Pie Property Tab

View image

The Pie Property tab, found on the Time Slice Property Page dialog box, provides options for you to draw time slice pies that compare more than one kind of parameter and see how their quantities change over time (For example, you can compare cumulative production to cumulative injection). Neither bubble mapping or time slice bubbles offer this option.

Time slice pies offer you up to 20 different well parameters to compare (For example, cumulative production gas and water production monthly average). Each slice of the pie represents a different parameter.

For best results, we suggest selecting only five or six parameters; otherwise, your pie slices become so small that comparing the parameters becomes difficult.
You may already be used to seeing these parameters in your tickets, but the information may not be the same. For example, the cumulative oil that displays in the well ticket is for the entire life of the well, while the cumulative oil in the time slice is up to the end of the time slice period.

Create a time slice pie

Look at the <OK> and <Apply> buttons at the bottom of the tab. If they appear dimmed, it's because you selected the Show Text Only check box on the Text Property tab, which means that you selected to only show text on the map, and time slice pies aren't text. If you want to create time slice pies, you need to go to that tab and clear the check box before you continue with the rest of the steps.
In the Results List list, select for which result list to draw time slice pies.
The Parameter List box displays all the well parameters in your map that are available for comparison. Select a parameter that you want to display in your pie, and click <>> to move it to the Selected Parameter List box. For example, if you are interested in seeing how much oil, gas, and water each well in your area produced, select Cumulative Productions.

The more parameters you select, the smaller the slices of the pie become. You can select up to a maximum of 20 parameters for a pie. If you select more, or try to move all the parameters to the Selected Parameters List window, GeoVista will display a warning message.

In the Bubble Size list, select the relative size of the time slice pie, compared to the scale of the map. Keep your bubble fairly small so that you do not fill up your screen. The default size is 5. Use the larger bubble sizes if you want to zoom in and look at a single bubble.

In theBOE box, adjust the value to account for differences in the relative amount of energy contained in the substance. Read more
In the Scale box, select either a log or linear-style graph. How you set this option just depends on your viewing preference. Read more
Click <OK> to draw your time slice pies and close the dialog box, or click <Apply> to draw your time slice pies but keep the dialog box open to continue to edit how the time pies appear.

Change the fill pattern and color of a parameter

GeoVista automatically selects the colors for each parameter, using the default colors for oil, gas, and water, which are green, red, and blue, respectively. If you want to change the colors, follow these steps:

In the Selected Parameter List box, click on the parameter whose color or pattern you want to change. The Fill Pattern list and the color box update to display that parameter's current settings.
In the Fill Pattern list, select a new pattern for the parameter. While the default pattern for each parameter is solid, you can select a different fill pattern for each of your parameters to make it easier to compare them in the map. See your choices
Click the color rectangle beside the Fill Pattern list to open the Color dialog box. Read more
Select a new color and click <OK>.

Try to set your time slice pies to a color not already heavily used in the map. This will make smaller pies easier to spot.
