Upscaling Well engineering Strategies

Page 2: 10 Appendix

Dual porosity – Dual permeability

Fluids exist in two interconnected systems

Reality

Simulator approximation

Page 3: 10 Appendix

Dual porosity – Dual permeability

Create fracture network model using the Create discrete fracture network process

Scale up fracture network properties: porosity, permeability (3 or 6 tensors), sigma

Page 4: 10 Appendix

Dual porosity – Dual permeability

Add fracture system to simulation:

2. Drop in fracture properties and the dual porosity matrix-fracture coupling transmissibility

1. Select simulation type

3. Add relative permeability curves for the Fracture system

4. Set Advanced dual porosity settings (no DP multiplier and Gravity drainage)

Well region property

You can use the Geometrical modeling tool to make a region around a well.

Page 6: 10 Appendix

Sector modelingCapture the boundary conditions for a region

Page 7: 10 Appendix

Sector modelingInsert a sector model

Once the full field model has run, the boundary condition for the region is stored on the Models pane.

Right click the full field case in the Cases pane and select Insert sector model.

Page 8: 10 Appendix

Sector modelingRun a sector model

Open the sector model in the Define simulation case model, and drop in the boundary condition captured during the full field run.

Page 9: 10 Appendix

Hysteresis

Hysteresis: When the curve used to determine the rock properties is a function of the history of the rock and a function of the direction of the change in the saturation.

Page 10: 10 Appendix

Hysteresis

Select drainage relative permeability curves and imbibition relative permeability curves in the Functions tab

Drop in saturation functions from the Input pane

Import a case - Select file

Right click in the Cases paneand select Import (on tree)…

1. Set ‘Files of type’ to beECLIPSE/FrontSim data and results.

2. Select .DATA, or .EGRID etc. and Petrel will locate the other files if available

Page 12: 10 Appendix

Import a case - Selection of files

Petrel will locate all necessary files,

if available. You can also makeyour own selection

The Simulator is auto selected based on the data file.

Make sure it is correct because it cannot be changed after import.

Page 13: 10 Appendix

Import a case - Units issues

The units can not be changed after import

You will receive a warningif the project you import does

not match the Unit system of your current project.

Click on Change if your current project is empty.

Page 14: 10 Appendix

Import a case – Petrel objects

Well data from

RESTART files in the Input pane

3D Grid and properties in the Models pane

Summary data in the Results pane

Simulation case added to the Cases pane

Page 15: 10 Appendix

Import a case - Convert to Petrel case

You can convert the imported case to a Petrel case. Right click the case and select Convert to Petrel Case

Most items are converted including:• Fluid model• Rock physics functions• 3D grid properties

The development strategies are NOT converted

Case managementRemote job submission

It is possible to submit jobs from Petrel to a Linux/Unix

computer

To do so you must• Install support for remote simulation• Configure Petrel for remote job submission• Define queues in Petrel
