Post Petrel 2010.1 Modules & Cores Overview
As I noticed a lot of confusion about the functionality of the different Petrel 2010 modules and cores, I created this overview for my manager. I thought I'd share it with you guys!

Petrel Cores:

Petrel uses several different cores that allow users to use different modules and perform certain workflows. A listing of the different cores is given next.

Geoscience Core system:
Online help system, 2D and 3D visualization, data import, histogram and calculator for well logs, creating & editing well tops, digitizing & editing polygons, fault modeling with 3D editing, 3D pillar gridding, make horizons, zonation building (isochores) and fine-scaled sub-zonation in 3D grid, filtering functions, Allen diagrams, editing 3D grid, generation of flow simulation grids (geometric scale-up from fine grid), advanced volume calculations, grid and line operations, general 2D gridding, stereo imaging, general and well intersections, spreadsheet reports output as text files, Workflow editor for automated model updates and mapping processes. Scaled map & cross section plotting.

Reservoir Engineering Core system:
From the new Reservoir Engineering Core module, you can build ECLIPSE simulation models directly from your geological models; add fluid properties, well completions, production history and event scheduling. Organize your geological realizations and development scenarios into cases and select and launch the appropriate ECLIPSE and Frontsim simulator and analyze your results.

Combined Core system:
The Combined Core module includes the functionality of both the Geoscience Core and the Reservoir Engineering Core

Data and Results Viewer:
The Data and Results Viewer provides easy access for viewing well and seismic data, reservoir interpretations and simulation results. An ideal tool for simulation engineers, managers, stakeholders and even shareholders, the viewer provides viewing access to all Petrel data items found in a project, without the necessity of learning individual Petrel modules.

Petrel Modules:
The following modules are available in petrel and a listing of their functionality and required cores is given next.

Petrel Geophysics
Fully integrated with the geological and engineering tools, the Petrel seismic toolkit allows for rapid 2D & 3D interpretation. Sample your seismic data directly into your 3D reservoir model to predict pay and bias reservoir property distribution using a geo-statistical approach. An extensive library of attributes and volume rendering techniques can help identify hydrocarbon indicators and fracture patterns.

Seismic interpretation (Geosciences Core or Combined Core):
Import of 2D & 3D SEG-Y or ZGY data, 3D visualization of seismic inlines, crosslines, timeslices and random lines. Generation of simple seismic attributes, digitizing fault pillars/fault sticks, guided-, 2D & 3D seeded auto-tracking and manual interpretation of reflectors on vertical seismic intersections, digitizing fault planes on timeslices, QC and re-interpretation of imported line data, seismic color table including discrete color ranges, advanced filtering options on value ranges including transparency, resampling of imported data (cropping). Traditional 2D interpretation window with bitmap, and/or wiggle display.

Domain conversion (Geosciences Core or Combined Core):
Node by node depth conversion of the structural 3D grid, average velocity for selected zones are used based on constants, linear velocity functions, velocity maps or a combination of these, depth conversion along pillars or vertically, spreadsheet report.
Multi-trace seismic attributes (Geosciences Core or Combined Core and Seismic interpretation):
Generation of advanced seismic attributes from imported seismic volumes (e.g. graphic equalizer, structural smoothing, variance, Iso-frequency, iso frequency, t*attenuation, Ant-tracking).

Seismic volume rendering and extraction (Geosciences Core or Combined Core and Seismic interpretation):
Any 3D seismic attribute volume can be extracted from a SEG-Y/ZGY cube. Different degrees of transparency can be applied. The seismic volume can be rendered in 3D and visualized together with any other data available in Petrel. State-of-the-art volumeblending technology is used in Geobody interpretation to quickly isolate, extract, and integrate a body directly into a property model for true 3D volume interpretation. This allows users to interactively blend multiple seismic volumes, isolate areas of interest, and then instantly extract those areas into a 3D object called a geobody.

Seismic sampling (Geosciences Core or Combined Core and Seismic interpretation):
Display of seismic data (using intersections) and QC of the seismic data within a 3D grid, depth conversion of a seismic volume (requires the Domain Conversion module), creating a seismic property by sampling any seismic attribute into a 3D grid, extract seismic data to an attribute map that can be draped over a surface.

