Schlumberger Mapping Datasets


Schlumberger Public

Module 1 Mapping Datasets There are six mapping applications (mappers) in this version of OilField Manager (OFM):

Bubble Map Grid Map Contour Map (2D-Map) Surface Map (3D-Map) Scatter Plot Map XY Plot. They all share the same dataset and can work synchronously in animation. Once the dataset exists, it can be called from and used in any of the mapping applications.

Learning Objectives In this section, you will be introduced to the fundamentals of mapping datasets as well as the powerful features of OFM mappers. You will successfully learn how to perform the following procedures within this workflow:

Create a static dataset Create a monthly/daily dataset Create a sporadic dataset Modify a dataset

Lesson 1 Static Datasets Static data includes the following information:

Location data Completion date Initial pressure Total depth Perforations Porosity Initial rate and pressure Drilling cost Location

NOTES

Schlumberger Bubble Maps


Schlumberger Public

Module 2 Bubble Maps The Bubble Map provides an excellent tool for OFM users to visually present data on a geographical map. The bubbles (which come in many different shapes, i.e., circle, square, triangle, pie) are displayed at the entities locations, therefore this type of analysis should be used at a data level that has XY coordinate information. Because the datasets themselves are date-dependent, OFM also supports map animation over time, which gives users a way to observe the historical development of the studied area.

Learning Objectives In this module, you will learn to set up a customized bubble map and become familiar with the options available from the Properties pane. You will successfully learn how to perform the following procedures within this workflow:

Set up bubble map single variables Refine the map display Change color scales Set up bubble map multiple variables Work with time Animate the map

Lesson 5 Bubble Maps with Single Variables

In this lesson you will learn to set up Bubble Map single variables.

Exercise 8 Setting up a Bubble Map with a Single Variable

To set up a bubble map with a single variable:

1. From the Filter pane, expand the Table Data node then select the Monthlyprod table.


3. Select the Monthly dataset, located in the Datasets section of the dialog.

4. Click Open. The bubble map displays. 5. In the Properties pane expand Data and locate the Variables

sections.

Lesson 9 Time Step and Map Animation

The bubble map is very time dependent. The time (step) options are accessible from the Step menu. This menu is local and only available when a mapper window is open. Familiarize yourself with the Previous Date and Next Date menu commands. You can use these commands to navigate through time.

Exercise 14 Working with Time Step and Map Annimation

To use time step and map animation:

1. From the Step menu, perform the Previous and Next date operations by selecting the desired option. Select Step > Select Date. The Select Date dialog displays.

2. Select 12/1/1999 and click OK. The bubble map displays with

the date shown.

NOTE: The Date display format depends on the date frequency of your mapper set (dataset). Since you are currently using a monthly dataset, only the year and the month display. The default date step (increment) is your date frequency (i.e., month-by-month). You can change the time step by selecting Step > Increment and entering your desired duration. This setting does not affect the animation setting.



Schlumberger Public

3. Select Step > Increment. The Set Step Increment dialog displays.

4. Set the Step increment to 3. This means that each time you

click the Next/Previous Date; you skip two months and carry out a quarterly navigation. Click OK.

5. Click the Next Date and/or Previous Date buttons and observe the date display.

One of the interesting features of the OFM mapping applications is the ability to animate the mappers over time. OFM asks for a start date, an end date, the increment (and more). It then will generate a movie automation that represents the historical development of your studied area.

6. Select Tools > Animate with your bubble map open. The Animation Control dialog displays.

7. By default, OFM will perform the animation starting from the

absolute start date of the mapper set to the absolute end date. The default step increment is 1, and the default pause time is 0.1 second. The default time direction is going forward. Keep everything unchanged here and click OK. It may take a while to complete the animation.

NOTE: The step increment is applied to the animation.

NOTE: Press the Space Bar once to pause the animation. Press the space bar again to resume the animation. Press the ESC key to stop the animation. There are also animation controls at the top of the map window that will assist you in animating the bubble map



Schlumberger Public

8. Change the Pause time to 0.2 seconds (2 of 1/10 second). 9. Click OK. The animation restarts.

Lesson 10 Bar Charts in the Bubble Map Module

A bar chart can be used rather than a bubble map to Group by a category at which each bar chart is created and the Then group by field refers to the level at which each bar's calculated variable is displayed.

