and coring operations coupled with the time-intensive nature of ...
