Hackathon - AI for Oil & Gas

Dates: 10–14 November 2025 - In person at CBPF (Rio de Janeiro, Brazil)

Pitch and final jury: 18–20 November 2025 - during SBGF

About the event

The Hackathon is a marathon of applied innovation that challenges multidisciplinary teams to develop Artificial Intelligence for simulated and representative data of the Oil & Gas sector models.

Solutions must combine technical rigor, creativity, and industrial applicability, with final evaluation presented during SBGF 2025.

Objectives

  1. Develop innovative solutions for the analysis and interpretation of geophysical, petrographic, and NMR data with real-world application potential.
  2. Integrate academia, industry, and research centers, strengthening collaboration and knowledge transfer.
  3. Promote the strategic use of AI in complex sector problems, from exploration to reservoir characterization.
  4. Create a collaborative environment for networking and multidisciplinary partnerships.

Who can participate

  1. Researchers from universities, research centers, and companies.
  2. Professionals in data science, artificial intelligence, physics, geophysics, geology, engineering, and related fields.
  3. Undergraduate students in any area related to the event theme.
  4. Graduate students (master’s, PhD, or specialization).
  5. Other professionals interested in AI applications in the oil and gas sector, even without prior experience in the field.

Participation Requirements

  1. Have basic knowledge in programming and/or data science tools (Python, AI libraries, etc.).
  2. Have a personal notebook available for use during the event.
  3. Commitment to participating in person during all days of the hackathon (10–14/11/2025).
  4. Agree to the event regulations and the data usage rules.
  5. Be willing to work in a team and collaborate in a multidisciplinary environment.
  6. Limited spots: 25 participants.

Challenge Tracks

During the event, teams must choose two challenges organized into tracks:

  1. NMR: Estimate oil/water ratio in rock samples (NMR data).
  2. Petrographic Slides: Classify lithology in petrographic slide images.
  3. Seismic: Identification of seismic facies.

Track 1 - NMR (Nuclear Magnetic Resonance)

  1. Task: Regression (estimate of oil/water ratio).
  2. Input: Magnetic relaxation curves M(t).
  3. Output: Oil fraction - f(oil) and water (1−f(oil)).
  4. Data: Simulated curves with noise (different SNR - Signal-to-Noise Ratio ranges).
  5. Metrics: RMSE+R².

Track 2 - Petrographic Slides

  1. Task: Classification of petrographic images.
  2. Input: Synthetic petrographic images (256x256, RGB).
  3. Output: Example classes: spherulitite, stromatolite, laminite, reworked.
  4. Data: Synthetic set of images generated from models.
  5. Metrics: Accuracy (%) and macro F1-score

Track 3 - Seismic

  1. Task: Seismic facies segmentation.
  2. Input: Patches (224 × 224 in grayscale) generated from seismic images.
  3. Output: Pixel-by-pixel segmented masks with different seismic facies.
  4. Data: Seismic images generated from a public-domain seismic volume provided by New Zealand Petroleum and Minerals (NZPM), interpreted by Chevron and made available under the CC-BY-SA 4.0 license.
  5. Metric: Mean IoU (Intersection over Union).

Data Structure

  1. Each track will provide two data subsets: training and testing.
  2. The training set will contain the labels needed for solution development and tuning.
  3. The test set will be provided without labels and used exclusively for model evaluation during the hackathon.

(All datasets will be simulated and prepared for the event.)

Evaluation Jury

The jury will be composed of experts from CBPF, Petrobras, and strategic guests from academia and industry.

Project Evaluation

Solutions will be evaluated by the Evaluation Jury, considering the objective technical results presented, as well as the qualitative criteria established in this regulation.

Intermediate Publication (Technical Results by Track)

During the hackathon, each group will participate in two tracks. The results achieved in each track will be published on November 12 and 13 on the official event website, allowing everyone to follow the teams’ progress.

Objective: provide transparency, encourage joint learning, and enable groups to see how others are progressing.

Format: each group will have its results displayed within the technical metrics of the chosen track, without rankings.

  1. NMR: RMSE and R².
  2. Petrographic Slides: Confusion matrix, Accuracy, and F1-score.
  3. Seismic: IoU and related segmentation metrics.

This publication will be purely informative, serving for knowledge exchange and healthy comparison among groups working on the same track.

On the last day of the hackathon there will be no public disclosure of these results. They will be sent only to the evaluation jury as input for the final assessment.

Final Evaluation by the Jury

The final decision will rest exclusively with the Evaluation Jury, formed by experts from CBPF, Petrobras, and guests. Projects will be qualitatively analyzed according to the following criteria:

  1. Accuracy and Technical Performance - quality of results and model robustness.
  2. Generalization Capacity - potential of the model to extrapolate to new data.
  3. Approach Consistency - methodological coherence and technical justification.
  4. Innovation - originality of the solution and creativity in the use of AI.
  5. Applicability - relevance and practical feasibility in the oil and gas sector.
  6. Presentation Clarity - clear communication of methodology, results, and conclusions.
  7. Teamwork - collaboration, multidisciplinary integration, and division of tasks.
  8. Documentation and Reproducibility - quality of records and possibility of replication.

Results Disclosure

  1. The page with intermediate technical results will be available only during the hackathon, showing performance by track without overall classification.
  2. The official result will be defined by the jury after analyzing the solutions and will be published later on the event website.
  3. The jury may also grant honorable mentions (Innovation, Applicability, Reproducibility) and indicate projects for continuation in future initiatives.
