Start up Petrel (let me know if you find 2012.3)

Visit the class web site at

First, lets check to see if your accounts and software are working properly.

Getting into Petrel today (& next Monday)To do list

Intro to Petrel Setting up a project

Importing well data Basic view manipulation Importing formation tops More on data display and formatting Make-edit surface Edit map display color

Bringing seismic data into your project (Monday) Crop and realize your volume Viewing your seismic data Odds-n-ends

Bring up Petrel

The entry window should come up with

the number of packages currently available for use>

click OK

Basic Petrel project window layout

Inputs Models Results Templates

Processes Cases Workflows Windows

Starting a new projectProject > Project Settings

Under Units and Coordinates > Select Field for your units system

Looking into the heart of the Stratton field

We have to import data and build the project database.

Go to Insert > New Well Folder

Your input tree should now include a wells drop down list.

RC > Import on Selection

The ascii import file has a simple structure. Note that the column titles are listed following the BEGIN HEADER line

Familiar well numbers from

StrattonUndefined value

KB & TD

View Petrel Import File Structure

Petrel reads the header list and should follow the format of your input ascii file

Display window manipulation basics

Ctrl + shift > mouse up-down, left right to zoom in and out

Ctrl or shift > mouse up-down, left right to move the entire view up or down

Change vertical scale

Wells > Settings > Style >experiment with path and symbols parameters


Drop down the wells in the list and RC > Well Manager to see Petrels version of the well input file

You can QC to cross check posted values with your import data set

The Stratton data set also comes with pre-picked formation tops. Follow below to import

RC>

Petrel well tops (ASCII)(*.*)

MD Type Surface

Basic format of formation top input file

Check the well tops drop-down check box.

Ctrl +shift > then move mouse to zoom in

Ctrl (or shift) + mouse movement up and down to position the window vertically

RC> Well Tops folder > Spreadsheet

RC > Settings > Color as Horizon and change fonts

Provides some color contrast in your display

Well come back to this next Monday for a review


Processes > Utilities > Make Edit Surface

& more

Utilities > Make/Edit Surface > structure contour map

Not yet?

Make/edit surface selections & activate the map in your input tree

Fine tune the color mapping

You should have map similar to the one below. Adjust the vertical exaggeration to see structural features in 3D relief.

Under the style tab > Adjust contour labels & explore other function tabs

Back to basin structuresHarding and Lowell Figure 23 (top)


Typical structural interpretation for a down-to-basin, growth, detached normal

Harding and Lowell Figure 23 (bottom)


Typical structural interpretation from deeper in the section reveals increased landward dip or rotation of normal fault blocks into the master normal fault..

Harding and Lowell Figure 24


Interpretation along AA (Figure 23) reveals increased syndepositional movement (fault offset during deposition) with depth . Note thickening into the deeper faults to the southeast (toward A). Growth was much more significant in the late Oligocene and very limited during the miocene.

Missed opportunity?

Take a closer look at the section and log interpretations


Complete the 2nd contouring exercise and hand in Monday

Exercise 3 Petrel intro


Take some time to review procedures and bring questions about this to class next Monday. Exercise 3 will be due next Wednesday.


1. Turn in contouring exercise (exercise 1) Next Monday

2. Do the second contouring exercise handed out today and bring in for discussion on Monday

3. Get started on the Petrel intro exercises and bring questions to class on Monday

4. Continue looking over the review papers on contouring and structural styles.

5. Its not too early to start thinking about the semester project and what youd like to do for that. Nail something down early in the semester.
