To create an Excel chart showing world oil reserves vs. time, you can follow these steps:

Step 1: Organize your data in columns.
- In column A, enter the time periods (e.g., years, quarters, months).
- In column B, enter the corresponding oil reserves for each time period.

Step 2: Select your data.
- Click on the first cell of your data (e.g., A1).
- Hold the Shift key and select the last cell of your data (e.g., B10).

Step 3: Insert the chart.
- Go to the "Insert" tab in the Excel ribbon.
- Click on the "Recommended Charts" button or the "Insert Chart" button.
- In the "Recommended Charts" or "Insert Chart" dialog box, select a Line chart or an XY (Scatter) chart. Both of these chart types can work well for time series data.
- Choose a specific chart subtype that suits your needs (e.g., line with markers, smooth line).

Step 4: Customize your chart.
- After the chart is inserted, you can customize it by selecting different chart elements, applying chart layouts and styles, modifying axis scales, and adding labels or titles.
- Right-click on any chart element to access various customization options.

Step 5: Format the chart.
- To format the chart, click on the chart to activate the Chart Tools menu.
- Use the options in the "Design," "Layout," and "Format" tabs to change the chart's appearance, colors, fonts, gridlines, and other visual elements.

Step 6: Update the chart automatically.
- If you want your chart to update automatically as you add more data, consider using a Named Range or a dynamic table.
- You can create a Named Range by selecting your data and then going to the "Formulas" tab, choosing "Define Name," and giving it a name. This makes it easier to refer to the data range in your chart.
- Alternatively, you can use a dynamic table by converting your data into an Excel table. With a table, any new data you add will automatically be included in your chart.

By following these steps, you should be able to create an Excel chart showing world oil reserves vs. time.