Exercise 15 Creating Bar Charts in Bubble Map

To create bar charts in the Bubble Map module:

1. From the Filter pane expand the Category node, then Lease and select BERRINGER, TRAMMEL, and WALLACE.

NOTE: Depending on your specified start date and step, the animation could stop before your specified end date.



Schlumberger Public

2. Select the Reservoir node and select a few of the reservoirs. 3. Select Analysis > Bubble Map. The Open Bubble Map

dialog displays.

4. Click New. In the Title field type Bar. 5. Select the following variables from the Project Variables

section of the dialog:

Gas.cum Oil.cum



Schlumberger Public

6. Click Next. Select LEASE from the Group by list field.

7. Select the Then group by checkbox. This action enables the

list field.

8. Select RESERVOIR from the list field. 9. Click Retrieve source dates.



Schlumberger Public

10. Click Next. In the Dataset field type Bar.


The map displays three leases of interest (BERRINGER, TRAMMEL, and WALLACE). Cumulative oil and gas production are represented as individual bars with their corresponding values for each reservoir within the leases. Please note the bars represent absolute values of the selected calculated variables.



Schlumberger Public

Lesson 11 Animation Controls Like all other mapping modules, these bar charts can be animated over time. Use the horizontal slider at the top of the window in the left hand corner near dates to see the animation or you can use the desired controls to animate the bubble map over time.

Alternatively, you can choose Tools > Animate. The Animation Control dialog displays.

This dialog enables you to see the effect of animation over the user specified date range (this feature will be further discussed later).

Repositioning Bubbles for Clarity

The individual bubbles at each XY location are no longer fixed. This enables you the flexibility of moving the objects to any location on the map. This feature is particularly useful for those fields with a high well density where the bubbles often overlap each other.

(Screen capture for display purposes only)

The bubble map on the right shows the actual positions of the bubbles as defined by the well coordinates. The bubble map on



Schlumberger Public

the left illustrates the bubbles that have been repositioned from their actual positions for the purpose of clarity.

1. Right-click on the bubble map. A shortcut menu displays.

2. Seslect Move Shapes. A checkmark is displayed to the left of this option, indicating that it is enabled.

3. Select the shape you want to move and drag it to the desired

location on the bubble map. A line is drawn from the original location of the object to the new location.

Saving Your Work

There are two aspects of the bubble map you may want to save.

1. Select File > Save As. The File > Save As option can be used if you are not currently working on an open (*.bub) file. Save the file to save the setup.

2. To save the results, select File > Save Image As. You can save the image in several standard graphic formats (bmp, jpg, tiff, emf).

Review Questions Why can you not display Title on a bubble map? What does the animated movie of your bubble map

represent?

What does a bar chart represent on a bubble map? What aspects of a bubble map can you save?


Set up bubble map single variables Refined map display Changed color scales Set up bubble map multiple variables Utilized the animation controls In the next module you will learn about working with OFM grid maps.

NOTE: To disable the Move Shapes command, right-click on the map and select Map Shapes. The checkmark is no longer displayed next to the command.

To restore the objects on the map to their default positions, right-click on the bubble map and select Default Positions

Module 3 Working with Grid Maps

Gridding algorithms have been widely used in the oil industry for a long time. There are many software applications that offer good analytical capabilities. OFM has its own gridding package, providing a reasonable range of useful features. In this section of the tutorial you will learn to create/edit grid maps using different gridding algorithms that OFM provides (i.e., Nearest Neighbor, Cubic Spline, and Kriging methods).

Grid maps share the mapping datasets with other mappers, therefore we do not have to create a dataset for a particular grid map. We will primarily use the Monthly dataset in this chapter.

Learning Objectives In this section, you will successfully learn how to perform the following procedures within this workflow:

Set up grid maps Use grid map tools Use additional grid map features

Lesson 12 Grid Maps Unlike the Bubble Map, only one variable can be used at a time in Grid Maps. The Grid Map is a three-dimensional presentation of the variable displayed, with the other two variables being x and y-coordinates.

Exercise 16 Setting up Grid Maps

To set up a grid map:

1. Open the Demo2007 project .

2. From the Analysis toolbar, click the Grid Map icon or select Analysis > Grid Map. The Open Grid Map dialog displays.

3. Select the Monthly dataset. Do not modify the dataset.

Working with Grid Maps Schlumberger


Schlumberger Public

4. Click Open. A grid map is displayed with the first variable in the dataset.

5. From the Properties pane, locate the Variables Property

section.

