Three-Dimensional Simulation of Small-Scale Heterogeneity in Tidal Deposits
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...

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...

Estimation of Reservoir Heterogeneity from the Depositional Environment in Reservoir Characterization of a CHOPS Field
The major challenge in reservoir characterization is to estimate the effective porosity and the permeability of the reservoir due to reservoir heterogeneity. Often the vertical and the horizontal permeability are not considered separately in 3D...

SBED Biogenic Structure Modeling
SBED™ Biogenic Structure Modeling accurately simulates the activities of burrowing organisms on reservoir facies at the lamina scale and estimates their effects on petrophysical properties using flow-based upscaling. Bioturbation within a substrate can...

Estimation of geocell permeability based on small-scale sedimentary structures in the Brent Group on the Gullfaks and Oseberg fields
Permeability is very difficult to estimate, mainly because it is very scale- and direction dependent. For instance, from permeability measured in core plugs to permeability estimated from well tests, there is a big difference in scale. How to...

Estimation of geocell water saturation based on small-scale structures in the Brent Group on the Oseberg and Gullfaks fields
Water saturation in reservoir rocks is highly dependent on petrophysical parameters as permeability, porosity and the amount of clay and shale in the sandstone. Saturations are important for static hydrocarbon volumes and for...

Combining Seismic Imaging with Geologic Process-Guided Modelling to Improve Channel Reservoir Characterization
Accurate identification and portrayal of a channel system is rarely easy. Exploiting it is even harder. The depositional processes and crosscutting relationships do not leave behind simple linear features with welldefined boundaries. Conventional examination of...
