Duane-Dopkin_sm.jpgDear Fellow Geophysicists, 

Welcome to this year’s virtual SEG and a special welcome to the Emerson virtual booth. We have compiled over twenty presentations covering a wide variety of topics of interest for the SEG community. These topics are organized into your geophysical business challenges below.  To assist you in navigating through these challenges, we have provided several solution keywords that should help direct you to the presentation of your interest. All presentations are available on-demand. We hope you find this program relevant in extending the life of your field. 

As you will see from the program, Emerson continues to build upon its 30+ years of developing and delivering exceptional, production-ready solutions that can be applied to your seismic assets through flexible software licenses and services. 

We look forward to your participation in our program and the SEG.

Sincerely yours, 
Duane Dopkin    
EVP Geosciences, Emerson


Geophysics and the Digital Transformation

Thm_Geophysics-and-Digital-Transformation.pngGeophysics is playing a significant role in the digital transformation, as new AI and Machine Learning methods are being  deployed and accepted, and high-performance cloud computing is elevating the delivery of geophysical services to oil and gas companies. Additionally, technology collaborations are becoming necessary to keep pace with this transformation. This session will include presentations that highlight the value and directions of the geophysical digital transformation.

Improvements in Seismic Imaging and Shallow Velocity Determination

Full flexibility in seismic imaging and inversion procedures is necessary to resolve low energy seismic events. The key to resolving these events is performing a proper full-azimuth decomposition of the fully recorded wavefield. Full-azimuth diffractivity and reflectivity gathers become a pathway for generating alternative images (diffraction and specular) to emphasize discontinuous and continuous events. 

Complexities in the overburden require the best from our imaging and velocity model building solutions to resolve deeper reservoirs. The shallow velocity model can be particularly challenging, due to variations in topography, lithology heterogeneity, thickness variations, channels, sills, erosional surfaces, salts, anhydrites, etc. These conditions can, in turn, create interpretation delays with the seismic method and lost time in keeping the drill bit in formation. This session includes presentations to help resolve near surface velocity problems using refraction tomography, joint refraction and reflection tomography, and full-azimuth tomography. 

Solutions covered in this session: Full-azimuth Imaging in the Local Angle Domain; Diffraction and Specular Imaging, Orthorhombic Imaging, Holographic Imaging, RTM and FWI; Refraction Grid Tomography, Joint Reflection-Refraction Tomography, Full-azimuth Reflection Tomography

The presentations will be available for viewing on October 12th.

  4. Workflow Considerations for Orthorhombic Velocity Modeling, Imaging and Fracture Characterization In the Depth Migrated Domain
  5. Resolve Near Surface Challenges Using a Joint Refraction-Reflection Solution
  6. Joint presentation by NVIDIA and Emerson - Accelerating Emerson E&P HPC Seismic Operations with NVIDIA GPU Technology

Cost Reduction and Time-to-result Improvements with Automation and Geoscience Workflows 

Thm_Cost-Reduction-and-Time-to-Result.pngThe seismic acquisition-to-prospect generation time cycle is typically 2-5 years. While there is a limit to how much time this window can be compressed without compromising quality, business collaboration, workflow automation, and algorithm and computational advances can greatly improve the time-to-result. This session includes presentations that focus on project time improvements obtained with advanced automated workflow procedures, which simultaneously reduce project costs. 

Solutions covered in this session: Workflow Automation, Advanced Interpretation and Modeling Workflows, Prospecting, Synchronized Velocity Modeling with Geologic Modeling

The presentations will be available for viewing on October 12th. 


Advances in Seismic Resolution

Thm_Advances-in-Seismic-Resolution.pngWhile high-resolution seismic acquisitions of the past 10 years have tremendously improved the seismic method, a significant number of reservoirs are still too thin to be resolved fully with the seismic method or have not been exposed to new broadband processing procedures. The presentations in this session address vertical resolution, spatial resolution, and azimuthal resolution problems, and deliver innovative seismic inversion and imaging solutions to improve them.

Solutions covered in this session: Quantitative Seismic Interpretation; Modified Stochastic Inversion, Natural Fracture Determination; Stratigraphic Interpretation

The presentations will be available for viewing on October 12th. 

  1. Improving Resolution of Seismic Rock Property Estimation
  2. Stratigraphic Interpretation of 3D Seismic Data – Workflows and Patterns
  3. Seismic Analysis of Well Data - Minimizing Uncertainties in Seismic Interpretation and Seismic Reservoir Characterization

Measuring and Optimizing Geophysical Uncertainty 

Thm_Measuring-and-Optimizing.pngSeismic acquisition is never ideal due to limitations in spatial sampling, temporal sampling, sampling density and sampling area. Achieving an ideal acquisition is cost-prohibitive, while limited seismic acquisitions result in datasets where multiple models fit the data. Asset teams would like the sources of uncertainty, particularly velocity uncertainty, to be captured and incorporated in the E&P value chain, from seismic imaging to interpretation and modeling, to reservoir simulation. This session is dedicated to methods that integrate the geophysical and geological data and model to reduce geophysical uncertainty. 

Solutions covered in this session: Velocity Model Uncertainty, Well Marker Mistie Tomography, Traveltime Preserving Tomography

The presentations will be available for viewing on October 12th. 

  1. Precision Depthing for Shale Players Improves Well Placement and Steering 
  2. Model-based Tomography for Accessing Subsurface Structural Uncertainty
  3. De-risk Your Reservoir Architecture: Model-Driven Interpretation and Structural Uncertainties
  4. Quantify Seismic Uncertainties on GRV Calculations Based on Velocity Models and Seismic Resolution Constraints
