The GRACE program generates an
optimal correlation between a
dependent variable (say, y) and multiple independent variables (say,
x1, x2, x3 .....x30). This is accomplished through non-parametric
transformations of the dependent and independent variables.A
common application is to correlate core permeability with well logs. More
E-FACIES partitions the well log
data before building
correlation and is based on Multivariate Analysis of Well Logs.
Generally a suite of well logs can provide valuable but indirect
information about mineralogy, texture, sedimentary
structure, fluid content and hydraulic properties of a reservoir. The
distinct log responses in the formation represent electrofacies
that often can be correlated with actual lithofacies
identified from cores, based on depositional and diagenetic
characteristics.
S3D is a 3-D streamline simulator
for tracer flow and
two-phase (oil-water or miscible flooding)
displacement. The approach comprises of two steps: generating
streamlines in 3D space and then solving the 1D equations
analytically or numerically along the streamlines. The important
features of TRACE3D include Field–scale waterflood
simulation, Miscible flooding capability, streamline-based
integration of pressure and multiphase production data into geologic
models and optimal rate allocation.

The Fast Marching Method (FMM) is
a novel approach to calculate drainage volume and well performance in
shale gas/ tight oil reservoirs. FMM can efficiently provide us with
solution of the pressure front propagation without resorting to
detailed fluid flow simulation. It can also be utilized in computing
and visualizing the time evolution of the well drainage volume for
multi-million cell geologic models in seconds.

SPADES
(Swift Production Data Analysis and Diagnostics Engine for Shale
Reservoirs)
is a model-free production data analysis tool, based on the novel
w(τ)
formulation. SPADES facilitates flow diagnostics and characterization
of
complex hydraulic and natural fracture geometry in shale and tight
reservoirs.
Features include detailed flow geometry and flow regime
characterization and
easy-to-use workflow for rapid selection of re-fracturing candidates.
Fast Marching Method (FMM)
is a
new paradigm for modeling
unconventional reservoirs. It is based on a high frequency asymptotic
solution
of the diffusivity equation in heterogeneous reservoirs. The high
frequency
solution leads to the Eikonal equation that governs the propagation of
a
‘pressure front’ in the reservoir. The Eikonal equation
generalizes the depth
of investigation for heterogeneous and fractured reservoirs and
provides an
efficient way to calculate drainage volume, pressure depletion and well
performance. The major advantages of the proposed approach are its
simplicity,
intuitive appeal and computational efficiency. The currently released
version
of FMM is a Petrel plug-in, where the plug-in will collect input data
and file
for running the Fast Marching Method and use petrel as the
visualization tool.
DESTINY is a multi-purpose
software for streamline tracing, history matching, reservoir management
and development. DESTINY can be run in two different ways: (1) As a
standalone launcher and (2) as a plug-in with the Petrel reservoir
engineering suite. The tool post-processes numerical simulation results
from ECLISPSE, FRONTSIM, VIP and CMG to provide intuitive visualization
of drainage
and swept volumes as well as reservoir flow units and inter-well
interactions for improved reservoir analysis and management.
SmartFlood
(Optimal Rate Management) is a software designed based on an
implementation of a streamline-based waterflood
sweep
efficiency
maximization approach proposed by Alhuthali (SPE 102478) .
The
approach relies on equalizing the arrival time of the
waterfront at all producers within selected sub-regions of a waterflood
project
under operational and facility related constraints. A major advantage
of this
approach is the analytical computation of (i) sensitivities of the
front
arrival times at the producers to well production/injection rates and
(ii)
gradient and Hessian of the objective function, which
The
intent and scope of SWIFT is to provide high resolution upscaled
simulation
models. The current version of SWIFT utilizes a statistical error
analysis for
the design of the coarsened simulation layering scheme derived by
grouping
layers of the high resolution geologic model. The SWIFT coarse layer
design is
based upon an estimate of the impact of heterogeneity on multiphase
flow
frontal motion. SWIFT is delivered as a plug-in for Petrel reservoir
engineering suite or as an executable for non-Petrel users.
GLOBAL
is a multi-purpose
derivative-free optimization software which can be utilized for global
sensitivity
analysis, subsurface model calibration and/or field development
optimization
purposes. Built for both Windows and Linux OS platforms, GLOBAL calls
standard
reservoir simulators (ECLIPSE or CMG) for function evaluations. GLOBAL
is
equipped with a robust proxy model module which significantly reduces
the
number of expensive function evaluation calls. The
source codes (C++ and
FORTRAN) for the programs are available to MCERI members only.