Automated structural interpretation (Geosciences Core or Combined Core and Seismic interpretation):
An automated fault interpretation workflow allowing interpreters to spend time understanding the trends of fault surfaces and to make correlations from automatically extracted fault patches from Petrel-generated Ant tracking cubes.

Petrel Geology and Modeling
A full suite of reservoir characterization modules include the ability to generate well correlation panels, perform traditional mapping and plotting techniques and 3D reservoir modeling, seamlessly integrated with the simulation environment. The Workflow editor tool allows for rapid model updates reducing project cycle time and maximizing efficiency.

Well Correlation (Geosciences Core or Combined Core):
2D well correlation display, correlation of formation and facies tops, dynamic link in all displays; 2D, 3D and Spreadsheet, extensive display options, various subdivisions of tops and facies with legends.

Facies modeling (Geosciences Core or Combined Core):
Scale up of well logs, sequential indicator simulation, stochastic fluvial object modeling, adaptive channel modeling with well conditioning, Multipoint Facies modeling, deterministic interactive facies modeling permits editing and adding facies objects by using interactive drawing tools, zone by zone modeling with options to model several zones together.

Petrophysical modeling (Geosciences Core or Combined Core):
Scale up of well logs, deterministic petrophysical property modeling, stochastic property modeling using algorithms from GSLib and improved inhouse versions of Kriging, histograms of well data & generated model, geometrical property modeling, 4D property player, geometric and property value filter, interactive editing of property values, generation of average and net maps, display properties directly in a well section, scale up of properties, export of 3D property models (filter sensitive).

Petroleum Systems Quick Look (Geosciences Core or Combined Core):
Lets geoscientists perform charge modeling for scouting evaluation and ranking of plays and prospects. This creates a connected workflow for generalists and specialists. Petroleum systems experts can perform full analysis of charge risk with the advanced functionality in the PetroMod software.

Structural and Fault Analysis (Geosciences Core or Reservoir Engineering Core or Combined Core):
Extraction of fault cell faces along fault surfaces in the 3D grid. Calculation of permeability, thickness and shale gouge ratio along the fault. Calculation of transmissibility multipliers based on fault properties and grid permeabilities. Export of transmissibility multipliers in ECLIPSE format.
Discrete fracture Modeling (Geosciences Core or Reservoir Engineering Core or Combined Core):
Discrete Fracture Networks (DFN's) can be generated and visualized in Petrel, fracture attributes can be assigned to each fracture plane and the fracture attributes can be upscaled using Golder algorithms to grid properties (Permeabilities, Porosity and Sigma Factor), fracture grid properties can be used directly in Define simulation case in Petrel for Dual Porosity/Dual Permeability simulation.

Petrel Reservoir Engineering
With your reservoir model in place, use the Petrel simulation workflows to perform ECLIPSE simulation, reduce uncertainty and assist in future well planning. Advanced up-scaling techniques allow you to recreate geologically accurate models for full reservoir simulation.

Advanced Gridding and Upscaling (Geosciences Core or Reservoir Engineering Core or Combined Core):
The Advanced Upscaling module has now been placed on maintenance mode. A new module, Advanced Upscaling and Gridding, contains new simulation gridding technology supporting Local Grid Refinements (LGR's) and IJK stair-step gridding, as well as the upscaling functionality of the Advanced Upscaling module. Features include a wide range of upscaling techniques for sampling fine scale grids into coarser simulation grids. Includes full tensor upscaling for permeability, which runs simple simulation in each of the coarse cells to calculate effective permeability in each direction. Flexible options for the solver used, skin cell definition, output orientations and the consideration of porosity and N/G properties.

Frontsim Locked (Reservoir Engineering Core or Combined Core):
Inclusion of the ECLIPSE FrontSim streamline simulation technology enables better workflows for ranking geological models. It is an important step in the iterative workflows in Petrel for estimating uncertainties and to better understand which models to base decisions on. The module and the user interface is adjusted and conformed to fit with the 3D modeling workflows in Petrel.

History Match Analysis (Reservoir Engineering Core or Combined Core):
Perform history-matching studies on multiple ECLIPSE reservoir simulation runs in an effort to isolate the best or most likely geological realization.

Great work! thanks for this. All those modules can be confusing. Especially when negotiating which modules are needed with my manager. This is an easy print out. Do you have (approximate) pricing as well?

Would appreciate it.
