The SKUA® Reservoir Properties application contains a flexible and dynamic workflow for populating reservoir grids. It offers an extensive suite of geostatistical algorithms for spatial interpolation (mapping), as well as stochastic simulation for modeling geological facies (or any discrete variables) and petrophysical properties, such as porosity and permeability (or any continuous variables).
The Facies Modeling workflow includes a flexible object-based stochastic simulation algorithm, and an efficient multiple-point simulation algorithm (MPS) Impala (developed in collaboration with Ephesia Consult) for geologically realistic facies models.
A post-processing workflow provides tools for summarizing and analyzing simulation results, together with decision-making support tools such as volumetric map computation and connectivity analysis.
A water saturation workflow lets the user define reservoir compartments, either manually or by looking at the juxtaposition or pressure differences across faults. In each compartment, saturation functions can be defined as a function of rock material and height above contacts.

Reservoir Properties
-
A dynamic workflow guides users systematically through an interactive sequence of steps in which parameters are requested as needed. The workflow enables easy scenario management, flexible sensitivity analysis, quick model updates, and contextual note taking, including snapshots.
-
Geostatistical algorithms: A large number of industry-proven geostatistical algorithms are provided for interpolation and stochastic simulation.
-
Multiple constraints: The Reservoir Properties application offers a variety of options to easily incorporate multiple secondary data, resulting in realistic reservoir models.
-
Customizable algorithm combinations: A user-defined sequence of modeling steps allows users to combine fit-for-purpose algorithms.
-
Flexible parameter specification: All parameters can be specified as spatially varying to account for geological non-stationarity.
-
Post-processing: Users can summarize and extract relevant information from multiple realizations of the reservoir model, and infer threshold probabilities and other decision-supporting statistics or metrics.
Facies Modeling
-
A utility to interactively draw a geological body for use in the object-based stochastic simulation algorithm,
-
A utility to create training images for MPS by drawing bodies observed on the seismic data. This drawing can be done in the paleo-domain display unique to SKUA..
-
Fast, generic, object-based simulation using pre- or user-defined geological shapes in which all object parameters can vary spatially
-
Efficient, parallelized, multiple-point simulation using 2D or 3D training images
Water Saturation
-
Compartment definition with SGR information
-
Saturation functions (J Functions, etc.)

Reservoir Properties
-
Flexible options such as spatially varying parameters (variograms, mean, etc.) and smooth transitions between facies lead to more geologically consistent and robust reservoir models, for a better understanding of reservoir mechanics.
-
Facies and petrophysical models are built by simultaneously considering different types of information: Well data, trends, multiple (seismic) attributes, conceptual geological drawings, etc. The data integration features included in Reservoir Properties lead to more reliable reservoir models.
-
The dynamic workflow ensures repeatability, smooth project transfer, ease of use, and an audit trail.
-
More accurate and reliable models promote a better understanding of reservoir connectivity for evaluating in-place resources and forecasting production, resulting in optimized development plans and facility design.
Facies Modeling
-
A toolbox of facies modeling algorithms enables the construction of geologically realistic reservoir models that honor geological concepts, wells and seismically derived constraints.
-
The breadth and flexibility of the available options allow an efficient investigation of alternative geological scenarios.
