I am a fifth-year Ph.D. candidate in Civil Engineering at Tongji University, China, advised by Prof.Fengshou Zhang. I am currently a research scholar in the Sibley School of Mechanical and Aerospace Engineering at Cornell University, working with Prof.Jian-Xun Wang. I have been actively collaborating with leading researchers, including Prof.Xianda Shen from Tongji University, and Prof.Bicheng Yan from King Abdullah University of Science and Technology (KAUST).

My research lies at the intersection of artificial intelligence and geoscience, advancing the energy transition to a sustainable, carbon-neutral future. I am interested in developing AI-enabled computational frameworks for subsurface energy systems, with applications to geological carbon sequestration, shale gas exploitation, and beyond.

Generative Latent Diffusion Model for Inverse Modeling and Uncertainty Analysis in Geological Carbon Sequestration

Zhao Feng, Xin-Yang Liu, Meet Hemant Parikh, Junyi Guo, Pan Du, Bicheng Yan*, Jian-Xun Wang*

Code: GitHub

  • Our proposed CoNFiLD-geo combines conditional neural field encoding with Bayesian conditional latent-space diffusion, enabling zero-shot conditional generation of geomodels and reservoir responses across complex geometries and grid structures.
  • The model is pretrained unconditionally in a self-supervised manner, followed by a Bayesian posterior sampling process, allowing for data assimilation for unseen states without task-specific retraining.

SURGIN: SURrogate-guided Generative INversion for subsurface multiphase flow with quantified uncertainty

Zhao Feng, Bicheng Yan, Luanxiao Zhao, Xianda Shen, Renyu Zhao, Wenhao Wang, Fengshou Zhang*

Code: GitHub

  • SURGIN integrates a U-Net enhanced Fourier Neural Operator (U-FNO) surrogate with a score-based generative model (SGM), framing the conditional generation as a surrogate prediction-guidance process in a Bayesian perspective.
  • An unconditional SGM is first pretrained in a self-supervised manner to capture the geological prior, after which posterior sampling is performed by leveraging a differentiable U-FNO surrogate to enable efficient forward evaluations conditioned on unseen observations.

A hybrid CNN-transformer surrogate model for the multi-objective robust optimization of geological carbon sequestration

Zhao Feng, Bicheng Yan, Xianda Shen, Fengshou Zhang*, Zeeshan Tariq, Weiquan Ouyang, Zhilei Han

Code: GitHub

  • A hybrid CNN-Transformer surrogate model is developed to simulate time-varying CO2 injection into 3D heterogeneous geological fields.
  • Multi-objective robust optimization is implemented by integrating CNN-Transformer with Non-dominated Sorting-based genetic algorithm II.

An encoder-decoder ConvLSTM surrogate model for simulating geological CO2 sequestration with dynamic well controls

Zhao Feng, Zeeshan Tariq, Xianda Shen*, Bicheng Yan*, Xuhai Tang, Fengshou Zhang

Code: GitHub

  • An Encoder-Decoder Convolutional LSTM (ED-ConvLSTM) is developed for simulating CO2 flow under dynamic injection rates.
  • The proposed network has excellent capability in extrapolating to unseen time steps and to different geological settings.

A Data-Driven Model for the Prediction of Stimulated Reservoir Volume (SRV) Evolution During Hydraulic Fracturing

Zhao Feng, Fengshou Zhang, Xianda Shen, Bichen Yan, Zhaowei Chen

Code: GitHub | Slides: [slides]

  • A data-driven model is developed to use field monitored hydraulic fracturing parameters and microseismicity to predict the stimulated reservoir volume (SRV) ahead of time.
  • We use a voxelized method to calculate the SRV and a LSTM network to handle the time sequence regression task.
