ASCII options tab

 

The Options tab controls how Petra loads overlapping data between the project and the imported file.  

Over Write With Incoming Nulls

Normally, Petra won't overwrite a value in the database with a null from the import file.  This option instead forces Petra to overwrite a value in the database with nulls from the import file.  

Update Blank Well Header Locations, Tops, and Zone Items Only

This option will only copy data from the imported file into blank entries.

Replace Current Perfs, Cores, IPs, DSTs, and Casing with Imported Data

By default, Petra attempts to only add new Perfs, Cores, IPs, DSTs, and Casing entries to the project.  This option instead completely erases all the existing entries in the project and adds Perfs, Cores, IPs, DSTs, and Casing from the import file.

Append Well Remarks If Loaded

By default, Petra overwrites the well remarks in the project with those from the import file.  This option just appends well remarks rather than completely replacing them.

Convert Canadian UWIs to Standard 16 Character Form

This option converts 14 digit Canadian API numbers to 16 character API numbers during the import.

Load All Data To Primary Completion Well Only

With this option selected, Petra only imports primary completions with API numbers ending in 0000.  Data from other completions (0001, 0002, etc) are merged with the primary completion.  For 16-character Canadian UWIs, the first 14 characters are used.

Add Multiple Top Values as Repeated Tops

This option saves multiple formation tops for the same well as repeat tops in Petra database.

Well Update Mode

This dropdown selects how Petra loads new wells and treats wells already in the local database.  Add New Wells to Database and Update Selected Wells will both create new wells, and overwrite the selected data for wells already in the database. Add New Wells Only will create new wells, but will not overwrite any data in wells already in the database. “Update Selected Wells Only will overwrite selected data for wells in the project, but will not create new wells.

Numerical NULL Values Are Indicated By

Petra recognizes the most common null placeholder,“-999.25, on its own.   This option sets the non-standard strings of text or numbers Petra should recognize as null values.

Date Format In Import File

This option sets the formatting of dates in the import file.

Remove the Following Characters From the UWI

API numbers are commonly broken up by dashes, slashes, or other characters.  This option removes non-standard characters from the UWI before loading them into the project.

Load Zone Item Name and Value into ZONE

For datasets where each data item is its own row, this option sets the destination zone for the selected data items.  Note that these datasets can only put data into a single zone at one time.

Print Hdr List

This option creates and prints a list of the well header items.
