[Aleksander-Karlsson]

Problem/task:
Completor requires all columns under the COMPLETION keyword to be filled in, even if not all combinations of valves and annulus content require all columns. E.g. it does not make sense that the annulus packer element requires input in the device type or blank portion column.

Possible solution:
Improve Completor to be more flexible and handle empty columns. It should be possible to default or leave out columns not needed in specific situations. The blank portion option should also be deleted.

Description:

The packer annulus content (PA - with zero length) should not need dummy values in the following columns: well diameter, tubing diameter, roughness, VPJ, valve type, device number and blank portion.

"Valve type" PERF means that there is no inflow control devices, thus it should not be necessary to define #valves/joint and Device# for this "valve type".

Example:

COMPLETION
