Generating Watertight Isosurfaces from 3D Seismic Data [article]

Muhammad Sulaiman Khan, Hamish Carr, Doug Angus
2016 Computer Graphics and Visual Computing (CGVC)  
Isosurfaces and Fiber Surfaces are proposed for extracting horizons from seismic data.  ...  This research demonstrates extracting watertight geometric surfaces from 3D seismic volumes to improve horizon identification and extraction.  ...  For parallel and distributed computing, we are using VisIt [CBW * 12] on cluster to generate isosurfaces from seismic data.  ...

Application of a Vertical Electrical Resistivity Array (VERA) for monitoring CO2 migration at the Ketzin site: First performance evaluation

Cornelia Schmidt-Hattenberger, Peter Bergmann, Dana Kießling, Kay Krüger, Carsten Rücker, Hartmut Schütt, Ketzin Group
2011 Energy Procedia  
Further use of the time-lapse resistivity data is in progress, e. g. support of CO 2 distribution mapping in conjunction with results of seismic measurements.  ...  From the first results of the ongoing project we can conclude that crosshole ERT is indeed valuable as part of the CO 2 monitoring program.  ...  Fig. 10 10 3D inversion result of field data from June 2009 vs. baseline data, where isosurfaces with resistivity ratios U monitor /U base > 2 have been drawn.  ...

Numerical approach to synthesizing realistic asteroid surfaces from morphological parameters

X. Li, J.-B. Vincent, R. Weller, G. Zachmann
2021 Astronomy and Astrophysics  
The meshes created with our algorithm can be directly used with existing visualization software and operations or science pipelines to generate data suitable for mission planning and to validate data analysis  ...  In this paper, we propose a novel method to synthesize physically correct 3D shape models of small celestial bodies, such as asteroids, to support the testing of a wide range of parameters in scientific  ...  In order to generate a watertight mesh, we extracted the isovalue points from the 3D grid and used a screened Poisson surface reconstruction algorithm (Kazhdan & Hoppe 2013) to generate the final mesh  ...

Computational Fluid Dynamics with Embedded Cut Cells on Graphics Hardware

Alo Roosing, Apollo-University Of Cambridge Repository, Apollo-University Of Cambridge Repository, Nikos Nikiforakis
2019
We demonstrate efficient generation and handling of geometric surface data in rectilinear computational grids.  ...  Multidimensional simulations use a framework of data transposes to align data with sweep dimensions to maintain optimal memory access.  ...  The SDF generator code benefitted from enlightening discussions with Oliver Strickson who also helped provide a proof of completeness for the underlying algorithm.  ...

Numerical simulation of fracture pattern development and implications for fuid flow

Adriana Paluszny Rodriguez, Martin Blunt, Stephan Matthai, Janet Watson Scholarship
2010
Geomechanically generated fracture patterns are the input to single-phase flow simulations through fractures and matrix.  ...  We describe an iterative geomechanics-based finite-element model to simulate quasi-static crack propagation in a linear elastic matrix from an initial set of random flaws.  ...  The introduction of graphical tools suitable for the geologic interpretation of seismic data, maps, and cross-sections from mines has facilitated the generation of rigorous three-dimensional structural  ...
