Three Dimensional Simulation Small-Scale Heterogeneity in Tidal Deposits Small-scale heterogeneity at the bed-set scale (ca 1 mm to 1 m) represents an important target for reservoir modelling. In particular, tidal deposits, which are typified by bi-directional currents and deposition of alternating mud and sand layers, have a high degree of...
Spectral Decomposition For a More Accurate Image, AAPG Explorer, May 2016, by Rongfeng Zhang
Spectral Decomposition For More Accurate Image When seismic data is decomposed into individual frequency components, as is done in spectral decomposition, some subsurface features, such as channels, can be distinguished at certain frequency components. There are several ways of performing spectral decomposition of seismic data in terms of the mathematical...
Attribute Analysis of Mid-Continent Washes, AAPG EXplorer, April 2015 By Ryan Fairfied & Renjun Wen
Attribute Analysis of Mid-Continent Washes The Anadarko Basin granite wash play has been considered difficult to interpret both geologically and geophysically. Consequently, the application of seismic attribute analysis to mid-continent washes has not been widely published. SM Energy’s mid-continent granite wash asset covered a portion of a prolific Missourian age...
Correlation of Vertical Permeability and Volume of Shale in a SAGD Oil Sands Reservoir
SBED Software Assisted with Vertical Permeability in SAGD Project Geomodeling’s SBED product services were used for a steam assisted gravity drainage (SAGD) permeability project by an oil sands operator. Highlights of this permeability study follow, as well as a link to the published SPE Paper. From a producing McMurray Formation...
Geomodeling AttributeStudio™ 7.4 Release
Real Seismic Wavelet Transform: A Breakthrough in Spectral Decomposition for Reservoir Characterization Geomodeling Technology Corp. has released AttributeStudio™ 7.4. This release includes a new Spectral Decomposition Algorithm, Real Seismic Wavelet Transform (RSWT). RSWT uses the extracted seismic wavelet rather than the mathematic wavelet used in Continuous Wavelet Transform (CWT). The extracted...
New Spectral Decomposition Method in AttributeStudio featured in AAPG Explorer
A new method for Spectral Decomposition is featured in an article by its inventor, Geomodeling's Senior Geophysicist Rongfeng Zhang, in the Geophysical Corner of AAPG Explorer. Rongfeng's article, "Effective Ways to Eliminate Side-Lobe Effects" describes some of the issues associated with Spectral Decomposition that can result in self-related events on...
Spectral Decomposition Article from Geomodeling Featured in AAPG Explorer
Spectral Decomposition aids in Seimic Interpretation An article by Rongfeng Zhang, one of our expert geophysicists here at Geomodeling, is featured in the Geophysical Corner of the AAPG Explorer this month. Rongfeng's article, "Finding the Value in Spectral Decomposition," reviews the mechanics of Spectral Decomposition and how it aids...
Recent Academic Research Using SBED
Using SBED to investigate Permeability Modeling of Heterogeneous Reservoirs Geomodeling actively supports Universities and Consortia that have applications for our software. Three very interesting graduate student thesis projects have been completed over the past two years involving use of SBED to investigate problems in permeability modeling of heterogeneous reservoirs. "Estimation...
Improving Reservoir Characterization and Simulation With Near-Wellbore Modeling
New reservoir characterization methods are needed to integrate multiscale exploration and development data, particularly at the interface between well and field models. In this paper, we illustrate a novel workflow involving high-resolution near-wellbore modeling (NWM), which allows us to accurately include seismic, wireline data, image logs, and well core logs...
AVAZ Vector Visualization
AttributeStudio™ from Geomodeling includes breakthrough features for fractured reservoir characterization using visualization and analysis of AVAZ, VVAZ, and other directional attributes. Anisotropic gradients and velocity differences captured by directional seismic attributes such as AVAZ and VVAZ can be correlated to fracture density and orientation in unconventional reservoirs. AttributeStudio’s Vector Visualization...
