Histogram selecting wells

Selecting Wells

The Histogram Module can display any subset of wells in the project.  To change the wells shown, select Wells> from the menu bar at the top of the Histogram Module

All Wells - This option selects all wells in the project.

Wells By Data Criteria - This option opens the Wells By Data Criteria tool that selects wells by specific data criteria.

With Selected Curve - This option selects only the wells with the currently selected curve in the Data Definition tool's Log Curve tab.

Map Selected Wells - This option selects the wells currently selected in the Map Module.

Main Selected Wells - This option selects the wells currently selected in the Main Module.

Cross-Section Wells - This option selects the wells currently selected in the Cross-Section Module.

To switch between wells, select either the desired well on the dropdown at the top of the Log Crossplot Module or use the left and right arrows to scroll through the selected wells.

Plot Single/Combine All Wells

Petra can either plot the log data points from a single well or from multiple wells in aggregate.  To switch between these two modes, select Wells>Plot Single Well and Wells>Combine All Wells.  Note that showing multiple wells will remove the curves displayed on the right side of the screen – after all, with data points from multiple wells, which curves would you show?
