Perforations
Perforations are independent of the other data cards but are also keyed off of stage. Each perforation interval defined by the perforation header can contain a series of perforations.
With completion header information already imported or entered, stage-level perforation data can then be imported or entered. The data rules for perforations are:
- You cannot have duplicate stage numbers.
- Stage intervals cannot overlap.
- Perforation intervals cannot overlap.
- Required fields for stimulation data include Stage, Start Depth, and End Depth.
The Perforations data card has two view options:
|
Headers & Perforations |
The interval defined by the start and end depths in the perforation header includes all perforation intervals for that stage. If you add, edit, or import perforations, the start and end depths in the perforation header update accordingly. For example, if the perforation header interval for stage 3 is 10,000 ft - 10,200ft, and you add a perforation with a start depth of 10,220 and an end depth of 10,240, the end depth of the perforation header changes to 10,240. |

Perforations Only |
This view displays the stage, interval depth, and perforation data in a flat table. |
See the Perforations Glossary for a definition of each term.
To manually enter Perforation data, click Insert to add a row, and then enter (or select) a value for each field. If the value you enter is not valid, the cell will be outlined in red. A tooltip will explain the error.