6. Locate the Variable property and select Oil.Cum. 7. Leave the Scale Type set to Linear. This is for the color/value

scale.

8. Set the Minimum value to 1 and the Maximum value to 1500. 9. Set Exclude out of range to Yes. Remember, we did not filter

the wells to those that have production. There are wells on the map that have no production data. By setting the minimum value and exclude the values that are smaller than 1, we will filter out non-producing and negligible-producing wells from the map.

NOTE: Locate the Grid section of the Properties pane. Do not change any additional information, however, lets review what those parameters mean.



Schlumberger Public

By accepting the default settings, you are telling OFM to use the Nearest Neighbor algorithm, with a maximum grid size of 50 in each dimension, thus constituting 50x50=25000 grid cells total. OFM performs the Nearest Neighbor gridding based on 5 nearest neighbor values and will search for those 5 neighbor values within a radius of about 3.6x10^6 map units.

In the Bubble Map session, you learned to use the options in the Map Display, Legend, and Color Scale menu commands. Refer to the Working on Map Display section of Bubble Map and change the display settings and color scale settings. Your map should look similar to the one pictured below.

10. Locate the Grid section of the Properties pane. Set the

Technique to Spline, then to Kriging methods and observe the differences in the Grid Map.

11. Change the Technique back to Nearest Neighbor. Change any additional properties and observe the changes in the Grid Map.



Schlumberger Public

12. Locate the Variable Properties section of the Properties pane. Select the cell to the right of Default. This action enables a Default button.

13. Click the Default button to restore the default settings.

Question


Based on what you see on the grid map (step 9 above), what kind of conclusion could you make about which area of the field has high production and which does not?

Other Important Features in Grid Map

1. From the View menu, select Cell Boundaries to enable this feature. The results of this action are pictured below

2. Select the Grid Statistics tab located at the base of the Grid

Map window.

NOTE: OFM enables you to use a combination of parameter settings corresponding to your scheduled technique. However, it is possible to reach the limitation of the algorithm. Always verify your results to ensure this has not occurred.



Schlumberger Public

3. There are 50x50=2500 cells on the map. You can manually count the cells or enable the Trace Grid option from the View menu.

4. Click the very bottom right cell to verify. If necessary, you can resize the output window (Grid Statistics tabbed page) to fully display the information contained in the window. In addition to displaying the total number of cells, OFM all performs some statistical calculations to get the sum (of all 2500 Oil.Cum cell values); their average, the area and volume (remember the three-dimensional characteristics of the grid map).

Exercise 17 Creating/Editing Grid Areas and Control Points

OFM gives you the option to draw your custom grid areas and manipulate cell values by adding control points. In this next exercise, you will learn how to create/edit grid areas and control points.

To create and edit grid areas and control points:

1. Turn off the Cell Boundaries option. 2. Right-click on the Grid Map. A shortcut menu displays.

3. Select Grid Area > New. The draw grid area mode is activated.

4. Start digitizing the grid area by clicking with the left mouse button to draw a boundary. OFM will connect the points and make a polygon as shown below.



Schlumberger Public

5. Right-click and select Done. The new grid area displays.

6. Select the Grid Statistics tab located at the base of the Grid

Map window. You can see the differences the grid area has made. Compare the original grid area.

7. Select the Grid map a right-click. From the shortcut menu,

select Grid Area > Save. The Grid Area dialog displays.

8. Type monthly.ga in the File Name field and click Save.



Schlumberger Public

9. Right-click on the Grid Map. From the shortcut menu, select Grid Area > Exclude. This action will exclude data points outside the grid area when calculating the grid. Take a look at the output window by clicking the Grid Statistics tab.

10. Compare this result and the results obtained earlier. You can see that with the same grid area in both cases, the results are slightly different. It was the result of OFM excluding data points outside the grid area. In the former case, those data points still had the influence on calculations (those values are typically small). In the latter case, those points were completely ignored, resulting in higher average and volume. You can create as many grid areas as you want by selecting Edit > Grid Area > New.

11. Clear the grid area by selecting Edit > Grid Area > Clear. The original grid map displays.

12. Select Edit > Grid Area > Open. The Grid Area dialog displays.Select monthly.ga and click Open. The grid map displays with the area defined in the monthly.ga file.

