Flow in a reservoir is mostly controlled by the connectivity of extreme permeabilities (both high and low) which are generally associated with marked, multiple-scale geological patterns such as fluvial channels. Accurate characterization of such patterns requires multiple-point correlations that are much beyond the reach of the two-point correlations provided by...
A petrophysical evaluation of tidal heterolithic deposits: Application of a near wellbore model for reconciliation of scale dependent well data
The main goal of this thesis, A petrophysical evaluation of tidal heterolithic deposits: application of a near wellbore model for reconciliation of scale dependent well data, is to give a better and less uncertain estimate of porosity and permeability in a challenging reservoir type. This is accomplished through an integrated...
Seismic Waveform Classification: Techniques and Benefits
Seismic waveform shape and character can define facies and reservoir parameters with far greater detail than traditional time and amplitude mapping. Modern techniques using waveform classification make it possible to define and map subtle changes in seismic response and to match them to subsurface information. Waveform classification can also be...
Permeability Rescaling And Near-Wellbore Modeling Of Heterogeneities In Lower Jurassic Tidal-Influenced Tilje Formation, Heidrun Field
The Lower Jurassic Tilje Formation constitutes an important reservoir in the Heidrun Field. Reservoir characterization of its strongly tide-influenced deposits is challenging due to the high degree of heterogeneity. This is especially true for the estimation of permeability data from different scales (core plug measurements, log data and well test...
Permeability Estimation Functions Based on Forward Modeling of Sedimentary Heterogeneity
Effective permeability in the inter-well reservoir volume is notoriously difficult to estimate due to its scale dependence and sensitivity to heterogeneity. Using stochastic models of realistic 3D sedimentary heterogeneity at the 10cm to 10m scales, we established a series of functional relationships between effective permeability, bedding type and volume fraction...
