Hei!

I am working as a Senior Data Scientist at PRORES AS for projects related to oil and gas exploration & production. In PRORES AS, I am the developer of Rock Insight (automated porosity and permeability prediction from core photographs) and Cuttings AI (automated lithology interpretation of cutting images).

Previously, I worked with Asia Pulp and Paper Sinarmas as Expert Data Scientist for projects related to pulp and paper manufacturing and precision forestry. I was also Chief of AI at Agrari, Indonesian agribusiness startup. My expertise are in Advanced image processing and analysis, Computer vision (YOLOv8/v11, Detectron) for aerial image & LiDAR, Large Language Models (LLMs), tech stacks (Linux, SQL, AWS, Spark Databricks).

Current Projects

Here are top 3 list of recent POCs I ran independently of PRORES AS:

  1. CavingDetection
Caving.Computer.Vision.mp4
  1. PetroRAG

Repositories

Since 2020, I have 130+ repositories. Mostly to liberate Machine Learning knowledge for subsurface. Here are top 5 most popular repositories:

  • PyReservoir - Python utilities for reservoir engineering calculations. PVT analysis, Well Test, Volumetric Mapping, Material Balance, and Decline Curve Analysis.
  • Formation Evaluation - Python utilities for formation evaluation and petrophysical analysis
  • Volve Machine Learning - Machine learning implementations on Equinor's Volve oil field and other open-source datasets, with articles in Towards Data Science.
  • DASLab - Distributed acoustic sensing lab of modules and functions developed for fiber-optic research (developed at RITE)
  • Computational Geophysics - Computational geophysics with Python

💻 Educational Resources

Want to start Python? 🐍 I have taught to more than 1,000 students and professionals through many courses with Society of Petroleum Engineers (SPE) and Marietta College in Ohio, US. Please start from this repository.

Python Bootcamp for Geoengineers - All YouTube video links, notebooks, data, and exercises from courses that I have taught with SPE and many more.

Want to solve reservoir engineering cases with Python? I also have tutorial articles in LinkedIn:
