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 makes it computationally efficient and suitable for large field cases.
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.More information about GLOBAL