In one scenario there is a fault along the left side of the field, so the cell values along that fault are close to zero. In another scenario you may know some values. For example, the points belong to another grid area and the values are calculated and proven. The Oil.Cum data calculated from the database and the grid area is the only defining boundary and you cannot take this fact into account. OFM has the Control Point feature that helps resolve this problem.

13. Right-click on the grid map and select Control Points > Add from the shortcut menu. The Control Point Value dialog displays.

14. Type 20 in the Value field and click OK. 15. Start digitizing the points as shown (making a V-shape).



Schlumberger Public

16. When finished right-click and select Done. The control points change to hollow black circles (or dry hole symbols) and the map changes. Take a look at the output window, notice the differences in the average and volume.

17. Save the control points to a monthly.gcp file by right-clicking on the map and selecting Control Points > Save. The Control Points dialog displays.

18. In the File Name field type monthly.gcp and click Save. 19. The Control Points feature is usually used when you want to

add/use a set of points with the same value. If you want to add/use a single value at a particular cell, select Edit > Grid Cell Value. The cell boundary is applied to the grid map.

20. Click on any cell on the grid map. The Edit Grid Cell dialog displays.

21. Change the value in the Replace field. Remember the cell

location so you can check later

22. Click OK. If your value changed dramatically, it could influence the neighbor cells and impact the average and volume calculations.

NOTE: You can choose not to display the control points at this time by selecting View>Wells. Take a look at the output window. Notice the differences in the average and volume.

If you do not want to use the control points, select Edit >Control Points>Clear.

To use previously saved control points, select Edit>Control Points>Open and browse to the desired file and open it.

NOTE: You can always navigate through time, select the date, set the date increment (for navigation and animation). These options can be found from the Step menu.

The Animation option can also be accessed from the Tools menu. The setup is identical to that addressed in Bubble Map.

Scatter Plot provides a unique tool for analyzing multiple variables at the same time and their interactions over time. Besides being a mapping tool, Scatter Plot is also plotting tool that has the capability of presenting any combination of variables on the two axes.

Scatter Plot has built-in date dimension (Date is not used explicitly as a variable as in Map XY). It can be presented at any time, and can be animated over time. The module has the most number of associated tools/utilities to help users effectively perform many types of analysis.

In this module, you will learn to set up single-graph and multi-graph scatter plots, customize the output, apply the tools/utilities associated with the module, and use statistical functionalities (e.g., Histogram, Monte Carlo Simulation).

Scatter plot is a strong analytical tool for production data. You will focus on wells that have (monthly) production data.

Learning Objectives In this section, you will successfully learn how to perform the following procedures within this workflow:

Set up scatter plots Sets and set operations Use tools/utilities Work with histogram and Monte Carlo simulation Use mapper synchronization

Lesson 18 Scatter Plots (single-graph and multiple-graph)

In this lesson you will set up scatter plots.

Exercise 29 Setting up Scatter Plots (single graph and multiple graph)

To set up a scatter plot:

1. From the Filter pane, expand the Table Data node and select the Monthlyprod table.

2. Select Analysis > Scatter Plot. The Open Scatter Plot window displays.

3. Select the Monthly dataset and click Edit. Click Next. 4. Locate the Data Grouping section of the dialog and select

Completion from the Group by list. Click Finish. The scatter plot displays.

5. Locate the Scatter Plot Properties section of the Properties pane.

6. Set the Number of Graphs to 1 (then Current Graph is 1). 7. Select Oil.Cum as the X Variable. 8. Set Scale Type to Linear. Leave the Minimum, Maximum,

and Increment values at their default setting. 9. Select Monthlyprod.Oil as the Y Variable. 10. Set Scale Type to Linear. Leave the Minimum, Maximum,

and Increment values at their default setting. 11. On the last month of the production history, you do not get to

see many wells (each well is represented by a point/symbol on the plot). Select Step > Select Date and select 06/1/1970 from the list of available dates. Click OK.

12. From the Properties pane, change the Y-Axis scale Maximum to 2500.

13. Zoom in on the desired area.

14. Edit the plot headers as desired to get a better presentation as shown below.

15. In the Scatter Plot Properties section of the dialog, change the Number of Graphs to 2.

16. Set the Current Graph to 2. Specify the following:
