Validating Workflows with Pore-Scale Modelling and Fine-Scale Geology for Water Saturation Interpretation
Future workflows for water saturation interpretation in heterogeneous intervals, should take the heterogeneity into account in a robust manner. We want fine-scale geology to be modelled realistically, down towards mm-scale when appropriate, and populate these models with properties from pore-scale modelling. The geologically realistic models can then be upscaled for...
Increasing Geological Accuracy in Reservoir Models through Process-Oriented Modeling
An important task in constructing digital reservoir models is the capture of geological detail with sufficient resolution to reduce the uncertainty inherent in interpolation between discrete data points. Even the most sophisticated mathematical or statistical reservoir modeling algorithm, however; remains ignorant of the processes by which reservoir strata are deposited....
Combining Seismic Imaging with Geologic Process-Guided Modelling
Improve Channel Reservoir Characterization By Combining Seismic Imaging with Geologic Process 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 poststack seismic reflections leaves...

Multiscale Data Integration in Characterizing and Modeling a Deepwater Turbidite Reservoir
Information from cores and wireline logs, processed according to different methodologies, were integrated to provide a consistent facies classification, petrophysical characterization and 3D geological model of a deep-water turbidite reservoir in the Gulf of Mexico. A number of sedimentological facies (sed-facies), either heterolithics or single-lithology, were first identified on cores...
Modeling of Intra-Channel Belt Depositional Architecture in Fluvial Reservoir Analogs from the Lourinha Formation, Portugal
Fluvial channel and channel belt deposits are commonly represented in subsurface reservoir models using an object-based approach that stochastically places a channel facies in a background of overbank deposits. The internal heterogeneity within the channel is usually represented by adding intra-body trends to the petrophysics. The aim of this study...
Pore Space Estimation, Upscaling and Uncertainty Modelling for Multiphase Properties
This paper reports results from a sensitivity study aimed at understanding and evaluating uncertainty in a pore-to-field workflow. A methodology to identify and quantify uncertainty at different scales and to propagate, or upscale, this information to the reservoir simulation model has been developed and tested. A case study is presented...
Core-Data Preprocessing To Improve Permeability-Log Estimation
Two techniques of preprocessing data from core plugs have been investigated to enhance the quality of synthetic permeability estimation from conventional logs by use of artificial neural networks (ANNs). A first technique consists of “cleaning” the core-plug data set by removing the measurements deemed log-incompatible (i.e., those from plugs corresponding...
Improving Net-to-Gross Reservoir Estimation with Small-Scale Geological Modeling
Geoscientists have often been frustrated by the arbitrary assignment of petrophysical log cut-offs to define reservoir intervals capable of hosting producible hydrocarbon. The traditional practice is to derive "pseudo-permeability" from well logs such as gamma ray, density, and sonic. However, this indirect approach can introduce large errors in estimates of...
