The well tab displays and modifies information about the selected well on the well list. Typing a value in the appropriate entry field will change that field.
Every well in the Petra database has a different "Unique Well Identifier" (UWI). The UWI is a 1 to 20 character identifier and is typically the API number of the well. When a well is imported into the Petra database, it's automatically assigned a unique "Well Sequence Number" (WSN). The WSN is simply the order in which the well was brought into the database; the first well imported has a WSN of 1, and the 21st well in the database has a WSN of 21.
Petra does not have a maximum number of wells however, the number of wells imported can be limited per import session if needed.
See, Add new well limiter option.
