Convolutional Neural Networks (CNNs) offer State-of-the-art performance not only for traditional computer vision applications but also for seismic interpretation. Geoscientists can use CNNs for basin-wide quick look interpretation of seismic data for fault, salt or facies identification. This helps in saving time on a lot of tedious work, thereby reducing the time to first oil. Machine Learning is a good tool for basin wide quick look interpretation, and prospect generation – which cannot be done with the classic tools available. When manually performed, only a very few interpretations are feasible.
A recent development in this field shows that CNN models that have been trained well on synthetic seismic datasets are producing acceptable accuracy in identifying faults using real datasets. Such solutions accelerate oil and gas exploration since geoscientists do not need to train models from scratch on newly acquired seismic datasets in order to get quick-look interpretation results – even at basin scale. Intel® Distribution of OpenVINO™ toolkit can help accelerate the inference pipeline for seismic interpretation, technical details on training and inference can be found in a recently published work. In that work, we showed a workflow (Figure 1) to use OpenVINO™ toolkit on a pre-trained model to perform inference faster without compromising accuracy on 2nd Generation Intel® Xeon® Scalable Processors (Cascade Lake) that can be availed in C5 instances on AWS. The Latest blog shows over 3x improvement with INT8 precision in fault detection seismic workload by leveraging OpenVINO™ toolkit and Intel® Deep Learning Boost (Intel® DL Boost). Intel® DL Boost includes new Vector Neural Network Instructions (VNNI) which enable INT8 deep learning inference (Refer to Optimization Notice for more information regarding performance and optimization choices in Intel software products).

OpenVINO AMI in AWS Marketplace
In order to facilitate accelerated seismic interpretation on AWS, Intel Energy and AWS Energy teams worked together to create OpenVINO™ AMI (Amazon Machine Image) based on Amazon Linux 2 operating system and published it in the AWS Marketplace (Figure 2).

Sample Jupyter notebooks are also provided to perform inference using OpenVINOTM toolkit from a pre-trained model. The AMI can be searched in step 4 of AWS Quick Start Guide with name OpenVINO. After you launch an instance from OpenVINOTM AMI, you can connect to it and use it just like you use any other server. For information about launching, connecting, and using instance, see Amazon EC2 instances. For more information on using this AMI, please visit AWS AMI instruction.

Following two sample Jupyter notebooks are provided as reference to use OpenVINOTM AMI on AWS.
- InceptionV3 for general computer vision-based applications
- Salt Identification in seismic data. This notebook uses a 3D CNN based model on data from the F3 Dutch block in the North Sea to identify salts. Salt-bodies are important subsurface structures with significant implications for hydrocarbon accumulation and sealing in petroleum reservoirs. On the other hand, if Salts are not recognized prior to drilling, they can lead to number of complications if encountered unexpectedly while drilling the well. The ability to quickly launch OpenVINO™ enabled instances in AWS to perform automatic quick look seismic interpretation from a pre-trained model will help geoscientists in reducing time to the first oil.
To access other pre-optimized deep learning models, visit OpenVINO™ – Open Model Zoo repository which provides free 100+ pre-trained models to speed-up the development and production deployment process.
