Phasees Net Paper: A New Architecture for Rock Facies Classification
The podcast episode discusses the Phasees Net Paper, which proposes a new architecture for rock facies classification. The architecture combines sequence models and recurrent neural networks to accurately classify different types of rock facies. By converting well-logged data into spectrograms and using them as inputs, the model can generate high-resolution images that reveal the sequencing and texture of different facies. This approach improves upon previous methods that overlook the sequence aspect of facies classification. The paper achieves a significant improvement in accuracy, correctly classifying more types of facies compared to previous state-of-the-art techniques.
Least Squares Paper: Equivalent Workflow Processes for Full-Wave Inversion
The podcast also mentions a paper on least squares for seismic interpretation. This internal R&D approach developed by Shell utilizes machine learning and deep learning to create an equivalent workflow process for full-wave inversion. By leveraging deep learning frameworks and sequence models, the paper demonstrates a time-saving computational simplification compared to conventional physics-based approaches. This breakthrough enables the accurate identification of different types of zonal interest areas using seismic data, which historically required significant computational power and effort.
The Significance of Phase Inversion in Seismic Image Reconstruction
Phase inversion is explained as the process of reconstructing high-resolution images of prospects for finding hydrocarbon deposits based on seismic data from surveys. Traditionally, this has been a computationally intensive task that required months of effort and massive amounts of computing power. The podcast highlights how the Phasees Net Paper addresses these challenges by efficiently reconstructing seismic images using a deep learning framework. By accurately predicting facies types within these images, the paper offers improved capabilities for identifying areas of interest and reducing the cycle time for hydrocarbon discovery.
Platform Development and Collaboration Initiatives
The podcast also touches on Shell's efforts in platform development and collaboration. Shell is building an expandable open architecture platform based on Kubernetes, enabling the deployment and scaling of machine learning models for various applications. The platform aims to provide accessibility and support for real-time insights and decision-making. Additionally, Shell.AI Residency Program is introduced as a two-year program that invites PhDs, postdocs, and experienced individuals to collaborate on solving challenging machine learning problems in the energy industry. The goal is to shape the future of machine learning and foster innovation through collaborations between industry and academia.
Today we close out our 2019 NeurIPS series with Mohamed Sidahmed, Machine Learning and Artificial Intelligence R&D Manager at Shell. In our conversation, we discuss two papers Mohamed and his team submitted to the conference this year, Accelerating Least Squares Imaging Using Deep Learning Techniques, and FaciesNet: Machine Learning Applications for Facies Classification in Well Logs. The show notes for this episode can be found at twimlai.com/talk/333/, where you’ll find links to both of these papers!
