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...
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...
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...
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 geo-cellular models and in the reservoir simulations. Conventional reservoir modeling extrapolates all of the small-scale data to full-field scale...
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 add to sedimentary heterogeneity and alter horizontal and vertical permeability. Understanding the subtle changes in permeability that...
Bioturbation and Its Effects on Permeability in Wave-Dominated Shoreface Rocks of the Spring Canyon Member, Blackhawk Formation, Utah, USA
Burrowing organisms displace and mix sedimentary grains by burrowing, feeding and relocating. Their activity within the substrate can add to sedimentary heterogeneity, but more importantly alters horizontal and vertical permeability. Understanding the subtle changes in permeability that result from biogenic structures within sediments is an important concern for operators working...
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 compare these correct and apply further in reservoir computer models, is a...
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 saturation-dependent flow parameters, such as relative permeabilities. Methods used today to estimate water saturation are usually based...
