This paper discusses our proposed methodology that we (Dr. Kazuo Nakayama in FGI Tokyo and my colleague Kevyn Augusta) developed to evaluate the capacity of seal rock for CCS using the Equivalent Grain Size (EGS) method. Using relation between seal porosity and pore throat size, the EGS method assumes hydrodynamic equilibrium of CO2-gas mixed fluids to calculate each column height in the carbonate reef structure and maximum pressure allowed for CO2 injection.

This was presented in a series of webinar organized by SPE Asia Pacific University and SPE Northern Emirates virtually in Malaysia. In this webinar, I presented a motivation presentation for students and young professionals on the education of programming for petroleum engineering and geoscience domains. I showcased some of my open-source works written in Python.

This was presented in a community sharing event organized by NEUSTRA Community (community of petroleum engineering ML enthusiasts) and SPE Alexandria University Student Chapter. On this occasion, I presented my project on sonic log synthesis / missing sonic log prediction using Gradient Boosting model.

This was presented in the SAGE/GAGE Workshop on Distributed Acoustic Sensing organized by IRIS held virtually in October 2021. In this presentation, I shared our research progress in RITE. Our research specifically focuses on the application of DAS fiber-optic cable for seismic activity monitoring in Japanese areas.

This was presented in King Fahd University of Petroleum and Minerals (KFUPM) virtually in Dhahran, Saudi Arabia. In this presentation, I discussed about the promising role of data analytics in the three phases of CCS projects, namely ANN in the site selection phase, data-driven surrogate modeling in the sequestration phase, and CNN in the monitoring phase.
