Import and DisplayObjectives

Import and display Dipmeter data.

Visualize fractures in 3D along Well bore

QC and use Spreadsheet actively

Create Tadpole panels for visualizing fracture dips

Create Rose diagrams to check fracture azimuth

Optional: Import and visualize image logs

Import and DisplayFracture well dataImport Workflow

A full Fracture Modeling workflow in Petrel integrates:

Fracture indicators (well data)

Fracture drivers (seismic and geomechanical properties)

Well data and attributes involves:

Point data (dip, azimuth etc.)Fracture logs (trace length, frac density, aperture etc.)

Image logs (FMI, core etc only for visualization)

Assumptions:

Dips have been picked

(not possible in Petrel)

Fracture logs have

alreay been processed

Check Spreadsheetto get an overview of all imported attributes.

The spreadsheet can be filtered by well.

Import and Display4. Create Tadpole tracksFracture Dip

Add a new tadpole track in Well section

settings. Select fracture points using dip

azimuth and dip angle (0-90 deg).

The tadpole will automatically be displayed

in the active well section


8/12

Import and Display5. Create Rose diagramsFracture Dip orientation

Create new Rose diagramtrackfrom Well section settings.

The Rose diagram will

automatically be displayed in the

active well section.

Tips:

The rose diagrams

can be displayed

between well tops

or at given depthintervals


9/12

Import and Display5. Create Rose diagramsFracture Strike orientation

Dip azimuths can be displayed aspoints.

Show Strikeinstead of dip azimuth.

Import and Display6. Image LogImport (optional)

When importingimage logslike core and FMI, they have a different import dialog from

conventional logs. Rename all logs with MD values in the name to make the procedure easy,

and save as.BMPfiles.). They will be saved as separate Global well logs

Tips:

Import all images at once. Set startand stopMD

as there is no depth referencing for this log type.


11/12

Import and Display6. Image LogDisplay (optional)

A global image log is stored for each well (if all logs are imported at once), separated by redlines (control points). Update the Well section template using the image logs for each well.
